The international zip line border between Spain and Portugal

Cross the Guadiana River

Looking for adventure? Whether you like your fun in the air, sea or with your feet firmly planted on the ground, Spain has a lot to offer if you’re into extreme sports. And if you consider a Southern Spain itinerary, then Andalucía is a must!

If you are looking for Spain itineraries, you might want to consider zipping over to Portugal for a visit. We don’t mean using the typical transport methods though. You can literally zip down from Sanlucar de Guadiana, in Andalucia, Spain, to Alcoutim, in Algarve, Portugal via a steel cable on the only zip line in the world that will take you over an international border. Isn’t that amazing?

Zip Line between Spain and Portugal

THE INTERNATIONAL ZIP LINE IN SPAIN

The first cross-border zip line in the world is located in Sanlucar de Guadiana in Spain. It is literally a zip line that goes from Spain to Portugal. It crosses the Guadiana River at 50 feet above sea level.

This brilliant experience is not only about getting from one country to another in less than one minute, it is also a form of time travel. The time zones of Spain and Portugal are different. If you start your journey on the coast of Spain at 4 pm, you will arrive in Portugal at 3 pm. This is a unique experience of crossing the border without queuing or passport controls.

Magic: The clock is now 1h back!

Guadiana River between Sanlucar de Guadiana in Spain and Alcoutim in Portugal

THE GUADIANA RIVER: THE BORDER BETWEEN PORTUGAL AND SPAIN

The Guadiana River rises in Ruidera, between Albacete and Ciudad Real, in Spain, and gently descends through the southern half of the Iberian Peninsula. This river flows into Portugal, forming a natural border between the two countries, before emptying into the Atlantic Ocean.

It is thanks to this river that this zip line between Spain and Portugal has been possible. Besides, you can observe beautiful landscapes and enjoy the view during your trip.

There is no need to be trained to complete the journey as all instructions are provided on site. There will be people to help you at both the departure and arrival platform, so all you have to do is listen to the instructions and enjoy your adventure.

A ZIP LINE ACROSS TIME ZONES AND COUNTRIES

The zip line over the Guadiana River offers beautiful views of the landscape between Spain and Portugal and the two border cities. You actually fly through time and go back in time an hour because of the time zone difference between both countries.

Take a ride on the world’s only international zip line that will take you from Spain to Portugal and a one-time zone behind

International zip line in Spain

Users are brought by off-road jeep to the departure platform where they don their harness and helmets. As you leave Spain behind you have the birds eye views of the beautiful Guadiana River and the white-washed village of Alcoutim (Portugal).

You have to look fast though because users reach speeds of up to 80 kph as the line crosses the Guadiana and enters Portuguese airspace. When landing in Portugal, there is a 5 minute walk back to the Alcoutim jetty where a ferry takes you back across the river to Sanlucar.

One of the several cool things about this activity is that when you finish the zipline, you are one hour behind and that gives you some extra time to visit the beautiful Portuguese town of Alcoutim.

If you are not scared of heights and the river rushing below, this one clearly deserves a place in your bucket list. Be aware that you need to be at least 14 years of age, or you will be barred from this adventure. Another factor that might stop you from this adventure of a lifetime is the weight limit, as anyone over 140 kg is not allowed to get on the zip line due to safety measures.

This zip line is the only one in the world that will enable you to cross international border

HOW LONG IS THE ZIP LINE FROM SPAIN TO PORTUGAL?

Enjoy a unique, unforgettable experience by crossing over the Guadiana River from Spain to Portugal. Along the 720 meters zip line length you will cross over the river at speeds between 70 and 80 km/h.

The groups are up to 8 people to the departure platform and after reaching the end of the zip line in Portugal you must walk for about 5 minutes to the Alcoutim jetty that will take you back across the river to Spain.

BRAVE THIS INTERNATIONAL ZIP LINE

Lovers of thrilling experiences have just encountered a new way to travel and enjoy an unforgettable experience: the Zip Wire. This is a zip line with a very special feature: you start in one country and land in another.

Originality and adrenaline come together in this adventurous experience that is increasingly finding followers. Would you like to give it a try?

Our group of 6 experienced a most fabulous trip in Seville, Madrid, Lisbon and Madeira thanks to the expertise of Angela and Paloma from Carameltrail. We have worked with different travel agents over the years, but have never experienced the attention to detail, thoughtful planning, and wonderful execution as we did for this recent month-long trip. Angela listened carefully to our thoughts about the trip and scheduled experiences for us that were varied, authentic, and interesting. The guides that were secured for us were absolutely top-notch! We liked the fact that we had several guides for multiple days. All drivers were excellent and on time for each excursion. Throughout the trip, Angela and Paloma checked in with us each day to make sure we enjoyed our activities and constantly asked if they could do anything else for us. When we asked about hearing Fado music, they secured tickets for us at no extra charge. We have never had such personalized service. We would certainly use Carmeltrail again when traveling to that part of Europe. We wholeheartedly recommend them- you will not be disappointed. They exceeded every expectation we had for our trip.

There are not enough words to thank you for planning a “trip of a lifetime,” to help us celebrate our 50th wedding anniversary. You planned to the minutest of details, an elaborate trip that took us from Madrid, to Morocco, where we visited Casablanca, Volubilis, Meknas, Fez, and Marrakesh; it was a beautiful cultural experience. We then returned to Madrid, where we explored this magical city with its wonderful museums. From there, you planned for us thoughtful visits to Laredo, Córdoba, Sevilla, Ronda, Grazalema, Jerez, the beautiful Costa de la Luz, Málaga, Granada and the amazing Alhambra, and finally the Axarquía area and the beautiful Spanish Mediterranean coast. You made yourselves available to us for any need that might arise, at any time. You were attentive to details, and you obviously are experienced in planning elaborate, special, and personal trips. The guides you assigned for us were knowledgeable and experienced. You selected special, and often historic hotels for us to rest after long days of touring, enjoying culture and food. We were made to feel at home. And we are convinced that we would not have found these hotels on our own, but more importantly, we would not have been able to plan such a beautiful trip on our own, no matter the research.

Angela and Paloma put together a fantastic itinerary for my wife and I. All venues, hotels, restaurants, and guides were outstanding. All travel arrangements went off without a hitch, and they kept in touch constantly to insure that all was well. Would highly recommend Caramel Trails to anyone visiting Spain.

Angela set up a wonderful trip to Spain for us in September 2022. The planning of the trip was painless and Angela listened to our requests and incorporated them into our itinerary. We were all over Spain, and the local guides that Caramel Trail uses were wonderful- both very knowledgeable and accommodating as well as good-humored. Nearly all our transfers went smoothly. The vehicles were very comfortable and the drivers professional. On our last pick-up for our flight home, the driver was not there at the planned time. A text to Angela got a response within a minute or two and the problem (driver had the wrong time) was immediately rectified. The smaller boutique hotels were all in exceptional locations for visiting the areas and for dining. Both Angela and Paloma were always available to us by phone or text and their responsiveness was amazing. We would highly recommend their services for anyone considering a trip to Spain.

Samuel and his team at Carameltrail are terrific. They organized all aspects of our recent trip (fall 2022) to Portugal and Spain, adding several interesting private tours and experiences. The hotels were great, the tour guides very engaging, we saw some truly wonderful sights, and their ongoing availability to answer questions was very helpful. Highly recommend.

Carameltrail is by far the best travel agency I have ever used. Samuel and Paloma planned our three week trip in Spain and Portugal with attention to our preferences and every detail. They were always available to answer any of our questions or make recommendations. My favorite experiences were the gastronomy tours where we were able to eat like the locals. Their tour guides are very interesting, knowledgeable and accommodating. The accommodations were first class. They really provide luxury tours! I highly recommend them.

We would wholeheartedly recommend Carameltrail… For our trip a comprehensive itinerary with details on each location listing the main attractions helped us prepare in advance and, from start to finish, we had a wonderful time on our honeymoon — hotels were all centrally located with high quality rooms and included excellent breakfasts, transfers were right on time with good drivers, tickets for activities and trains were booked in advance and all of personal tour guides were outstanding. Angela and Paloma were readily available for assistance, resolved any unexpected issues promptly and they provided thoughtful touches like a welcome gift at our first hotel check-in with a personal note. Looking forward to planning our next vacation with Caramel Trail!

This was our second trip to Europe using CaramelTrail and working with Samuel Rojo. We wanted to visit Portugal, spend some time by the sea in Spain and have a short visit to Morocco while in Spain. Sam took time to talk with us a couple of times, gave us great advice on creating a manageable itinerary and planned a number of activities/adventures for the kids. CaramelTrail personnel was great (checking on us every day to make sure we are all set for the next day), everything worked perfectly, everyone was on schedule: drivers, tour guides, etc. It was a great trip, all of us had a wonderful time in Portugal, Spain, and Morocco. Thank you very much CaramelTrail team! Muchas grasias y hasta luego!

What a fun way to travel! Samuel and his staff planned our visit to Spain and it was perfect down to the last detail! Our transfers were worry free, with drivers picking us up at every location and taking us back and forth to the wonderful activities they had planned for us. We really got to know each city through bike and segway tours, food and walking tours, cooking classes and a flamenco show. Everyone was kind and friendly, accommodating minor changes with grace and answering all our questions. We’re so looking forward to traveling with you again, it was such a pleasure! Thank you!

Carameltrail did an amazing job. We have booked several other high-end luxury tours thorough other sources and found Carameltrail's the most well planned and managed. The itinerary reflected what I wanted and was complete with notes for our free days. Others have included the "free-day" notes but nothing as useful as Carameltrails.

Booking our trip with Carameltrail was a no-brainer after our first trip to Spain. It was an incredible trip. This time we traveled to beautiful Portugal. They created a custom itinerary that perfectly balanced sightseeing, culture, and relaxation. Everything was so well organized—transfers, tours and accommodations all went smoothly. We loved how they included authentic experiences, like a guided food tour in Porto, a day trip through the Douro Valley wine region, a stop in a small historic village and time to relax along the Algarve coast before heading to Lisbon where we enjoyed a city tour that was custom to what we wanted to see. We ended our trip with an amazing day trip to Sintra and Cascais with a sailboat trip back to Lisbon-definitely a highlight and a perfect way to end our trip. Each recommendation felt thoughtful and tailored to what we wanted out of the trip. What impressed us most was their attention to detail—they provided tips on local restaurants, hidden gems, and even other sights we might want to see if we had extra time. We never once felt stressed; we could just enjoy Portugal’s beauty and culture. This trip was unforgettable, and we definitely recommend Carameltrail for your next adventure!

We worked with Angela and the team at CaramelTrail to plan our trip to Portugal and Spain, and they were absolutely fantastic. When our outbound flight was canceled and we lost a day of travel, they quickly and seamlessly adjusted our itinerary so we didn’t miss a single activity. Throughout the trip, there were several moments where we needed to make changes, and they patiently and efficiently handled every request with zero added stress. They were incredibly responsive to our preferences and even introduced us to a few experiences we wouldn’t have found on our own, which ended up being some of our favorites. I’d highly recommend working with them to create a trip that’s truly tailored to your vision.

Carameltrail did a terrific job planning and organizing our trip to Spain and Portugal. All the hotels, meals, guides, drivers and activities were excellent. Paloma and Angela always answered our questions promptly and checked in regularly to see how we were doing. We could not have been happier with the experience. We particularly enjoyed our trips outside of the main cities, especially our bike ride at Guadarrama National Park, our hike through Donana National Park, our visit to Douro Valley and our sailboat cruise from Cascais to Lisbon.

Carameltrail was exceptional! Angela made planning our trip to Spain so smooth and stress free; arranging every detail from start to finish. She was patient as we changed and rearranged events, and ultimately provided a well blended itinerary based on our expectations and her knowledge. Once we arrived in Spain, Angela and Paloma were available to assist us 24/7 with any need. They checked in every day and guided us along the way ensuring a smooth itinerary. The private tours, transportation, and dinners were exceptional! When our flight home changed unexpectedly and quickly, Paloma was available immediately to coordinate the transportation change. From start to finish, Carameltrail was amazing and I highly recommend them.

We had a lovely trip to Spain & Portugal with Carameltrail! It was a treat having drivers and guides at the ready. They were quick to respond and handle dinner reservations. Communication in whatsapp was stellar. The Tourwriter that you can easily access the itinerary is a plus on your phone. It was truly a wonderful way to experience these 2 beautiful countries. The guides were impressive. One thing that I would do, is let them know that you'd like some free time to shop at various day trips or else you won't get that opportunity. Would love to have shopped a little in Segovia. It was an amazing trip and would highly recommend Carameltrail!

My wife and I recently returned from a two week trip to Spain which was arranged for us by Angela Vigil Martinez and Carameltrail. It was a fantastic vacation from beginning to end. Angela helped us plan out the itinerary and arranged for all our drivers, guides, train reservations, and hotel accommodations. We had several pre-trip telephone calls and emails during which Angela carefully listened to our interests and provided us with many excellent recommendations to plan our itinerary. There were a lot of moving parts, but, despite this, everything worked out seamlessly. Angela was in constant contact with us throughout the trip and incredibly responsive to any minor problems we had. We would definitely use her and her agency for future travel, and are recommending her to our friends. She made this vacation an excellent experience.

Thanks to Caramel Trail, we had a memorable and stress free visit to Spain!! The venues, docents, and experiences in Seville, Granada, and Madrid were all top notch. Would not change a thing. We appreciate their attentiveness throughout our trip as if they were with us the entire time. Out only disappointment is that we couldn’t use the Carameltrail team for all our trips abroad :) Thanks, Angela and Paloma, for orchestrating a magical trip!

My three friends and myself travel to Spain for a week last week and we used Carameltrail services to tailor some culinary, flamenco and city experiences around Madrid and to some nearby cities since we wanted to fully enjoy the capital without wasting too much time traveling by car. Samuel’s suggestions of Segovia, Toledo, Cuenca and Avila not to mention the tour guides selected for us were extraordinary. Our driver Pancho, who drove us to and from the airport and to the cities mentioned was the best! Puntual, respectful, responsible not to mention very patient with four women who sometimes wanted to stretch the time for extra pictures or some last minute shopping. Samuel and Paloma were also superb, very attentive to our needs via text and always helpful either with a restaurant reservation or with some recommendations for our leisure days. We had the best time in Spain largely because we chose them as our luxury travel specialists… and they certainly are!!!

Caramel Trail once again did an awesome job designing and taking care of us on our trip to Barcelona. Every guide and driver was friendly and knowledgeable, and you could tell that they really enjoyed what they do. Samuel and Paloma who run the agency even checked in by text a few times during our stay to make sure everything was going well for us. Top notch service! This is the 3rd trip I booked through Caramel Trail, and have used them previously for a trip to Portugal and Morrocco.

We recently returned from a two-week trip to Spain at Christmastime, which was arranged for us by the dedicated, knowledgeable team at CaramelTrail. It was a trip of a lifetime for our three generations traveling together – from sparkling white villages to intricate alcázars to phenomenal restaurants – all arranged for us by Angela Vigil Martínez over the course of a year. Angela took great care in listening to the goals of multiple family members, helping us fine-tune the itinerary, and to ensure the trip was smooth and comfortable, she arranged for all our drivers, guides, train reservations, and hotel accommodations. We had several pre-trip telephone calls and emails during which Angela carefully listened to our interests and provided us with many excellent recommendations to plan our itinerary. Both Angela and Paloma were frequently int ouch with our group during our trip to ensure all was going as planned. Highlights for us included seeing all the beautiful Christmas lights and decorations throughout southern Spain and Madrid, as well as enjoying the New Year’s Eve and Cabalgata Tres Magos, all unique suggestions from Angela to make the trip most memorable. We have returned home with nothing but the best memories of our family together in España for the holidays… …and we return home with the most enthusiastic praise for CaramelTrail. We cannot wait to work with Angela and Paloma again, next time to travel to Morocco, and we are recommending this team to our friends and to you! The Griego Family (Bay Area, California, USA)

They are a concierge level team that attended to our entire families requests to create a most perfect experience in Spain and Portugal. Their attention to detail, knowledge of the entire country, and choosing only the best hotels, services, tour guides is impeccable. We give the highest recommendation possible.

Recently, my wife and I enjoyed our second trip planned with Caramel Trail. In 2019, we had an amazing trip to Spain. More recently (June 2023), we enjoyed a trip to Portugal with my wife's family. Just like our trip in 2019, Caramel Trail went above and beyond to make each and every experience 5-star! Our hotels in Porto and Lisbon were extraordiary and centrally located, which were very important to us. We had an array of tours, gastronomy, and wine tasting experiences and every guide and driver that we had were exceptional. Caramel Trail also made sure to set us up with outstanding restaurant reservations to make sure that we enjoy the delicious, authentic, and local cuisine of these great cities. After using them for two separate and incredible trips, I cannot recommend Caramel Trail enough!!
