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?

I took my 2nd trip with Caramel Trail recently and it was an outstanding experience (just like the 1st time). Caramel Trail's attention to detail is second to none. Every step of our trip was meticulously planned and every driver and tour guide was well organized, knowledgeable and friendly.

Caramel Trail assisted us on our travels to Spain and Portugal. We cannot say enough great things about their recommendations, travel support and guidance throughout our entire trip. Whenever we contacted Angela or Paloma they responded within minutes every time. They literally made us feel as if we were their only clients. When our trip was disrupted due to weather on Madeira, Caramel Trail had us rebooked and accommodated within hours, which was amazing. We highly recommended them to anyone traveling and needing top notch support!

What an amazing experience with our trip to Spain and Portugal planned by Samuel and Paloma from Caramel Trail. From the very first email to the very last, it was just perfect! This was our very first time in Spain and Portugal (in Europe in general) and how many great memories we made. Everything was so well planned, every choice was perfect and Samuel and Paloma available to us 24/7. Every single person we interacted with was so nice and kind and so knowledgeable, we learned so much. Note that we were traveling with 3 kids, one of them being 6 years old but everyone was so accommodating and always mindful of them, it made the trip so easy. Thank you so much for giving us such a wonderful experience.

Angela helped my husband and me plan our trip to Bilbao, San Sebastian and Barcelona. Her suggestions and communication from the start were exceptional. She listened to our desires, worked within our budget and executed a flawless trip. Everything, from hotels to restaurant reservations to guides to drivers to travel arrangements, was first-class. Plus, she kept in touch with us throughout our trip so as to be proactive to any concerns or glitches which might have arisen (none did). We would recommend Caramel Trail wholeheartedly.

We just finished a tour of Portugal. Angela and Paloma took care of all the details of the trip to include airport transfers, hotels, gastronomy and tour guides. We basically flew into the country and they took care of the land portion of the trip. They remained in constant communication during the trip and answered all questions in less than 5 minutes. All of their guides and car/van drivers were professional and were able to communicate in English (and in Spanish also). Several experiences were tailored made for our trip, such as hiking through a vineyard in the Duoro region, a gastronomic tour of Porto, and a nice Sunday drive through the beaches of Algarve, among others. Our driver was excellent and made suggestions on the spot for our lunches, dinners, spots for sightseeing and photography, etc.

We had the best trip to Spain, including Madrid, Toledo, Granada and Seville. Angela and Paloma did an outstanding job of planning a perfect 9 days for us - from start to finish we thoroughly enjoyed our accommodations, our drivers, guides, tours and experiences. My only regret is not having more time - it definitely left us wanting a bit more time to explore each area. They also went above and beyond to help when my niece was ill for a couple days on our trip. We so appreciated the assistance they offered and last minute changes to our itinerary. All in all, it was a wonderful experience and one that we will never forget!

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.

Caramel Trail arranged an amazing trip for our family to Spain and Morocco. All of the hotels were great and located in key areas of the cities we visited. The guides and drivers were wonderful - very informative and attentive. They were always available for any questions. We were absolutely thrilled with our experience and would give more than 5 stars if we could!

We had an absolutely fantastic trip to Spain and Morocco, with every detail handled by Carameltrail, specifically Angela, and then also Paloma during the actual travel. We loved working with Angela, going back and forth to fine tune our itinerary. She asked the right questions to make sure the itinerary matched our preferences for tours, hiking trails, photo ops, types of lodging, guides, etc. She handled every detail to perfection, making hotel reservations, plane and rental car reservations, drivers... everything! The lodging they set up for us was spectacular and memorable with unique and friendly boutique hotels. And when we had questions during the actual travel, Angela and Paloma were always available, at all hours!!! They even surprised us with special tips during the travel so we were able to enjoy some of their local favorite eats and activities. We highly recommend Carameltrail and will use them again!!

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!

We put the itinerary together with Samuel who had tremendous knowledge of places, guides, transport, restaurants and experiences. They looked after us throughout and responded instantly to any requests or concerns. An absolutely great travel experience.

What a great trip. Caramel Trails listened to what we wanted and provided a wonderful experience. From Lisbon, the university in Coimbra, Wine Tasting in Porto and the Douro valley, to Templers in Tomar and of Course Sintra. The guides were personable, and knowledgeable, and always on time.

We had such a wonderful time on our trip with CaramelTrail. We had wanted to walk/hike throughout Northern Spain, studying the culture, visiting wineries, tasting pintxos and tapas along the way. Samuel and Paloma were able to provide all of these opportunities. Both drivers and guides were so helpful, knowledgeable and fun to be with. We highly recommend using Caramel Trail as a travel agency.

This past March my wife and I returned to Spain for our second travel experience with CaramelTrail. Nothing has changed, it was as wonderful as the first time. Our initial aim was to visit Valencia because of our fascination with all things paella. But, this trip was so much more than that. We traveled to the Matarrana region, the Tuscany of Spain. Our visits to Fuentespalda and Siguenza were incredible. Near Leon, we went to a remote village to visit Bodega El Capricho, a stunning restaurant specializing in beef. Actually it's so much more than a restaurant. It is an ox farm and vineyard as well. We had a private tour of the farm, meat curing cellar, and the wine cellar followed by an amazing tasting menu. Spain is a beautiful country we enjoy very much. What brings the experience to another whole level is CaramelTrail. Paloma and Samuel, once again, did an incredible job of organizing and making sure that our time in Spain was everything we hoped for. The choice of guides, chauffeurs, hotels and paradores, and the gastronomic experiences set CaramelTrail apart from other agencies. We recommend CaramelTrail to anyone that wants an experience of a lifetime.

Carameltrail is a wonderful travel agency! I would highly recommend them without hesitation. Angela and Paloma planned the itinerary for our family of 10 from Madrid to Barcelona. They planned several side trips that were amazing (Toledo, Segovia, Costa Brava). From the moment we got off our plane, everything was planned for us to perfection. Thank you, Angela and Paloma, for our wonderful memories. Bravo to Carameltrail.

100% Confidence in Angela and Paloma. They created and executed an amazing 9 day trip for my family of 9 to travel from Barcelona, to Seville, to Cordoba, to Malaga, and then Granada. Angela was so patient in the planning process. Listened to our objectives, created a plan, and then updated it many times until we thought it was perfect. And, it ended up being more than perfect. Once we arrived in Barcelona, Paloma took the lead and was available 24/7..immediately responding on WhatsApp. At every turn, transportation was top notch. Great drivers and great vehicles. Hotel at Malaga was 5star...exactly what we needed...a warm, cozy LHW oasis after a long week situated perfectly in a dynamic walkable city. All the activities they arranged were either super fun, super delicious, or super cool. Site seeing, food tours, bike tours...the guides were also so easy going, relatable, and accommodating. They always had the best restaurant recommendations...no need to question them. Every reco was perfect. We would recommend them 100000%.

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.

My wife Lauri and I just returned from 10 days in Spain. We were lucky to have worked with Samuel Rojo and Paloma Benty from Carameltrail. They both provided us with great recommendations on what to see and how many days in each city we needed. They were excellent in providing Really knowledgeable guides for us in Madrid, Toledo, Barcelona and Malaga. Also, I became ill during our last few days in Malaga and they were on the phone providing us with medical advice, changing our rail tickets , making sure all of our drivers were able to meet us and help with our luggage. The concern they had for us was wonderful! We would highly recommend them to anyone traveling to Spain who would like to travel independently of a large group. Again , Thanks to Samuel And Paloma Les Shelton and Lauri Vinick

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!!!

5 Stars – Absolutely Exceptional Service! I recently booked a vacation with Carameltrail, and I can’t recommend them highly enough! From start to finish, the experience was seamless and stress-free. The team (Samuel and Paloma) was incredibly knowledgeable, attentive, and genuinely cared about creating the perfect itinerary for me. They took the time to understand my preferences and suggested unique destinations and activities I wouldn’t have discovered on my own. Every detail — from flights, private drivers/car service and accommodations to tours and local experiences — was perfectly coordinated. I felt supported the entire time, and any questions I had were answered quickly and professionally. This was hands-down one of the best trips I’ve ever taken, and it’s all thanks to their expert planning and personal touch. If you’re looking for a travel planner that truly goes above and beyond, look no further. Last year Carameltrail planned Spain for me and this year was Portugal. Exceptional experience. I’ll definitely be booking with them again!

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.

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.

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!!
