Experience one of Tenerife’s most unique and accessible underwater adventures. Sea Trek lets you walk on the ocean floor while breathing naturally through a high-tech helmet that keeps your head completely dry — no swimming or diving required.
This activity is perfect for everyone: adults, children, non-swimmers, beginners, and anyone who wants to explore the sea without getting wet or learning to dive. If you can walk, you can Sea Trek.
After a short safety briefing, your guide will help you enter the water from the beach. You’ll descend just a few meters into a calm, protected area with crystal-clear visibility. Once underwater, you’ll follow a specially designed route as colorful fish swim around you.

What To Expect
Step into a world that feels both magical and unreal during this unforgettable Sea Trek experience in Los Cristianos. Instead of swimming or diving, you’ll walk on the ocean floor as if you were landing on another planet — calm, weightless and surrounded by the beauty of Tenerife’s underwater paradise. Your adventure begins with a brief and friendly introduction on land, where our instructor explains everything you need to know. Then, gently and safely, we guide you into the water through the nautical channel — no swimming required at any moment. Once you descend, the real magic begins. For about 20 to 25 minutes , you’ll explore the seabed wearing a comfortable helmet that provides fresh air and a clear 180º view. You’ll be immersed in a peaceful world of colorful fish, volcanic sand and rocks. It’s an experience that feels like walking on the moon — but under the sea. Quiet. Dreamlike. Absolutely unforgettable. At the end of tour, we capture underwater photos so you can relive this moment forever and share it with your loved ones. No experience? No swimming skills? No problem. If you can walk, you can Sea Trek — and discover one of Tenerife’s most extraordinary adventures.

A truly amazing underwater experience

5.00We chose this experience because a. It looked unique vs other under water experiences b. My son can’t swim c. I have a bit of an irrational fear of animal under the water! This experience was brilliant and ticked every box! Matthias and Rasta were great and made all of us feel very welcome and comfortable. We had no idea what to expect really but was very simple; get wet suits on, walk to water put the ‘helmets on’ see some amazing underwater creatures. We went as pairs, it was such a safe experience that our two sons went first, as they were both feeling the heat, before my wife and I went in the second pair. Our sons saw a barracuda, whilst we saw a seq horse (amongst other animals). Would really recommend to families and couples alike. Thank you both for a fantastic experience.
Give it ago!!

5.00Honestly I was absolutely terrified going into it, I’m scared of being underwater but the guides were amazing and patient getting you comfortable with the surroundings. They helped you through the whole process and make it an incredible experience! Under the water they always make sure your okay, if your not they will take you back to the surface immediately. During the process they allowed us to hold a sea urchin which I was not really wanting to do (I didn’t know a lot about them and was nervous) but the guide literally took out his snorkel and placed the urchin on his face to show me it was alright. They are very accommodating and friendly 100% would do it again! They also only allow 4 people max at a time just to ensure you enjoy your experience and can keep an eye on yon As a side note my partner has to wear glasses which is completely fine during the whole experience. Give it a go

5.00This was an incredibly wonderful experience!! The staff was very friendly and they radiated a calm and kindness so we felt very safe! We were able to see a lot of beautiful fish and we were also allowed to hold a crocodile ball each, and a sea horse also looked forward. Recommend on the strongest and we really want to come back!

5.00This was a wonderful experience, and we are so glad we decided to go. We went in the "winter" although it was sunny and in the 20's Celsius. The water was very clear and the current wasn't very strong, as we were very close to the beach, and protected from any large waves. The guides were very knowledgeable and explained everything in detail. They were very friendly and you could tell that they had experience and a love for their job. Both guides made everyone in the group feel comfortable and safe. There were many different types of fish and other sea creatures. It's definitely worth participating. I would recommend this tour for literally anyone. Thank you for a wonderful experience!
Unforgettable Underwater Experience, Even for Non Swimmers :)

5.00Absolutely amazing underwater trekking experience in Tenerife. It honestly felt like walking on the moon and was completely surreal. Mathias and Ayoob were incredibly experienced, super friendly, and so much fun, which made the whole experience unforgettable. It was an amazing experience for me and my husband, and we both enjoyed every single moment. As people who do not dive or swim, this was such a perfect activity for us and made us feel very comfortable and confident. We would 100 percent do this again without hesitation. Highly, highly recommend!! :)
