Experience Tenerife’s underwater world with a safe, easy underwater walk using special helmets—no swimming skills needed, perfect for all ages.
If you’re visiting Tenerife and craving a thrill that’s gentle on skills but big on wow factor, the Sea Trek underwater walk could be just the ticket. Offered in Los Cristianos, this activity promises an unforgettable adventure where you walk on the ocean floor, breathe normally, and marvel at marine life—all without any diving experience or swimming abilities. Whether you’re nervous about traditional scuba or just want a unique way to see the sea, this guided helmet walk offers a surprisingly accessible option.
One thing we love about this tour is the personalized attention provided by friendly, knowledgeable guides. From the moment you arrive, you’re in safe hands, especially since groups are small—limited to four participants, which means fewer crowds and more focus on your experience. On the flip side, a potential consideration might be the limited duration of the underwater walk itself, which is around 20 to 25 minutes. Still, many find that the combination of safety, comfort, and the chance to enjoy reef and fish close-up more than makes up for it. This activity is ideal for families, first-timers, or anyone who wants to see Tenerife’s vibrant underwater life without the hassle of snorkeling or diving.


When booking this Sea Trek experience, the process is straightforward. You’ll meet at Paseo Aquilino in Los Cristianos, a central spot easy to reach, especially if you plan ahead with parking. Upon arrival, you’ll receive a full safety briefing and equipment fitting—wetsuits, proper footwear, and your signature helmet—before heading into the water.
The entire tour lasts about 1 hour 30 minutes, with the actual underwater walk taking around 20 to 25 minutes. During this time, you’ll stroll along the ocean floor, surrounded by vivid marine life and volcanic rock formations. Many reviewers, such as Amanda from the UK, mention how guides made them feel at ease, even if they initially felt nervous. The helmets are designed for effortless breathing, allowing you to focus on the stunning surroundings rather than worrying about breath control or swimming.
The underwater environment is described as crystal-clear, letting you see a colorful array of fish and other marine creatures. Some guests mention that currents can occasionally make walking a bit tricky, but in a humorous way—adding to the adventure rather than detracting from it. Guides like Jack Sparrow have been praised for their friendliness and helpfulness, taking photos and videos to capture the moment, although these are available at an extra cost.
If you enjoy exploring Tenerife on foot, these walking tours might also suit your style
Starting at Paseo Aquilino, you’ll first go through a safety briefing that covers how the helmets work, safety tips, and what marine life you might see. The instructors are multilingual, speaking English, Spanish, French, Italian, and more, which helps make everyone comfortable.
Next, a short van ride (about five minutes) takes you to the dive site. Here, the guides will assist you in donning your equipment and getting comfortable before entering the water. Many reviews commend the professionalism of guides like Matias, who help nervous first-timers relax and enjoy. Once in the water, you’ll walk along the seabed, with the freedom to wear your glasses if needed—many reviewers mention being able to see fish clearly with their glasses on.
After 20-25 minutes of exploring, you’ll return to the surface, then hop back into the van for a quick ride to the meeting point. The entire process, from arrival to return, is designed to be smooth and stress-free.
All necessary gear—wetsuits, helmets, footwear—is included, ensuring you stay warm and dry during your underwater stroll. The helmets are specially designed to breathe naturally, and guides emphasize safety at all times with small group sizes, giving each participant close attention.
Although photos and videos aren’t included in the base price, you can purchase a package at €25 per couple, capturing your underwater moments. Many reviewers, like Samirah from the UK, appreciated guides taking photos and videos, which help preserve the memory of this surreal experience.

Many guests have shared how friendly and reassuring the staff are. Liubov from the Netherlands mentioned feeling calm and comfortable after the guides explained everything clearly, even if she was initially scared of water. Stevie from the UK called it a “great birthday experience” for his daughter, highlighting that it’s suitable for kids and adults alike.
Zia from the Isle of Man described the experience as “absolutely amazing,” noting how the guides’ warmth and professionalism made her feel safe while exploring the underwater world. The ability to keep glasses on was a big plus for many, allowing clearer views of the vibrant marine life.
The activity’s accessibility is reinforced by comments that it’s perfect for families and first-time divers or snorkelers. For those who are nervous about swimming or diving, the helmet walk offers a “try-before-you-dive” vibe that’s fun and stress-free.

Booking is simple, with the option to cancel free of charge up to 24 hours before. The activity is conducted in small groups—no more than four participants—so expect plenty of personal guidance. The meeting point is located at Paseo Aquilino, with clear directions from the nearby seaside promenade or street entrance. Parking can be tricky in the area, but the PARKIA lot in Los Cristianos is just a three-minute walk away, making logistics easier.
Bring swimwear and a towel, as you’ll want something dry and comfortable afterward. The activity is not suitable for children under 8 or pregnant women, but for everyone else looking for a novel ocean experience, it fits well.
