Tenerife: Underwater Walk – Sea Trek Experience

If you’re looking for a way to see Tenerife’s vibrant marine life without the hassle of diving or swimming, the Sea Trek experience in Los Cristianos offers a unique and accessible option. This helmet walk is designed to be safe, fun, and suitable for nearly everyone — from kids over 8 to seniors — and it provides a fascinating glimpse into the underwater world without getting your hair wet or needing prior training.

Two things we particularly love about this experience are its personalized attention, thanks to small group sizes, and the up-close view of marine life in crystal-clear waters. However, a potential consideration is that it lasts only about 30 minutes underwater, so it’s not a full day of exploration but more of a taste of the underwater environment.

This tour is best suited for travelers who want a safe, hands-on underwater adventure that’s easy to access and doesn’t require physical exertion or prior experience. It’s perfect for families, first-time snorkelers, or anyone curious about marine life but hesitant to try traditional diving.

A Practical Overview of the Tenerife Sea Trek

The Experience at a Glance

The tour begins at the Paseo Aquilino in Los Cristianos, a convenient and scenic starting point. From there, you’ll be taken through a safety briefing and equipment fitting, setting the stage for your underwater adventure. The actual underwater walk lasts about 30 minutes, but the entire activity—including preparation and debriefing—takes roughly 1 hour 30 minutes.

What makes this experience stand out is the special helmet used, which allows you to breathe freely and walk on the seabed. It’s almost like walking on the moon—floating with a sensation of zero gravity while observing marine life close-up.

How the Itinerary Unfolds

The tour starts at Paseo Aquilino, then moves to the safety briefing, where the guide explains the equipment and ensures everyone is comfortable. After a quick transfer by van, you’ll arrive at the water’s edge in Los Cristianos, ready for your underwater stroll.

Once in the water, you will explore volcanic rock formations, vibrant fish, and marine flora. Several reviews mention how the guides are professional and attentive, which helps you feel confident. The guided part of the tour lasts about 30 minutes, during which you’ll enjoy a relaxed walk on the ocean floor, observing marine life that appears lively and colorful in the clear waters. Afterward, there’s a quick return to the meeting point, wrapping up the adventure.

The Equipment & Comfort

All necessary gear—wetsuits, proper footwear, and the helmet—is included. The wetsuit keeps you warm, essential because ocean temperatures can vary, especially in the Canary Islands. The helmet sits comfortably and allows you to breathe normally, making the underwater environment accessible to everyone, regardless of swimming ability.
