From Bayonne, these excursions offer the opportunity to explore one of the most remarkable geological features along Europe’s Atlantic coast: the Capbreton Canyon. This underwater canyon, which reaches depths of more than 3,500 meters close to the shoreline, creates conditions that support a rich and diverse marine ecosystem.

Common dolphins, bottlenose dolphins, pilot whales, sperm whales, and many other species regularly frequent this region, where coastal waters meet the depths of the open ocean. Each trip offers the possibility of discovering an environment in constant motion, where every encounter remains unpredictable.

We chose to feature this base for the unique access it provides to this exceptional ecosystem in the Bay of Biscay. The Capbreton Canyon is one of the few places in Europe where the deep ocean comes so close to the coast, creating a unique relationship between the shoreline and the open sea.

Beyond cetacean observation, these excursions offer an opportunity to better understand the influence of underwater landscapes on marine life and the way they shape the presence of the species encountered at the surface.

What We Particularly Appreciate Here

The remarkable proximity between the Basque coastline and the depths of the Atlantic Ocean. A destination that reminds us that some of the ocean’s greatest mysteries can begin just a few miles from shore.
