The Bay of Biscay is one of the richest stretches of the Atlantic, a deep-water bay where the continental shelf drops away steeply and marine life gathers close to land. This boat tour takes you out from the Basque coast to look for cetaceans, the group that includes dolphins, porpoises and whales. Sightings are never guaranteed, since these are wild animals, but the combination of deep water and a busy food chain means that common dolphins are often seen, and the trip also offers views of the coastline from the sea, seabirds riding the swell and a chance to understand how the ocean shapes life along the shore. With a guide on board explaining what you see, the outing is both a wildlife trip and a lesson in the local sea.
How it works
The tour runs on a small boat with a limited number of passengers, departing from a harbour on the coast near Biarritz, with the exact meeting point and time confirmed when you book. Trips usually last a couple of hours, with part of the time spent travelling to the area where animals are most likely to be found.
The sea can be choppy, so people prone to seasickness should take precautions beforehand, and you should expect spray on the open deck. Cancellations because of weather are common, and operators normally offer a new date or a refund.
What you may see
Common dolphins are the stars of the bay, travelling in lively groups and sometimes riding the bow wave of the boat. Bottlenose dolphins and porpoises are also possible, and in some seasons larger visitors such as fin whales or pilot whales pass through the deeper water. Seabirds such as gannets and shearwaters are frequently seen diving, and the guide will point out where birds are feeding, since this often signals fish below.
Even when the animals are shy, the view of the coast from offshore is superb, with the cliffs of Biarritz, the lighthouse and the Pyrenees all in one frame.
Responsible watching
Good operators follow a code of conduct that keeps the boat at a safe distance, avoids chasing animals and limits the time spent with any group, which protects the animals and often gives better views. Listen to the guide and keep noise down when animals are near. Binoculars are a useful addition, and a camera with a zoom lens helps, but keep it protected from spray. The season matters, as summer and early autumn offer the calmest seas and the best chance of sightings, while winter trips are often cancelled by weather.
Making the most of it
Wear layers, a windproof jacket and non-slip shoes, even in summer, because the sea is cooler than the land. Bring sunglasses, a hat and sun cream, and a small bag that can get wet. Take a seasickness tablet an hour before departure if you are unsure, and eat a light meal.
Children can enjoy the trip if they are comfortable on boats, and operators usually provide life jackets. Check the weather forecast the day before, and have a flexible plan, such as a morning on the beach, in case the trip is moved or cancelled.
