Shelltone Whale Project • Observation de cétacés runs a small-group whale- and dolphin-watching trip out of Bayonne on the southwest coast of France. From the Quai Pedros on avenue du Maréchal Leclerc, to the nutrient-rich Gouf de Capbreton submarine canyon, this five-hour outing places a maximum of nine guests on a purpose-built boat for intimate encounters with cetaceans from April through November. Our guide Franklin, trained by Pierre Lavagne de Castellan, uses the Shelltone Whale Project’s low-impact approach: slow approaches, quiet observation, and a reading of sea conditions to increase sighting chances while minimizing disturbance. The southern Bay of Biscay around Capbreton is geologically dramatic—the Gouf de Capbreton is a deep underwater canyon that channels cold, nutrient-rich waters upward, fueling plankton blooms and attracting schooling fish, squid, and the predator community that follows. That concentrated food supply is why roughly twenty cetacean species visit the area; you could see common and bottlenose dolphins, Risso’s dolphins, and occasional fin whales or pilot whales, depending on season and luck. The trip highlights both the animals and the marine processes that sustain them: upwelling, canyon walls, and surface feeding spectacles. Because group size is capped at nine, passengers experience a slower, more contemplative tempo than larger tours; guides adapt the route and pace for families and mixed-ability guests, and the operator emphasizes education and respectful distance over sensational chasing. The meeting point is specific: Notre bateau vous attend au Quai Pedros sur l’avenue du Maréchal Leclerc, à deux pas de la guinguette Kulunka. Expect hands-on interpretation about local ecology, spotter routines, and time on deck to scan horizons with binoculars and cameras. Practical details are tidy: about five hours on the water, suitable from age three upward, and best booked between April and November when cetacean presence increases. Bring layers, waterproofs, and motion-sickness remedies; don’t forget a charged camera and binoculars. This is a whale project and a community-based experience as much as a sightseeing trip—Shelltone’s methods and local knowledge make Bayonne’s access to the Gouf de Capbreton not just a viewing opportunity but a chance to learn why this part of the Basque coast supports such dense marine life. For travelers seeking a responsible, small-group marine encounter in Nouvelle-Aquitaine, this outing combines geological spectacle, cetacean behavior, and thoughtful guiding into a memorable half-day at sea. Safety briefings, lifejackets for all ages, and an interpreter in French and English are standard aboard, and guides prioritize calm seas and respectful angles of approach to reduce stress on animals. Booking through the provided link confirms availability; tours are subject to weather and sea-state limits, so flexible scheduling and early reservations during peak months improve your chance of sighting and ensure the small-group experience. Enjoy.
