Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
La Bayonnaise presents a compelling blend of historical narrative and underwater exploration within Galicia's coastal waters. Remains of a French military sailing corvette, intentionally destroyed off the Finisterre coast in 1803, form the core of this dive site.
Under pursuit by the English ship H.M.S. Ardent, its crew ran the three-masted, copper-lined vessel aground, setting it ablaze to prevent capture, resulting in a midnight explosion.
The shipwreck is currently located at a maximum depth of 6 meters / 19 feet, accommodating basic diving levels, including those with a PADI Open Water Diver certification or even Discover Scuba Diving participants. Access to the site can be made via boat or directly from Langosteira beach.
Divers primarily encounter scattered wooden hull fragments from the 310-ton vessel, alongside identifiable cannons and ammunition, providing a rich archaeological experience on a sandy bottom. Its shallow nature allows for extended bottom times, encouraging thorough investigation of these historical artifacts.

Current conditions near La Bayonnaise show 20° air, 16° sea temperature, 1.3 m waves, and 15 km/h wind. Forecast data is refreshed regularly to ensure accuracy.
Best Time to Dive
For optimal dive experience at La Bayonnaise, consider visiting between May and August, aligning with moderate dive scores. These months bring comfortably warmer air temperatures, typically ranging from 15°C to 20°C / 59-68°F, enhancing comfort both in and out of the water. Rainfall remains at its annual low, averaging between 1 and 3.5 mm, which helps maintain better visibility. Average wave heights are crucially reduced, often staying between 1.5 and 1.8 meters, simplifying both boat and shore entries. Diving outside this window, particularly from January to March, often entails wave heights exceeding 3.5 meters and increased rain, making conditions considerably more challenging.

Dive Experience & Conditions
Dynamic coastal currents characterize the dive experience at La Bayonnaise in this Spanish region. Tidal movements can influence underwater clarity, and while specific visibility ranges are not consistently reported, they vary depending on the day's conditions. Resting on a sandy bottom, the wreck's substrate allows particulate matter to be stirred, potentially affecting visibility. A shallow site, reaching 6 meters / 19 feet, it remains particularly sensitive to surface weather patterns. Strong winds and elevated wave action can substantially decrease underwater visibility and complicate entries or exits. Divers should be prepared for a relatively exposed environment, necessitating attention to swell and current, especially when entering from Langosteira beach.
Dive Difficulty & Safety Guidelines
While the La Bayonnaise dive is rated for basic skill levels, adhering to proper safety protocols is crucial. Due to its archaeological status, removing or disturbing any artifacts from the wreck is strictly prohibited. Its shallow nature, suitable for Open Water Divers, means the Finisterre coast's exposed environment can lead to quickly changing conditions. Divers must consult local weather forecasts and tidal charts, as strong currents and significant wave heights can pose challenges, particularly during shore entries or boat operations. Practicing excellent buoyancy control is essential to prevent accidental contact with the delicate historical remains and the sandy seabed. Diving with a local guide, who understands the site's unique characteristics and current patterns, is highly recommended.
