13,196-acre Quiberon and Belle-Île. North West 3 France saltwater fishing map with official SHOM 100 m bathymetry, source-qualified fishing spots, official regional fish evidence, seasonal forage guidance, public shore-use context and current-rule links. Quiberon Bay, the peninsula and Belle-Île approaches, spanning protected sand, rocky points and Atlantic current. This page covers the north west 3 angler-scale survey window. The water tops out around 71 ft. The depth chart comes from Shom (Service hydrographique et océanographique de la Marine) bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
The outline encloses 13,198 acres, worked by 57.3 miles of shoreline, with 3 islands in the mix. With a shoreline index of 3.6, this water is all arms and coves — edge habitat well beyond its acreage. 68% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 7.2 mi of water from one end to the other, 5.4 mi at the beam. Lorient and Groix Coast - South West 4 sits 9 mi southwest — the closest neighbouring chart.

Regional occurrence supports a search target, not equal abundance, child-specific catch rate, retention permission or a promised catch. Current national, EU, regional, protected-area and species rules always control. The roster may combine exact-water monitoring with habitat-filtered official regional evidence; it does not imply that every species is equally abundant throughout the mapped section.

Access data: European Environment Agency — 2025 Bathing Water Directive Sites (France). Confirm conditions and fees locally before you launch.
Season dates, license requirements, and size and bag limits for France waters are set by the Légifrance (current French recreational sea-fishing minimum sizes) — and special regulations can apply to Quiberon and Belle-Île - North West 3 specifically, so confirm the current rules before you fish. French recreational sea-fishing rules combine current national and European species measures with façade, prefectural, marine-protected-area, harbour and local access controls. Check live minimum sizes, quotas, seasonal or method closures, marking requirements and any no-take zone before every trip. A SHOM contour, fishing-spot marker or designated bathing-water lead is planning context only and never permission to fish, retain a catch, park, launch or enter restricted shore or port property.
