68,817-acre Quiberon and Belle-Île. South West 4 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 south west 4 angler-scale survey window. The water tops out around 131 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. What follows comes from the same scoring engine that paints the spots above.
Traced from the shoreline, Quiberon and Belle-Île - South West 4 runs 68,781 acres with 41.8 miles of edge. Nearly circular (index 1.1), so the story is the bottom, not the bank. About 3% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. The basin spans about 14.9 mi end to end and 14.3 mi across at its widest. For a second option, Golfe du Morbihan - South East lies 9 mi northeast.

Les profondeurs et les points de structure proviennent de la grille bathymétrique officielle du Shom. Les données servent à préparer la pêche et ne doivent jamais être utilisées pour la navigation.
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.

In spring, european seabass run shallow here, mostly 3 to 25 ft. Summer pushes them deeper, 2 to 30 ft, and winter fish settle into 10 to 55 ft. SHOM-grid point is the standout, a point at roughly 39 ft, rated good for fall european seabass. Time it for early morning and the evening. You won't need more than a surface lure or a paddle-tail soft plastic most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 25 ft | dawn & dusk | open water | Paddle-tail soft plastic, Shallow minnow plug |
| Summer | 2 to 30 ft | dawn & dusk | open water | Surface lure, Paddle-tail soft plastic |
| Fall | 4 to 40 ft | dawn & dusk | SHOM-grid point (39 ft) | Slim metal lure, Minnow plug |
| Winter | 10 to 55 ft | midday | SHOM-grid channel edge (66 ft) | Slow soft-plastic shad, Suspending minnow |
Early season atlantic mackerel use the shallows, holding in 5 to 45 ft. Expect a summer slide to 15 to 80 ft, then a winter hold in 30 to 120 ft. Put SHOM-grid current seam first on the milk run — a current seam near 52 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a feather rig or a small vertical jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 45 ft | dawn & dusk | SHOM-grid point (39 ft) | Mackerel feather rig, Small silver jig |
| Summer | 15 to 80 ft | dawn & dusk | Sharp break (17 ft) | Feather rig, Small vertical jig |
| Fall | 10 to 65 ft | dawn & dusk | SHOM-grid current seam (52 ft) | Compact silver jig, Sparse feather rig |
| Winter | 30 to 120 ft | midday | Deepest basin (129 ft) | Small deep jig |
Come spring, look for atlantic pollock tight to the bank in 8 to 100 ft. Expect a summer slide to 10 to 131 ft, then a winter hold in 21 to 131 ft. Start at SHOM-grid point. It's a point holding about 39 ft of water and rates prime come summer. Prime time lands in early morning and the evening. A surface plug or a baitfish swimbait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 100 ft | dawn & dusk | Rock reef (5 ft) | Sandeel-pattern lure, Soft-plastic shad |
| Summer | 10 to 131 ft | dawn & dusk | SHOM-grid point (39 ft) | Surface plug, Baitfish swimbait |
| Fall | 12 to 131 ft | dawn | Rock reef (5 ft) | Metal jig, Minnow plug |
| Winter | 21 to 131 ft | midday | Sharp break (17 ft) | Slow metal jig, Weighted soft plastic |
In spring, saithe (coalfish) run shallow here, mostly 12 to 131 ft. Summer keeps them at 13 to 131 ft, and they winter in 18 to 131 ft. SHOM-grid current seam is the standout, a current seam at roughly 52 ft, rated prime for spring saithe (coalfish). Time it for early morning and the evening. You won't need more than a speed jig or a heavy paddletail most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 12 to 131 ft | dawn & dusk | SHOM-grid current seam (52 ft) | Slim metal jig, Paddletail |

No official 2025 EEA designated bathing-water point matched within 400 metres of this SHOM-grid shoreline. This is an access-evidence gap, not a statement that public fishing access does not exist. Verify local fishing rights, land ownership, posted restrictions, protected areas, tidal and surf safety, and municipal permission before entry.
Private land and private launches need the owner's permission — please ask first.
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 - South West 4 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.

Quiberon and Belle-Île - South West 4 is about 131 ft (40 m) deep at its deepest point. 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.
