Courseulles-sur-Mer is a working fishing port on the Calvados coast of Normandy, 20 kilometres north of Caen, and one of the region's principal oyster-farming harbours. The Bessin coast here produces both flat oysters (Ostrea edulis) and Pacific oysters (Crassostrea gigas) in beds that span several kilometres of the English Channel shallows, benefiting from strong tidal flows and the mineral-rich waters of the Seulles river estuary.
Local oyster farms at Courseulles-sur-Mer offer guided two-hour visits that begin at the harbour, where participants wear waterproof boots and walk across the tidal flats to the oyster cages at low tide. The guide explains the full production cycle from spat collection through the three-to-four-year grow-out period, during which oysters are turned and graded multiple times by hand. Each year the beds yield several hundred tonnes of No. 2 and No. 3 oysters destined for Parisian restaurants and regional markets.
The tour concludes at the farm's waterside tasting area, where participants shuck their own oysters under instruction and taste them fresh from the sea. Standard pairings offered are a dry Muscadet Sèvre et Maine sur lie or a light Chablis Premier Cru, both recognised matches for the iodine notes of Norman oysters. Tours are available from April through October, timed to coincide with the tidal cycle; most departures are in the morning to ensure low-tide access to the beds.
Pricing is typically €15–€25 per person and includes the guided walk, shucking instruction, and a tasting portion of six to twelve oysters. A dozen fresh oysters can be purchased to take away at wholesale prices of €6–€10 per dozen. Advance booking is essential as each tour is limited to eight to twelve participants. The Courseulles tourist office coordinates bookings for multiple farms in the area.
Courseulles-sur-Mer sits on the former Juno Beach sector of the D-Day landings, and many visitors combine the oyster experience with a morning at the Canada at War museum nearby before heading to the port for lunch.

Tips for visiting
- Wear warm, waterproof clothing — the tidal flats are exposed and wind off the Channel is cold even in summer.
- Book at least one week in advance in July and August; tour places sell out quickly during peak season.
- Tours are timed to low tide; confirm the exact departure time when booking as it shifts daily.
- If taking oysters to go, ask the farm for ice packing and consume within 24 hours.
- Non-oyster eaters in the group can still join the walk and demonstration; the farm usually offers smoked fish or rillettes as an alternative tasting.
Frequently asked questions
Do participants need to shuck their own oysters?
The guide demonstrates the technique and participants are invited to try, but it is not mandatory. The guide will shuck any oysters that visitors prefer not to open themselves.
Are tours conducted in English?
Most farms at Courseulles offer tours primarily in French. English-language or bilingual tours can usually be arranged with advance notice when booking through the tourist office.
Is the tidal flat walk accessible for all mobility levels?
The walk across the tidal flats involves uneven, wet ground and requires basic walking ability in rubber boots. Visitors with limited mobility should contact the farm in advance to discuss alternative access options.
When is oyster season at Courseulles?
Oysters are farmed year-round but guided tours run April through October. Norman oysters are considered at their best from September through April, when cooler water temperatures concentrate flavour.
Can visitors purchase oysters to take home?
Yes, all farms at the harbour sell fresh oysters directly to visitors at wholesale prices, typically €6–€10 per dozen depending on size and species.
