The tides set the pace for life on the coast. They transform the landscape, revealing the foreshore and providing the opportunity for a wide range of activities, such as fishing on foot or walking on the rocks. Before enjoying the beaches, it’s essential to check the tide times: it’s simple, practical and guarantees a safe outing!

The tides, what is it?

The tides are the result of the attraction exerted by the Moon and the Sun on the oceans. Every day, there are two high tides and two low tides, with times that change daily.

The famous“tidal coefficient” indicates the amplitude of the tide: the higher the coefficient, the more the sea withdraws and the wider the foreshore.

On the Guérande peninsula, the tidal range is high enough to reveal a large area of foreshore at low tide, which is why our area is so popular with anglers!

You can ask for the tide times at any of our Tourist Office offices.

Alternatively, you can find them below!

Fishing on foot, the pleasure of high tides

Fishing on foot is one of the emblematic activities of the Guérande peninsula, practised at high tide on the beaches, rocks and mud flats. Our coastline offers a wide variety of spots where you can find cockles, clams, periwinkles, crabs and prawns. The activity is closely linked to the tides and the weather, so it’s important to check the timetable before setting off and any current bans.

The regulations also impose minimum catch sizes and limit quantities in order to preserve the natural environment. The Tourist Office encourages responsible fishing to protect this fragile ecosystem.
