The spring tides in la Manche: a spectacular show!
The 2026 programme, practical information and activity suggestions
The spring tides are an exceptional event that you can watch at different times of the year during the full moon. The sea comes and goes with the tides, covering and uncovering the shoreline, with panoramas and landscapes that change every six hours. La Manche has the biggest tides in Europe: we talk of spring tides when the coefficient is higher than 90. Prepare for a magical moment as Mont Saint-Michel becomes an island again for a few hours. Tide times, activity suggestions and practical information: we’ll tell you everything you need to know to enjoy the show in la Manche.

WHERE TO WATCH THE SPRING TIDES
The coast of la Manche changes with the tides. On the islands, by the lighthouses, along the tidal inlets or on the seaside promenades: discover the best viewpoints to enjoy the magic of the spring tides!
What to do during the spring tides: our suggestions!
WATCH AS MONT SAINT-MICHEL BECOMES AN ISLAND AGAIN
During the spring tides in the Bay of Mont Saint-Michel, the sea goes out 15 km and comes back in very quickly. When the tidal coefficient is greater than 110, the water comes right up to the ramparts and the village is cut off from the mainland for a few hours. You can watch the show from the footbridge or from inside the village for a panoramic view of the bay.
Bonus: Dare to cross the bay, but only with a guide
Although crossing the bay of Mont Saint-Michel is an unforgettable experience, it can also be dangerous. Certified expert guides, who know everything there is to know about this shifting environment, are available to take you across the sands.

Explore La Vanlée tidal inlet by paddle board or kayak
The Manche is renowned for its eight tidal inlets, estuaries where freshwater meets saltwater. These inlets are found all along the west coast. The sailing school in Bréhal offers trips accompanied by a guide to discover La Vanlée inlet by kayak or paddle board. This unique natural site fills with water during the spring tides, providing the opportunity to discover the place known as the “edge of the world” from the sea.
Kayaking in la Manche
Go shellfish gathering
At low tide, the coast of la Manche reveals vast natural expanses that are home to a host of different shellfish. This is the ideal time to go shellfish gathering. Use sustainable fishing techniques and regulatory gauges, as well as common sense (putting stones back in place, respecting regulations, only fishing what you need, etc.) to ensure you protect this natural environment and its diversity.

Watch the spring tides in a musical setting at the Traversées Tatihou festival
Organised during the spring tides in August, this festival has an eclectic lineup of world music. To attend the concerts, you walk across the sand at low tide from Saint-Vaast-la-Hougue to Tatihou Island. A laid-back atmosphere, an idyllic setting, and concerts organised according to the tide times all make the Traversées Tatihou festival a unique event!
Admire the show during the spring tides
The coast of la Manche changes appearance with the tides. On the islands, near the lighthouses, along the tidal inlets or on the seafront promenades, discover the most beautiful viewpoints to enjoy the magic of the spring tides!
Watch the mascaret
The mascaret is a tidal bore that forms with the incoming tide and gets bigger as it approaches the mouth of the Sée and Sélune rivers. You can watch this event from the Pointe du Grouin du Sud, and you might see experienced surfers and kayakers riding the wave.
What are the spring tides?
The sun lines up with the moon
Every day, the sea level varies according to the universal phenomenon of the tides. Depending on the position of the moon and the sun relative to the earth, the tidal range differs. During a full moon, the pull is so strong that it produces a spring tide. A spring tide occurs when the tidal coefficient is greater than 90.
During the spring tides, the tidal range, defined as the difference in height between high tide and low tide, can be as much as 13 m in the Bay of Mont Saint-Michel, making it the greatest tidal range in Europe! The biggest spring tides in the world are found in Canada, in the Bay of Fundy, with a tidal range of up to 16 metres.
Equinox tides and supertides
The biggest tides occur roughly every six months, close to each equinox. This phenomenon is seen in March (spring equinox) and September (autumn equinox). The tidal coefficients are then very high, often exceeding 110.
A supertide, or “tide of the century”, is when the very highest tidal coefficients are reached, in other words 119 or 120. Contrary to its name, this incredible event actually takes place only every 18 years, when the earth, the moon and the sun are in perfect alignment. The last supertide occurred in March 2015, and the next ones will be in 2033, then in 2051.
Although these special tide events are popular with spectators as well as with shellfish gatherers, because the sea goes out a very long way, they can also be dangerous. Since the sea level is higher than usual, the risks of being cut off by the tide and of local coastal flooding are very high, especially in poor weather conditions (wind, low pressure). Be careful and pay attention to the local news.
