Découverte de la Baie du Mont-Saint-Michel
Découverte de la Baie is a guiding company in Genêts, on the Norman shore of the bay, that has led groups across the sand since 1994. All its guides hold the prefecture's accreditation as a Mont-Saint-Michel bay guide, or are training under the responsibility of an accredited one: it is what is needed to cross the bay safely, because the tide comes in fast, there is quicksand and the rivers change course.
What they do
From late March to early November they organise the long crossings from the Bec d'Andaine or Saint-Léonard to the mount: return on foot, about 14 km and six hours (€23 adults, €15 ages 3 to 14), or there on foot and back by shuttle and bus (€33 and €25). All year they run circuits to the island of Tombelaine (€20 and €13) and short walks of about two hours at the foot of the mount: the walk round the mount, the sunset walk and the rising-tide walk with the tidal bore (€17 and €12), and one of an hour and a half on the quicksand (€15 and €11). Under-3s do not pay.
How it works
It is wise to book on its website, because groups are limited; with a reservation, the guide waits for you fifteen minutes before at the departure point. Without a reservation, you can turn up in the half hour beforehand and pay the guide if places remain. From April to October you walk barefoot and in shorts; from November to March, in boots or neoprene booties and warm clothes. Dogs may go on a lead, but not on outings with a shuttle or bus. The activities are not for pregnant women or people with heart, breathing or joint problems.
