The Cabane Vauban was built in the 17th century and is named after the famous French fortification engineer Sébastien Le Prestre de Vauban, who was responsible for the design and reinforcement of numerous coastal fortifications during the reign of Louis XIV. The hut originally served as a shelter for sentries and customs officers monitoring the coast to detect smugglers or enemy ships early. While there are several similar observation points along the Normandy coast, the Cabane Vauban near Carolles is considered the most well-known and well-preserved.

The Rocher du Sard lies above the Vallée du Lude. This striking granite rock rises about 70 meters above the sea and offers a commanding view of the Bay of Mont Saint-Michel. Local legend says that the rock was a refuge for the Devil during his battle with the Archangel Michael—hence its nickname, Rocher du Diable.

Its origins date back to the 6th century, when the future Saint Leonard worked in the region. In 1087, William the Conqueror granted the fief of Vains to the Abbey of Saint-Étienne in Caen, which subsequently founded the priory. The building dates back to the 11th century and has been restored several times over the centuries. Today, the priory serves as a holiday accommodation.

The mudflat hike to Mont Saint-Michel usually starts at the Le Grouin du Sud headland near Genêts. This is the official starting point for guided tours through the bay, which lead across the mudflats to Mont Saint-Michel at low tide. The trail should only be undertaken with a certified mudflat guide, as the area is potentially dangerous due to tides, currents, and quicksand. Popular providers such as Chemins de la Baie du Mont-Saint-Michel regularly organize safe tours from Genêts.

The Route du Grouin du Sud, also known as the "Customs Officer's Path," is a 10- to 11.5-kilometer-long coastal hike near Genêts and Vains. It leads through the impressive bay of Mont Saint-Michel and offers beautiful views of the sea, Mont Saint-Michel, and the Tombelaine rock along long stretches. The route is mostly circular and takes between two and a half and three and a half hours, depending on your pace. It runs through meadows, coastal paths, and small country roads. It is unpaved in places, so sturdy footwear is recommended. A cultural highlight is the Prieuré Saint-Léonard with its historic chapel. The "Grouin du Sud" headland is particularly worth seeing; on a clear day, you can enjoy a panoramic view of the entire bay.
