Led by Philippe Jaloin, Grandeur Nature offers walking trips across the tidal flats of Mont-Saint-Michel Bay with an accredited nature guide from the area.
Two ways to discover the bay
The two-hour discovery walk approaches the quicksand around the Mont and focuses on exploring this distinctive environment. For those wanting a longer outing, the guide also offers an approximately three-hour crossing towards Tombelaine, including river crossings under his supervision.
What to know before setting out
The 2026 programme runs from March to October, with prices advertised from €15. The meeting point and instructions depend on the tides, and visitors must follow the guide's directions. The shorter option is presented as suitable for everyone, while the Tombelaine crossing requires more effort.
