Just as touristy as everyone says it is, but still magical. We drove to it but when I visit again I want to walk to it over the sand flats from the mainland (with a guide, obviously!). I’d also love to stay on the Mont for a night. The tide does move quickly but definitely not at the speed of “galloping horses”, which was slightly disappointing – check the tidal timetables and try to visit when the tide will be at its highest.
