St. Michael's Mount

St Michael's Mount is almost a copy of the more famous Mont Saint-Michel, with the same characteristics: at high tide, it looks like an island, but at low tide, you see that the island is actually connected to the mainland by a huge sandy strip, and you can reach it by means of a cobbled path that was underwater just a few hours before. On the island you'll find a lovely twelfth century castle and a quaint village, and if you forget about the time and find yourself stranded, don't worry, as boats also offer access to and from the mainland.
