Our goal for Monday was to get to St Michael’s Mount. It’s the island rising from the ocean in the distance of this below photo.

From Penzance, it is a 3 mile walk to Marazion and then at low tide, you can walk on a causeway to the island. We took the coastal path.
Bought tickets to hike up the island to the castle which was once a priory, then later a fortress.
Now it’s just a tourist attraction. But with good views.
Back on the mainland we stopped for lunch where I tried to dry my socks which got a bit wet from walking on the beach.
Enjoyed some local crab.
Then we walked back as the tide was coming in.
What with a dead end detour and a side trip for some wine, we walked over 25 kms.
