On our way back to Farnham, we checked the tide tables and then headed to St. Michael's Mount. To add to the excitement of visiting a super old structure (the church was built in 1144)... the island is reachable by footpath for just a few hours a day during low tide.
Cary and I have done our fair share of river fording in the wild, and had no problem crossing while the pathway was still covered, a fabulous way to beat the crowds! The views were amazing, but I think my favorite part of touring around the castle were the old maps. It's one thing to hear a place is very old, but to look at a document created in 1576, with Mousehole and Lands End labeled... really made me think about how long these places have existed.
