St Michael's Mount rises from Mount's Bay off Marazion, a tidal island crowned by a medieval church and castle dating from the 12th century and still home to the St Aubyn family. At low tide you walk over on the causeway; when the tide is in, a short boat trip lands you at the harbour. Room guides explain the castle's collection, the roof terraces show why it made a strong defensive position, and the subtropical terraced garden clings to the cliff below, weeded by gardeners on abseil ropes. Reviewers say the views from the top are worth every step and rate the harbour and gardens as the highlights. Tips from visitors: book tickets in advance through the Mount's own website and check tide times; the causeway and the path up are steep and uneven, so small children may need carrying; the garden has its own opening days, so check before you go; and parking in Marazion is chargeable, members included. Only assistance dogs are allowed on the island.
