St Michael's Mount is a tidal island and historic castle off Marazion in Cornwall. Access is by boat or causeway according to the tides, with parking on the mainland.
Pet dogs can visit only during the permitted seasonal dates and only in the harbour and village. The castle, castle grounds, summit and paths, garden, gallery, shops and indoor food venues are excluded.
Dogs must remain on short leads. Check the current dog-access dates, tide times and any weather closures before travelling. Assistance dogs have wider access when the island is open.
