Causeway times for St Michael's Mount

Whether it’s a sheen of sunlight on wet sand as the tide pulls back, or the waves splashing against the harbour wall – the Mount’s surroundings change with the tides. Which means the ways you can get here change too.

Public Notice

WINTER OPENING 2019

4 November - 18 December, 10.30 - 16.00 (Mon, Tues, and Weds ONLY - Guided Castle Tours ONLY at 10.30, 11.30, 12.30, 13.30, 14.30)

29 December - 31 December, 10.30 - 16.00 (Freeflow)

At low tide access to the island is via the causeway. Setting out from Marazion Beach, it takes just minutes to walk across the ancient cobbled causeway that stretches from the mainland to the island. 

Please use our handy causeway search to look up when the causeway will be open on the day of your visit. You will be able to search for all 2019 dates. 

During April - October, regular ferry boats depart from three landing points on the mainland. Our mainland guides in the car parks will be able to advise on which landing point the boats will be departing from. One way fares are £2.00 for adults and £1.00 for children.

Being a tidal island, life on the island is often dictated by the tide. To find out more information about how the tides work - Island Life: Josh Sedgeman & The Tides.
