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.

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 2018 dates. 

During the winter months, the St Michael amphicraft is the mode of transport at high tide on days that the castle is open - please see our Winter Opening Times for details. The amphicraft departs from the slipway in Marazion Car Park. One way fares are £3.00 for adults and £1.50 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.
