St Michael’s Mount is a tidal island, connected to the mainland by an ancient, cobbled causeway.

At high tide, the sea covers the causeway and the Mount is inaccessible on foot; at low tide, the causeway is revealed and visitors can stroll across to explore the island.

The causeway is open for around four hours each day, depending on the tides and weather conditions. Our ticketing system is aligned to the causeway times, so you’ll only be able to book ‘walking’ tickets when the causeway is uncovered.

We suggest that you allow around 15 minutes to walk across the causeway to our first checkpoint, which is at the base of the island. We don’t restrict the time that you can stay on the island, but suggest that you allow at least 3 hours to visit the castle, shops and cafes.

As the only way onto and off the island during winter is by causeway, if you're visiting before 1st April we recommend checking our causeway times (below) and opening hours to plan ahead for when you would like to leave the island again.

From 1st April to 31st October, ferryboats will also run to take visitors across to the island at times when the tide covers the causeway. If you're booking a ticket in advance for this period, your ticket will clearly show whether you can cross by foot or by boat.
