Walking

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 pre-booked 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.

Your ticket will clearly show whether you can cross by foot or by boat. It is important that you adhere to the time and means of crossing advised. You could be turned away from the island if you arrive too early or late.

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 allow at least 3 hours to visit the castle, shops and cafes. When you want to leave and depending on the tide, you will either walk across the causeway to the mainland or catch one of our boats. Boat tickets from the island back to the mainland, can be purchased from any of the island’s retail and food outlets and our staff will always be on hand to help.
