Boating notice: Tuesday 17 and Wednesday 18 March

The sea state forecast for today and tomorrow (17/03/2026 & 18/03/2026) is too rough for the ferry boats to operate.

St Michael’s Mount castle and village will remain open while the causeway is uncovered by the sea. The Steward’s House Art Gallery, Barge House Visitor Centre, Island Café, Harbour Loft Restaurant, Mount Shop and Island Shop remain open during this time.

Adjusted opening times

17/03/2026: Island - 09:45 to 12:00. Last Castle admissions - 10:45

18/03/2026: Island - 09:45 to 13:00. Last Castle admissions - 11:45

All unused tickets that have been booked for today and tomorrow will be automatically cancelled and refunded on Thursday, and we expect monies to be returned to the accounts from which payments were made within 5-7 business days.

We are sorry if this means you cannot visit. We are a tidal island that is governed by the forces of nature and sometimes those elements work against us.

We hope to be able to welcome you onto St Michael’s Mount soon.

Warmest wishes,

The St Michael's Mount Team
