Make your journey across the sea: travel to St Michael’s Mount by boat.
St Michael’s Mount is a tidal island connected to the mainland by a causeway (a raised cobbled walkway on the sea bed). When the tide is high and water covers the causeway, you can also cross over by boat.
Getting to St Michael’s Mount by boat is a special and memorable experience. If this is something you would like to do then you need to book a ticket for the castle or garden when the causeway is closed and the boats are operating. Our booking system will also prompt you when a boat ticket is required. You can’t travel by boat when the causeway is open.
Boat tickets are not available individually and you cannot access the island by boat unless you have a ticket to the castle and/or garden. Boat crossings take approximately ten minutes and you must arrive at the boat landing 30 minutes before your timed ticket to the castle and/or garden.
National Trust Members are required to pay the boat fare at the point of booking a castle and/or garden ticket.
How to find our boats
Our boats will depart from the mainland from one of three landing points depending on the height of the tide – Chapel Rock, Gwelva and Top Tieb (see map). Return boats will run from the island harbour. You will be directed to your boat landing by our guides on the day.
