Boating

Make your journey across the sea: travel to and from 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.

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. Assistance dogs only.

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 and you can buy retrun boat tickets on the island. You will be directed to your boat landing by our guides on the day.

Boat fares

One way boat fare:

Forgot your boat ticket?

You must book a boat ticket(s) in advance with your castle, garden or combi ticket, if it is required. If you've already booked your ticket to visit the island, but forgot to book a boat ticket, you can still book online now. Please don't do this unless you've already booked a ticket to visit. We're sorry, but if you haven't pre-booked a boat ticket for your visit, you won't be able to board a boat on the day.

Return Boats

To paddle or not to paddle? That is the question.  If you don't fancy getting your feet wet, or you don't want to wait for the causeway to open, hop on a boat!

Return boat tickets are purchased on the day of your visit on the island, either on a smartphone or in one of our retail outlets, so there's no need to book these return tickets in advance.
