Perched dramatically on its tidal island, the castle on St Michael’s Mount in Cornwall feels like something straight out of a storybook.
What began as a monastery in the 12th century later became a fortified castle and, eventually, the family home of the St Aubyns, who still live there today.
Inside, you’ll find grand halls, armour, and centuries of history packed into every corner, while outside the views across Mount’s Bay are absolutely breathtaking.
The best bit? You can either stroll across the causeway at low tide or hop on a boat when the sea covers the walkway, making the whole visit feel just that little bit magical.
What Is There?
- Long, tidal causeway (free to walk on, but watch the tide!)
- Village - people actually live there full time!
- Castle
- Garden - stunning, subtropical planting
- Gift Shop
- Gallery
- Cafe and Ice Cream
- Toilets
- Run by the National Trust
St Michael's Mount have made some changes to how they are allowing visitors onto the island. It used to be you could walk over the causeway and visit the cafe and shop without having to have tickets. Dogs also used to be welcome in these areas too. Not anymore!
Between 1st April to 30th September, you can only access the island with tickets and there is a no dogs rule. However, is still FREE to walk across to St Michael’s Mount at low tide but if you don't have tickets for The Island you will almost be frog-marched off! However, do note that the island doesn't own the causeway and it is still a right of way. You can walk it to the main entrance, and rockpool there for free.
Between October and March access to the harbour and village (not the castle and garden) is free for everyone during opening hours and you can take your dogs over.
Dogs On The Beach
Also do be aware that Marazion beach has a dog ban from 1 July to 31 August between 10 am and 6 pm and is dog-friendly outside of these hours and between 1 September and 30 June when dogs are permitted on the beach.
Car Parking
Confusingly and annoyingly, the main car park in Marazion by Folly Field is NOT owned by the National Trust. So National Trust members don't get any free parking for the Mount.
Please check the St Michael's Mount website for opening times and tickets.
