How to visit St Michael’s Mount: Cornwall’s best island

St Michael’s Mount is one of the best places to visit in Cornwall. With a historic castle and terraced gardens located on their own tidal island, this National Trust property draws in crowds every day. 

If you’re planning to visit this castle, here is all the information that you’ll need! 

About St Michael’s Mount

St Micheal's Mount Castle

The National Trust owned St Michael’s Mount is one of the most popular tourist attractions in Cornwall, and for a good reason. 

It is a historic castle and walled gardens located on its own tidal island. St Michael’s Mount has been a place of spiritual pilgrimage since ancient times, and its Medieval castle, one of the best in Cornwall, dates back to the 12th century. 

There is nowadays a vibrant island community, and the same family has owned the castle for centuries. 

St Michael’s Mount History

Historical interior of St Michael's Mount

St Michael’s Mount has a fascinating past. The natural island has been steeped in history and legend since prehistoric times, with the Archangel Michael alleged to appear there to warn fishermen of danger. 

This caused it to become a place of religious respect and, eventually, pilgrimage. In the 11th century, the island was in possession of the owners of its sister Abbey, Mont St Michel, in Normandy. 

St Michael’s Mount castle was built in the 12th century, and it mimics Mont St Michel. During the Medieval period, the Wars of the Roses and in the Civil War, it was a site of conflict. The cannons at St Michael’s Mount also warned London of the approaching Spanish Armada!

John St Aubyn was anointed captain of St Michael’s Mount in the Civil War, and the same family has occupied the castle since. 

Nowadays, the family and National Trust have joint ownership of the island. There is a close-knit island community, but it is open every day except Christmas. The gardens are closed on Sundays.

Where do I buy St Michael’s Mount tickets?

You can purchase St Michael’s Mount tickets on the National Trust website. If you are a National Trust member, you will also need to reserve your ticket online, and if you cannot walk across the causeway, you will need to pay for the return boat ticket.

You can book tickets for just the castle or garden, or buy combi tickets for both. Ticket prices are:

  • Adults: £14 for the castle only, £10 for the gardens only, and £24 for a combi ticket for both.
  • Children: £7 for the castle only, £6 for the gardens only, and £13 for a combi ticket.

If you cannot walk across the causeway, you will need to pay an additional £2.50 each way for the boat ticket. You can buy the ticket from Marazion to St Michael’s Mount online when you purchase or reserve your ticket online. For the return journey, you can purchase non-timed tickets in the shop or cafe on the island.

If you don’t want to pay for a combi ticket, I recommend buying a castle ticket. This will enable you to see the castle and grounds, but not the gardens. The gardens are lovely, but you can see a lot more just with the castle ticket!
