About St Michael’s Mount

St Michael’s Mount is a tidal island joined to the mainland by a cobbled causeway. Each year, thousands of visitors from across the globe come for its rich history, natural beauty, subtropical gardens and, of course, iconic castle.

Access to the island is ruled by the tides. This means getting across and back is an experience in itself. You may find yourself gliding into the historic harbour on a small ferryboat. Then returning to shore across the ancient causeway, the sea lapping at its edges.

Here’s some ideas to inspire you for your visit. Click on the links below for more details. Bear in mind, some parts of the island are closed in winter. Check our Winter Opening page for more details.

Explore an ancient castle

Take in sweeping views from the defensive battlements of this magnificent castle, where rows of cannons stare out to Mount’s Bay below. Inside, walk through a labyrinth of corridors to see how occupants lived, ate, prayed and did battle over the centuries. Find out more.

Step into the past

History comes in waves here. Henry de la Pomeroy seized and fortified the Mount in 1193. Soldiers fired cannons at Napoleonic ships. And it has become home to fascinating artefacts along the way, including Samurai armour and a mummified cat from Egypt. Find out more.

Soak up the subtropical gardens

Built in 1887, the Garden Terraces at the rear of the castle are a plant-lover’s delight. Agave, cacti, aloe and many more subtropical species cling to the granite on a patchwork of meticulous terraces. Look up and you’ll also enjoy one of the most spectacular views of the castle, which rises out of the cliff face above you. Find out more.

Wander the harbour and village

Enjoy an atmospheric amble among the cobbled streets, cottages, stables, net lofts, and ancient harbour of St Michael’s Mount Village. This was a thriving commercial district in the 1800s and 30 people continue to live here today. Walk in the footsteps of kings, queens and pilgrims. Find out more.

Something to eat – and celebrate?

Our cafes and pop-ups offer everything from quick bites and ice creams, to proper Cornish treats such as freshly baked scones and pasties. You can also treat yourself to a sumptuous Afternoon Tea at the Harbour Loft restaurant. 

Looking after the Mount

The St Aubyn family, who have a historic connection with the Mount, and the National Trust ensure this precious island is safeguarded for future generations. Find out more about their unique relationship and the role each plays in its care.


Mouth-watering treats on the Mount

Licking ice cream off sticky fingers. Spooning jam onto freshly baked scones. Tucking into a flaky Cornish pasty. Whether it’s a summer treat or a winter warmer, our cafes and pop-ups cater for all tastes.

From seafood landed fresh from the bay, to locally produced wines, Cornish teas and veggies grown on our doorstep, we scour the county to bring you the best local produce.

Getting here. Walking or boating?

St Michael’s Mount lies in Mount’s Bay, off the coast of Marazion. This ancient tidal island is connected to the mainland by a cobbled causeway.

When the tide is low, you can walk across. When it’s higher and the causeway is covered, you’ll need to take a boat from Marazion.

If a boat is necessary during your visit, a boat ticket banner will automatically appear during booking.

National Trust members are required to pay boat fares when booking, but not island admission fees.

Plan your visit

St Michael’s Mount is an ancient tidal island. This is part of its charm, but occasionally it can also be a part of the challenge.

How to get to the Mount

You can reach the Mount by a cobbled causeway at low tide and by boat when the causeway is covered and the tide is high. Boats run from 29 March to 31 October – they are not available in winter.

Meeting your accessibility needs

If you have young children or mobility issues, it can sometimes be tricky to get around. Please note: you can’t take a wheelchair or pushchair up to the castle.

Bad weather

Strong winds and/or rough seas can force us to close the island. Where possible, we’ll give 24 hours’ notice. We’ll let booked customers know by email and issue refunds within seven working days.

We also announce closures on our website and social media. If we don’t announce a closure, we are open.
