The iconic St Michael’s Mount rises dramatically from the waters of Mount’s Bay, just off the shore of Marazion. A medieval castle and church crown this tidal island, and a small community still lives here today. The Mount is part of the National Trust estate but is also home to the St Aubyn family, giving it a unique blend of private residence, working harbour and visitor attraction. Here’s everything you need to plan your visit.
Why St Michael’s Mount Is So Special
-
Unbridged tidal island – The Mount sits a few hundred metres offshore. At low tide a cobbled causeway, built in 1425, appears from beneath the waves and allows visitors to walk across to the island. This ancient pathway is only exposed for about four hours each day, so timing your visit is crucial.
-
Living history – St Michael’s Mount boasts a medieval castle, church and village. It has been a site of pilgrimage and legend for centuries, and Marazion itself claims to be the oldest chartered town in Cornwall, granted a charter by Henry III in 1257. Stories even suggest that the island was a prehistoric trading post known as Ictis’.
-
Spectacular setting – When the tide is high, the Mount is cut off from the mainland by turquoise waters. From Marazion Beach you’ll enjoy panoramic views of Mount’s Bay and can watch wind‑ and kite‑surfers skimming across the bay. Wildlife such as seals, dolphins and basking sharks are sometimes spotted, and birdlife is abundant.
Planning Your Visit
Check the tides – Since the causeway is only exposed for a limited window, consult our tide‑tracker before you go. Arriving too early or too late means you’ll need to catch a boat, and boat services may be weather‑dependent. Also keep an eye on our water‑guide for information on bathing water quality.
Tickets and opening times – Access to the island is free when the causeway is open, but there are separate tickets for the castle and gardens. These often sell out in high season, so pre‑booking is recommended. Note that the gardens are typically open from spring to autumn.
Best times to visit – Spring and summer (April to September) offer the most frequent causeway crossings, warmer weather and garden openings Autumn brings dramatic seas and quieter days, while winter’s shorter daylight makes timing the causeway crossing more challenging.
Getting There
-
By foot – Walk across the 400‑metre causeway at low tide. Wear sturdy shoes; the granite blocks can be slippery.
-
By boat – Small passenger boats operate when the tide covers the causeway (typically an hour or two on either side of high tide).
-
By car – Marazion is reached via the A394 from Penzance and Helston. Park in the long‑stay or overflow car parks at Folly Fields; from there it’s a short stroll to the causeway.
-
By public transport – Buses from Penzance, Helston and St Ives stop in Marazion. Penzance’s train station is about 3 miles away.
Tip: For a scenic approach, walk the coastal path from Penzance to Marazion. It’s a flat, wheelchair‑ and buggy‑friendly route with uninterrupted views over Mount’s Bay.
Things to See and Do on the Mount
-
Explore the castle – Wander through the medieval state rooms, see armour and historic artefacts, and enjoy sweeping views over the bay. Interpretive panels tell the story of the St Aubyn family and the island’s many legends.
-
Visit the gardens – The Mount’s subtropical terraces cling to steep cliffs. Rare plants from the Mediterranean, Canary Islands and South Africa thrive in this mild micro‑climate.
-
Stroll through the village – Discover the harbour, chapel and quaint cottages. Stop by the island café for Cornish cream tea with panoramic views.
-
Learn the legends – According to Cornish folklore, St Michael’s Mount was once linked to the mainland by a forest; storms in 2014 uncovered ancient tree stumps on the beach. The Mount is also said to have been a site of miracles, and its old Cornish name Karrek Loos yn Koos means “hoar rock in woodland”.
Practical Tips and Where to Stay
-
Footwear and mobility – The climb to the castle is steep and uneven. Wear sensible shoes, and be prepared for some steps. Unfortunately wheelchairs and pushchairs cannot reach the castle; however, the harbour and village are accessible.

Food and facilities – There’s a café and gift shop on the island, but many visitors opt to bring a picnic or return to Marazion for lunch. Check out our places to eat guide for cafés, pubs and restaurants overlooking the bay.
