10 fascinating facts about the Isles of Scilly

Lying just 28 miles off the tip of Cornwall, the Isles of Scilly feel like another world, a cluster of stunning islands surrounded by turquoise seas and white-sand beaches. With their mild climate, fascinating history, and relaxed pace of life, they’re one of the UK’s most unique and beautiful destinations.

1. An archipelago of islands – The Isles of Scilly consist of around 140 islands, islets, and rocky outcrops, though only five are inhabited: St Mary’s, Tresco, St Martin’s, St Agnes, and Bryher.
2. Mild climate – Thanks to the Gulf Stream, the islands enjoy one of the warmest and sunniest climates in the UK, allowing subtropical plants to thrive year-round.
3. Tresco Abbey Garden – Often described as “Kew Gardens with the lid off,” this world-famous garden is home to thousands of exotic plant species from around the world.
4. Historic shipwrecks – The seas around the islands are littered with shipwrecks. The most famous was the Association, an admiral’s ship wrecked in 1707 with the loss of nearly 2,000 lives, prompting major improvements in navigation.
5. King Charles’ Castle – On Tresco, this 16th-century fort was built to defend the islands from French invasion and still offers spectacular views across the surrounding seas.
6. Wildlife haven – The Isles of Scilly are home to a wide range of wildlife, including seals, puffins, dolphins, and migratory seabirds. The uninhabited islands are key breeding grounds for many species.
7. St Mary’s Harbour – The largest of the islands, St Mary’s is the main transport hub, with ferries, planes, and boats linking the islands to mainland Cornwall and each other.
8. Crystal-clear waters – The clarity of the water around the Scillies is exceptional, often compared to the Caribbean. Snorkelling and kayaking are popular ways to explore its hidden coves and reefs.
9. Community life – Despite their remoteness, the islands have a close-knit community of around 2,000 residents who maintain a sustainable and self-reliant way of life.
10. Dark sky sanctuary – With minimal light pollution, the Isles of Scilly offer some of the best stargazing in the UK, with breathtaking views of the Milky Way on clear nights.

Remote yet welcoming, wild yet peaceful, the Isles of Scilly capture the very best of island life, a rare place where natural beauty, history, and tranquillity come together in perfect harmony.
