Tresco
Island Scilly island famed for sub-tropical Abbey Gardens
Tresco in the Isles of Scilly draws gardeners and beachgoers to the subtropical Abbey Garden, white-sand coves, birdwatching spots and inter-island boat services from St Mary’s.
Tresco is one of the inhabited islands of the Isles of Scilly, off the southwestern tip of Cornwall, England, known for its mild climate and horticultural interest. The island is most famous for the Tresco Abbey Gardens.
The gardens surround the ruins of a medieval priory and contain extensive collections of sub-tropical and exotic plants that thrive in the island’s maritime climate. Visitors come to see the gardens, coastal walks, and a small community of houses and farms.
Tresco has been developed for tourism and horticulture since the 19th century and is administered locally as part of the Isles of Scilly. The island maintains accommodation, walking paths and heritage features tied to the Abbey and its historic owners.
Geographically Tresco lies toward the western side of the Isles of Scilly, within easy boat transfer distance from St Marys, the archipelago’s main island, and is reached by ferry or private boat from the mainland.
- Transport and access: The island has been managed as a largely car-free community with boat connections to other Isles of Scilly islands.

- Tresco Abbey Gardens: Tresco Abbey Gardens - a subtropical plant garden established in the 19th century around the ruins of a priory, famous for exotic and tender species.
How to Get to Tresco #
Tresco (Isles of Scilly) is reached via St Mary’s. From Penzance (Cornwall) take the Scillonian passenger ferry (seasonal) or the Isles of Scilly Skybus helicopter to St Mary’s; from St Mary’s a short boat transfer or passenger ferry runs across to Tresco (the inter‑island crossing is brief). If you fly to St Mary’s, transfer boats meet flights; private boats and charter services are also common between the islands.
Tips for Visiting Tresco #
- Book ferry crossings and, if visiting the Abbey Gardens, garden entry in advance during summer - day-boat schedules concentrate arrivals around late morning, so an early arrival gives quieter exploration.
- Head to Tresco Abbey Garden before the day tours peak; many visitors focus on the gardens, but walking the island's quieter southern beaches or coastal paths later in the day rewards you with empty sands.
- Rent a bicycle or use the island's licensed transport to reach lesser-visited coves and the southern lighthouses; these spots are often missed by people who stay near the main quay and garden.
