The 5 Main Islands on Isles of Scilly
The Isles of Scilly are around 23 miles off the Cornish coast (you can take the ferry from plastic-free Penzance). Stunningly beautiful, they look more like Caribbean islands, with white sandy beaches and clear blue seas. But don’t be fooled – this area has many shipwrecks, to show waters can be treacherous.
The islands are slightly warmer than elsewhere. And many birds like to stop here for a rest, when migrating from or to Africa. The islands are very popular with painters.
Always follow the Countryside Code, to keep all creatures safe. If at the coast, read our post on keeping dogs safe by the seaside.
One sailor stranded on an island for a few days was shocked to find dead marine wildlife, many due to oil and litter. This caused him to found Clean Ocean Sailing, a team of volunteers that remove plastic waste from the coast in all of Cornwall.

A Quick Guide to the Main 5 Islands
St Mary’s is both the heart and busiest corner of Scilly. Its lively harbour at Hugh Town greets nearly all visitors. Cobbled streets wind between cafés, galleries, and old stone buildings. Car-free footpaths lead out to sandy beaches and craggy headlands.
Tresco’s reputation springs from its sub-tropical Abbey Garden. Rare palms, exotic blooms, and succulents layer across terraces—all warmed by Scilly’s gentle climate.
Red squirrels, absent from most of England, make this island their home (there’s no need to cull grey squirrels with proper habitats).
St Martin’s brings together some of Britain’s clearest waters and softest sands. Low-tide reveals wide expanses, while steep dunes and heathered cliffs shelter wildflowers and butterflies.
With only a handful of shops and a single pub, it keeps things simple. The island has become known for its vineyard and the only flower farm in Scilly open to visitors.
St Agnes is smallest of the main inhabited islands, and feels the most remote. Rocky outcrops, old lighthouses, and sweeping sea views create a world apart. Ancient chapels, and hidden coves make St Agnes a haven for walkers.
Bryher stands close by, just a short boat ride from Tresco, but its mood can shift in moments. One side meets the wild Atlantic in crashing surf, the other lies calm and sandy.
Tiny hamlets, scattered fields, and a single hotel give this island an ideal space, for quiet and wide coastal skies.
Home to Many of our Native Seals
Grey and harbour seals are both found here, giving birth and resting on beaches. Never play frisbee on beaches (seals get trapped in them) nor jet ski near any marine creatures. Keep dogs away and keep at least 100 metres away (if a seal is looking at you, you’re too close). Read more on how to help native seals.
