Walking Guide

The Isles of Scilly are one of the finest walking destinations in the UK. With over 140 islands and rocky islets, dramatic granite headlands, secluded beaches, flower-filled lanes and miles of coastal paths, every walk offers something different.

Unlike many walking destinations, the islands have very little traffic, allowing you to explore at your own pace while enjoying uninterrupted sea views, abundant wildlife and some of Britain's cleanest air.

Whether you're looking for a gentle family stroll or a full-day coastal adventure, there's a walk to suit everyone.

Every island has its own character, making island hopping on foot one of the highlights of any visit.

Walking Between Islands

One of the joys of walking in Scilly is that each inhabited island offers a completely different experience. Inter-island boats operate during the main visitor season, making it easy to combine several walks during your holiday.

Many visitors spend one day exploring each island — St Mary's, Tresco, Bryher, St Martin's and St Agnes — which allows you to experience the unique landscapes of each in turn.

  • Keeping to established paths where practical.
  • Closing gates behind you.
  • Taking litter home.
  • Respecting farmland.
  • Keeping dogs under control around livestock and nesting birds.
  • Leaving wildflowers and wildlife undisturbed.
