How to Get to Muckle Green Holm #

Muckle Green Holm is a small, uninhabited island in Orkney with no public transport or scheduled ferry service. It can only be reached by private boat or charter from the Orkney Mainland (for example from Kirkwall or other local harbours). Landing is tide- and weather-dependent, so arrange passage with an experienced local skipper or hire a charter from an Orkney marina.

Tips for Visiting Muckle Green Holm #

  • Muckle Green Holm is uninhabited and has no public ferry service, so landings require a private boat or charter-only attempt with an experienced local skipper.
  • The island is important for seabirds; avoid disturbing nesting areas and plan visits outside the main breeding season, keeping noise and movement to a minimum.
  • Orkney weather and sea conditions change quickly-check a local forecast and tidal information before you go and be prepared to abort a landing if winds or swell increase.
