Location

What’s nearby

The village around the ferry slip has a handful of cafés, places to eat and small shops within a short walk of the beach. Iona Abbey and Nunnery are a walk north through the village, on the site where St Columba founded his monastery in AD 563. For a longer outing, the walk to Dùn Ì and the north end climbs the island’s highest point and carries on to the white sand beaches at the top of the island. Boat trips to Staffa and Fingal’s Cave also run from Iona.
