Glenan Bay is around the coast from the ferry terminal at Portavadie, and is accessed by clearly marked footpaths through Glenan Wood. You can follow the forest path there and come back via the coastal path. Both lead you through beautiful native oak woodland which, in Springtime, is thickly carpeted with bluebells.
Glenan is a wild, pebbly bay with sand further out, sheltered to the South East by the islet and isthmus of Eilean na Beithe, and to the North West, by the headland.
If you walk beyond Glenan Bay, past the mouth of a small river and along to Buck Bay, you’ll find a lovely swimming spot with white sand and a rocky outcrop for jumping off. There’s lots of driftwood here too, so you can light a wee campfire and make yourself post-dip cup of coffee.
It’s a fair walk to get to Buck Bay; give yourself an hour or so to get there, in the knowledge that it's worth the effort.
On the way back to Portavadie, why not take a detour to explore the abandoned village of Glenan.
