Maol Domhnaich [Muldoanich]
Maol Domhnaich, anglicised as Muldoanich, is a tiny uninhabited island in the NL 689 grid square south-east of Vatersay. The 154m hill that gives the island its outline is a serious objective only because there is no scheduled access — a charter sail and a short scramble are the price of admission.

Standard route
coastal grass 60% · heather patches 25% · rocky summit 15%
After being landed by charter boat from Castlebay, climb directly from any of the boulder beaches on the north side. Steep grass and gneiss steps lead to a small grassy summit with all-round sea views. An hour of walking once ashore.
Terrain
Short coastal turf merges into heather and broken gneiss as you climb. Sea-cliff edges drop on the south and west sides and require care, especially in wind.
In winter
Boat access is rarely available between October and March, so this is a summer-only objective. Even then, swell often prevents safe landing on the steep northern shore.

Before you go
Hillwalking carries real risk and the responsibility for any day on the hill is yours. Conditions in Scotland change fast and can differ sharply from the forecast — check the weather and the ground before you commit, turn back when the day stops working, and carry map and compass with the ability to use them rather than relying on a phone.
Mountain forecasts: MWIS and the Met Office mountain forecast. Access rights and responsibilities are set out in the Scottish Outdoor Access Code.
We check what we publish, but we cannot check the route on the day you walk it. Nothing here is a substitute for your own judgement.
