Mullach Buidhe
Mullach Buidhe, the yellow summit, is the high point of Scalpay, the small island off east Harris linked by bridge from Tarbert. At 161m it is one of the lowest Marilyns yet rewards visitors with intimate views of the Minch and Eilean Glas lighthouse.

Cross the Scalpay bridge and park near the school, then follow the waymarked lighthouse path before peeling off north to the summit. A pleasant two-hour outing combining moorland, paths and rocky knolls.
Terrain
Mix of waymarked path, short heather and gneiss slabs. The summit dome has bare yellow-lichened rock that gives the hill its name.
In winter
Mild but exposed to Minch storms; snow is rare. The lighthouse path is usable year round but the boggy summit ground turns greasy after rain.
