Marilyn · Arran
Beinn Bhreac
Speckled Hill, a broad heather-and-granite dome north of Glen Rosa on Arran. From the summit ridge the famous A'Chir aretes and Cir Mhor rise dramatically to the west, offering a fine first taste of the wilder northern Arran skyline without committing to scrambling ground.
Gaelic: “mountain, peak” · Pronunciation: bine

Standard route
heather moorland 50% · rough grassland 30% · granite/schist 20%
The usual line is from Glen Rosa, taking the path up Glen Rosa and then breaking right onto the south-east ridge of the hill. Around 13km return with 700m of ascent; allow five hours and savour the seats with a view of the Saddle.
Terrain
Stalkers' path in lower Glen Rosa, then a pathless rough heather and granite ridge. The summit cap is a tumble of granite boulders — care needed if wet or snow-covered.
In winter
Snow accumulates on the upper ridge from December onwards and can be wind-slabbed. Treat as a serious hill day in winter despite the modest altitude — full kit and an early start.
