It is conveniently done taking in its neighbour, Beinn a'Chroin (942m),

and continue up its southwest bank. Assuming an anti-clockwise walk, with

the grassy north slopes of Sron Garbh. The following ridge is known as
Twistin Hill and leads eventually to a rocky knoll and the summit.
Go down the
south ridge, which becomes steeper and rockier before the level col is
gained before the rise to the summit ridge of Beinn a'Chroin. Climb the
rocky northwest end of Beinn a'Chroin, zigzagging through the crags. Beinn
a'Chroin has a 1km-long summit ridge with two tops, with the highest point
near the east end of the West Top, round about the middle of the whole
ridge (388 186).
