Beinn Tarsuinn lies on the N shore of Loch Fada opposite Slioch. The incline of the S slopes vary greatly from easy and boggy to steep and craggy. The SSW ridge in particular has a steep craggy SW face but to the E are easy slopes from the path is the normal ascent route via the track from Incheril. The slopes are much steeper and craggy N of the summit and on the narrow curving NW ridge leading to Mullach Coire Mhic Fhearchair via Meall Garbh.
Long hard route to three remote peaks. The boulder strewn tops make for slow progress, but little scrambling required. Cycling will reduce the time required.
