Beinn Tarsuinn at 937m is a Munro on the Fisherfield Six round in the remote wilderness of the Fisherfield Forest in Wester Ross. at sort of half way round the walk, many walkers feel this is more remote tha A' Mhaighdean which seems to carry the status of most remote Muro.
To the north west of Beinn tarsuinn there is a curious flat topped subsiduary summit of Suidheachan Fhinn which at 867m doesn't qualify as a Munro Top. It has impressive crags on all sides.
Beinn Tarsuinn is an impressive viewpoint, both nearby to Mullach Coire Mhic Fhearchair, A'Mhaighdean and Ruadh Stac Mòr but also across the deep and dark Lochan Fada towards the Munro Slioch and the long Corbett ridge of Beinn Làir.
