Beinn Fhionnlaidh is a truly remote Munro only really accessed from neighbouring Munro Carn Eige. Beinn Fhionnlaidh rises from the southern shores of Loch Mullardoch and sits at the end of a long curved ridge taking in several other Munros. The summit is bitten into on all sides by a collection of small corries giving rise to a stretched out summit plateau running S-N, with the actual summit at the northern end. The east face of mountain has several crags and is best avoided. Beinn Fhionnlaidh has only one summit ridge running south to Bealach Beag before leading to neighbouring Munro Carn Eige.
From the summit there are great views to be had down the length of Loch Mullardoch and to the group of Munros to the north of the loch. From Beinn Fhionnlaidh you can really appreciate the remoteness of these Glen Affric Munros.
