Beinn Fhionnlaidh is a very inaccessible mountain, some distance from the nearest road, so usually involves a long walk in. One route is to start from the end of
Loch Beinn a' Mheadhoin in
Glen Affric, then follow a path up Gleann nam Fiadh. From there, it is necessary to climb up and over the east ridge of
Càrn Eige, before following its north ridge to Beinn Fhionnlaidh, via Bealach Beag. Another approach is from the west, starting from the end of the road at
Killilan. From there follow a track along Glen Elchaig to Iron Lodge, then a path to the western end of Loch Mullardoch, at the foot of Beinn Fhionnlaidh. An easier alternative is to travel by boat along Loch Mullardoch to the foot of Beinn Fhionnlaidh, then climb straight up. ==References==
