Beinn a' Chuallaich is a sizeable and extensive hill which can seem quite inconspicuous when viewed from certain places, especially from the south. This is mainly because of the close proximity of the more eye catching and higher Schiehallion which lies seven km to the SE across Dunalastair Water and dominates Strath Tummel. However Beinn a' Chuallaich is well seen from the head of Glen Errochty where it shows its long NE ridge and its craggy eastern corrie. The hill reaches a height of 892 metres (2926 feet) and qualifies as a Corbett and a Marilyn.
