Mayar and Driesh Circuit is a 9.6-mile loop from Glen Doll car park over two Munros, climbing through Corrie Fee and returning by Kilbo. The stored line follows the complete loop, including the short return from Driesh to the descent junction. Published route figures range from about 9 to 9.5 miles; this mapped line measures about 9.6. Allow around six hours and roughly 835 metres of ascent. The payoff is a striking glacial bowl, a waterfall and two broad, open summits.
This is a long mountain day rather than a stroll to the waterfall. The lower approach follows tracks and woodland paths; the upper half crosses rough, sometimes boggy open ground where the line becomes less obvious. If you only want Corrie Fee, its shorter reserve path makes a separate outing without either summit.
