The minor road beyond the Glen Clova Hotel ends at a Forestry Commission car park at Glen Doll with a ranger centre and picnic area, which is the trailhead for a number of strenuous walks through the hills to the north.
Jock's Road is an ancient footpath that was much used by cattle drovers, soldiers, smugglers and shepherds in the 18th and 19th centuries; 700 Jacobite soldiers passed this way during their retreat in 1746, en route to defeat at Culloden. From the car park the path strikes west along Glen Doll, then north across a high plateau (900m) before descending steeply into Glen Callater and on to Braemar (15 miles; allow five to seven hours). The route is hard going and should not be attempted in winter; you'll need OS 1:50,000 maps numbers 43 and 44.
An easier walk leads from Glen Doll car park to Corrie Fee, a spectacular glacial hollow in the edge of the mountain plateau (4.5-mile round trip, waymarked).
