Close to Pitlochry, there are the hills north from Glen Tilt. Depending on your overnight plans, about 10 miles/day could get you from the Old Bridge of Tilt up to the bothy at Allt Scheicheachan, then over Beinn Dearg to Feith Uaine (the Tarf Hotel) and finally back over Carn a'Chlamain to the carpark again.
From the deer stalking info on WH, the main paths to the Munros (Beinn Dearg and Carn a'Chlamain) are fine, though it'd be best to check further about the route between them. I walked this in a dry summer a couple of years ago (and included Beinn Mheadhonach plus a couple of other Munros), though that'd make for at least one long day, or might need an extra day in the middle of the trip.
Keeping to that outline route should minimise burn crossings, though you'd have some trackless and likely boggy ground between BD and the Tarf Hotel.
