Perfect timing meant we arrived in Bankfoot one minute before the bus to take us home.
This walk begins in Birnam, following the Birnam Glen path up to just beyond Balhomish, then taking a left off into the fields leading into Glen Garr - a very old droving right of way. After you arrive at Upper Obney, follow the minor road into Bankfoot. If you've got your timing right, you can wait at the bus stop by the school for the bus to take you back to Birnam.
The alternative of course is to take the bus to Bankfoot from Perth, walk across to Birnam and from there the bus back to Perth. A great day out either way, with options for food and drink both in Bankfoot and Birnam!
