Leave the City Bypass at the Lothianburn Junction and head south in the direction of Biggar on the A702. At the fork, take the middle road A701 direction Peebles. Carry on around the large bends for approximately 3/4 of a mile.
Go past the cottages on the right and past a single track to the left sign posted to Old Pentland. Immediately after this turn off and opposite the bus stop take a left hand turn up through an avenue of trees. Carry on up into the farm yard and park. The office is at the back of the large house.
