From Toowoomba, follow signs which take you north out of the city on the New England Highway towards Crows Nest. On reaching Highfields, (a little over 4 k from Blue Mountain Heights), turn left at the traffic lights into Cawdor Road. After approx. 1.6k, turn left into Cawdor Drive, then after approx. 2.2k, turn right into Franke Road. Continue off the end of the bitumen for several hundred metres. The dirt road is suitable for ordinary 2-wheel drive vehicles and there is room to park on the other side of the Scrub.
