At 1849m above sea level the reward is an incredible view across Falls Creek and Bogong High Plains. A great Summer trek, this trail takes you past Sun Valley and some of Falls Creek's most popular ski runs to the base of Mt McKay. Another great feature of this hike is passing the columnar outcrop of basalt rock from which Ruined Castle draws its name.
Begin your walk at Ory's Trail (on Schuss St opposite Milch Café), following it up until you reach the large brown tank containing Falls Creek's water supply. Continue uphill along the vehicle track until it crosses onto the old Summit home trail to where the trail forks. Veer left following the trail markers until you reach Pretty Valley Road. From here head right along the road until you reach the Ruined Castle rock feature. Keep following the winding trail uphill to a vehicle track and across Pretty Valley Road before reaching the base of Mt McKay (1,872m). Follow this road up and you'll be rewarded with spectacular views across to Mt Hotham, Mt Feathertop and Mt Bogong.
