Rockface Mountain stands at the southeast end of Paul Lake facing east toward Pinantan Lake. The hike to the top of the mountain is a short one, though steep. A high clearance vehicle can go right to the trailhead, but we started back on the Pinantan – Harper Road to add some more distance. Our 13 km return hike followed backroads toward the east-facing bluffs of Rockface Mountain.
A sideroad winds up into a bowl between Harper Mountain and Rockface, then a quad track bears off northeast turning to northeast to the single track which climbs to a pass between the east and west summits of Rockface. A short flagged trail follows the ridge west to the top of the bluffs, a good stop for lunch. Views extend northeast, east, and southeast over the forested areas near Pinantan.
The cave has a large opening, but does not go back very far. It is a bit of a tricky scramble to get up into the cave, but with care it can be done.
- Follow the Paul Lake Road to Pinantan and turn right onto the Pinantan – Harper Ranch Road (go past the store)
- Follow the road to the southwest corner and turn onto the Pinantan – Harper Road
- At 0.4 km the road splits (@N50 43.428 N120 02.336). Right goes down the Hale-Vinnie Road; left heads up into the hills, the way to Rockface.
- Follow the backroad for another 1.6km ignoring minor sideroads
- At a fenced junction, turn right, crossing a cattle guard (@N50 43.071 W120 03.401)
- Follow this road for 3.2 km, ignoring minor sideroads
- At a 3 way junction (@N50 43.355 W120 05.110) take the middle fork up into the higher basin
- At 0.7 km after the junction, watch for a quad track on your right; park
- Follow the quad track for 50m, then take the left track which turns into the trail.
- To get to the cave, return back down the road to the 3 way junction and take the north fork this time.
- Follow the road for 0.7 km to a clearing (@N50 43.635 W120.04.983). Follow the trail up the shale slope to the cave which is found at the foot of the bluffs.
- Return by the same route.
