We started the trail at about 11:30 in the morning and reached the top in about an hour and a half. The trail is rocky but it doesn't have any major obstacles or areas of difficulty.
The most difficult part seemed to be finding our way. It would probably be impossible to get lost as most of the trails seem to end up in the same area.
There were a couple of rocky hills that were fun, and the end of the trail got steeper. We reached the parking area and it looked like the trail may have gone through only a few years ago. It's gated now, allowing horses, hikers and ATVs. There were quite a few vehicles parked up there and it looked like there were horses there frequently.
It was a nice trail, though short. We had lunch at the top and then took Kawuneeche Road down just to where we saw the sign for South Supply Creek. We took that (and saw some nice views of the Lakes) and ended up at North Supply Creek again. We took that down to the first parking area.
This is a really nice trail. You could wander around in the trails up there all weekend.
