Park across the street from the Gold Hill Road, which is located along State Highway 150 43 miles northeast of Kamas or 35 miles south of Evanston.
This is the old access, but a shorter route is now available.
Access to the trail is also available by going down Christmas Meadows Road (057) off of Mirror Lake Highway (Route 150)for one mile then turning right onto the oil exploration road. You may park by the gate (DO NOT BLOCK THE GATE) and continue south down the road, where it will tie into the trail.
The trail to Hell Hole Lake is known as Main Fork Stillwater Trail on USDA Forest Service maps and you can now drive to the below trail turnoff.
This is the easiest way up Kletting and A-1 peaks. This once was one of my favorite basins in the Rockies. Sadly, in the mid 1990’s a conspicuous oil exploration road was ripped through the area adjacent to the wilderness area. At the time (1996), it seemed the oil company made no efforts at all to lessen the impact of the road, but it's better now.
From the trailhead, follow the old 4wd road east. Apparently the resident beaver did not like the added vehicle noise, and dammed the creek, flooding the road in several places. Score 1 for Mother Nature. Continue along the old road/trail through the forest. Eventually, you will reach the fairly new (1996) oil exploration road and chain-link fence. Turn right and follow the road south along Main Fork Creek. Watch carefully for the trail off to the left that parallels the road a ways before leaving it. Follow the trail. The trail leads you to Hell Hole Lake, which is in a beautiful setting with Kletting and A-1 peaks towering above. There are good campsites around the lake.
To reach the summit of Kletting Peak, head south to the base of the rocky ridge, aiming for the saddle between Kletting and A-1 peaks. Climb through the boulders up to the saddle. From the saddle, boulder-hop west to the summit. You might as well climb A-1 Peak on the same trip since they are both near each other.
A good pair of boots is needed.
