Tam McArthur Rim Gear Checklist

Tam McArthur Rim is a short, exposed climb from Three Creek Lake to a cliff-edge viewpoint over the Three Sisters and Broken Top. Writers agree on the same few items: sunscreen, enough water because the plateau has none, and a wind layer for the open rim. Beyond the official end, the route to Broken Hand and No Name Lake gets faint, with snow patches that some hikers cross in traction. Sources disagree about when the road and trail open, so dates below are tied to the year each person went.

What shapes your gear on Tam McArthur Rim

Permit and timing
A day-use Central Cascades Wilderness Permit is required at this trailhead from June 15 to October 15, at $1 per person for each outing. A 2024 Bulletin writer reserved 10 days ahead, and permits are also released 2 days before the trip.

Length and climb
The Bulletin gives 5.3 miles round trip and about 1,400 feet of gain to a viewpoint at 7,730 feet, usually under three hours. Rooted n Roaming says 5 miles and 1,250 feet, and the book excerpt on Off the Beaten Trail puts the official end of the trail at The Prow, 2.8 miles from the trailhead at 7,700 feet.

When the road and trail open
Recreation.gov says snowpack can keep vehicles out until mid or late June, and that Forest Service Road 16 is bumpy in places yet passable for most vehicles once the snow is gone. The Oregon Hikers field guide says it is usually August before the snow melts enough to reach the trailhead and complete the trip. Rooted n Roaming puts the best window at mid-July to mid-October, with snow on the trail through July.

Parking and the lack of services
A July 2020 hiker parked on the road shoulder because there is no lot at the Broken Hand access, found no restrooms and no fee box, and got no cell signal at the trailhead. Rooted n Roaming also says there is no established parking lot at the Tam McArthur Rim trailhead. A 2015 Bulletin writer parked at the Driftwood Campground lot, which was nearly full on a Wednesday morning.

Past the end of the trail
The Bulletin says a trail the agency does not maintain runs west along the rim to No Name Lake, for an 11.5 mile round trip with about 2,200 feet of climbing. A July 2020 hiker covered 10.35 miles and 1,816 feet toward Broken Hand, crossed two easy snowfields, and turned back at a large steep snowfield beyond it.
