Tinkham Peak is located about 6 miles south of Snoqualmie Pass and about 1 mile southeast of Silver Peak. Since it's short in stature and located just off the PCT, Tinkham Peak has the potential to be popular. However, it is lesser known than most other peaks in the Snoqualmie Pass area and there isn't much information to be found on it, so it remains less traveled.

As mentioned, Tinkham Peak is located just off the PCT. It offers trailhead access from at least two different starting points. The Mirror Lake Trail is by far the quickest route to the peak (6 miles roundtrip). A start in Olallie Meadows at the PCT trailhead is another option (approx. 8 miles roundtrip). Both provide easy going on good trail. Access to these trailheads is mentioned in the next section.

Getting There

Shortest approach from trailhead:
From Seattle, take I-90 E to exit 62 then take a right at the stop onto road 54. After 1 mile, take a right onto road 5480. It’s gravel from here on out and is typically in good shape. Follow this road for about 4.5 miles before reaching Lost Lake. Continue around the lake for another 2 miles and the Mirror Lake trailhead (3,600 feet) will be on the right.

Alternative starting point:
From Seattle, take I-90 East to Exit 54. Turn right at the stop. You immediately come to another stop, proceed straight onto Hyak Drive E. Continue past the ski area and then past the treatment plant to the gravel road. Road 9070 starts at this point. Follow it for 4.5 miles to the PCT trailhead in Olallie Meadows (elevation 3,800 ft) on the left-hand side of the road.
