Hike Description

Soda Peaks Lake, formerly known as Lost Lake, is in the southern portion of the Trapper Creek Wilderness in the Gifford Pinchot National Forest. It is about 15 miles north of the town of Carson. The Soda Peaks Lake Trail (#133) passes by the lake and has trailheads both east and west of the lake; see the hike description for the Soda Peaks Lake West Hike for the shorter option. This approach takes you over the sturdy new footbridge at Trapper Creek for an unrelenting ascent to the destination. There are a number of good campsites at the lake, which lies nestled in a glacial cirque below the summit of an old volcano that erupted about 360,000 years ago.

Note: The trailhead west of Government Mineral Springs (shown in the map below), making for a shorter hike of 7.0 miles round-trip to Soda Peaks Lake, has been decommissioned.

From the trailhead, enter Douglas-fir/hemlock woods with red-cedar, big-leaf maple, vine maple, a couple of western white pines, yew, sword fern, salal, Oregon grape, and red huckleberry. A few yards up is the Trapper Creek-Dry Creek Trail Junction. Continue on the Trapper Creek Trail #192. The tread ascends gradually and then keeps low along the side of Howe Ridge. This is old growth, with a few large hemlocks and Douglas-firs and many snags from an ancient fire. The woods are mossy, and a stunning glabrous green in wet weather. Enter the Trapper Creek Wilderness and then come to the Trapper Creek-Observation Trail Junction. Keep straight on Trail #192 and cross Lush Creek on a footbridge; then head up to traverse along the side of the ridge again. Some bigger Douglas-firs and a few silver firs appear. Cross a footbridge over a rushing creek and come to the Trapper Creek-Soda Peaks Lake Trail Junction.

Go left on this trail and descend below mossy, buttressed cedars, reaching an alder/big-leaf maple flat. A trail leads left to the Government Mineral Springs area and an unofficial trailhead; keep straight here to reach Trapper Creek. A sturdy new footbridge (2013) has been erected here. Pass under alders and then bear left to keep to the main trail. Passing some very large Douglas-firs and western hemlocks, you reach the Soda Peaks Lake-Soda Peaks Tie Trail Junction. The Soda Peaks Tie Trail used to connect to Government Mineral Springs, but it has now been officially abandoned.

Switchback up to the right under Douglas-fir, western hemlock, silver fir and yew. Keep switchbacking through woods of vanilla leaf, vine maple and cascara. There are openings created by blowdown where salal and cascara stand out. Reach the crest of the ridge, drop slightly, and then rise again. The trail skirts a knoll, from which there is a view of Mount Hood, and drops to a saddle, and then rises steeply again. Switchback at the ridge crest in hemlock woods and get views east to Observation Peak. There are some impressive Douglas-firs in this area also. Keep switchbacking up relentlessly. The trail rounds a rocky face, traverses through old growth and then passes across a vine maple/hazel scree slope. Head up again in old growth woods of Douglas-fir, western hemlock and silver fir. The trail levels and then drops, wending among some huge hemlocks. Then begin to traverse up again. On a clear day, you can take in views of Mount Rainier, Mount Saint Helens and Mount Adams along this section. The trail switchbacks and heads steeply up before reaching Soda Peaks Lake. Douglas-fir, western hemlock, Alaska yellow-cedar and silver fir surround the lake, which falls into deep shadow early in the afternoon. There’s a rushing outlet creek and a couple of decent campsites here. There are brook trout in the lake, so bring a rod if you want to fry one up for dinner.
