Boulder Peak (Suiattle River)

A steep hike to Boulder Lake, followed by easy scrambling to views from the western edge of the Glacier Peak Wilderness. It's 8 miles round trip and 3,300 feet of elevation gain.

Getting there

Drive SR-530 through Arlington and Darrington. Shortly after crossing the bridge over the Sauk River turn right onto the Suiattle River Road. At 8.1 miles turn left onto Forest Road 2660 (Tenas Creek Road) and follow it 7.2 miles to the parking area on right at 3,000 ft.

Approach & Ascent

From parking area hike the Boulder Lake Trail. It stays on north side of Tenas Creek until ~4,960 ft where it crosses Tenas Creek (where Tenas Creek mostly flows underground) and continues on to Boulder Lake. There are multiple routes to Boulder Peak. Perhaps the easiest is to head uphill before reaching Boulder Lake and following the easiest route suggested by the topographic map. An alternative is to skirt around Pear Lake and head toward the saddle southeast of Pear Lake and southwest of Peak 6220. Before reaching the saddle head, in a southerly direction toward Boulder Peak.
