Trail #225 Smith Creek

Area Status: Unreachable

The south end of the Smith Creek Trail has suffered significant damage. Hikers using the trail from the Lower Smith Creek trailhead should be aware of obstacles including downed trees, eroded cliff areas and loose trail tread.


The Smith Creek Trail offers a chance to observe the immense impact of the 1980 eruption. This section is part of the popular Ape Canyon /Smith Creek Mountain Bike Loop.

The trail quickly drops from the trailhead at Forest Road 99 into the Smith Creek valley. Two waterfalls are located near the foot of the steep-descent. Following the valley bottom, the trail crosses Ape Canyon Creek and then Muddy River. Here the trail intersects Lava Canyon Trail #184. Continue downstream for 1 mile to the Lower Smith Creek Trailhead at Forest Road 8322.

Special Conditions: Loose pumice surface, especially at the northern end of the trail.
