Views of a rushing ribbon of pools and waterfalls await visitors on the Lava Canyon Trail on the south side of Mount St. Helens.
Three sections of the trail, one section which is accessible, provide opportunities for all.
Due to closure of the Lava Canyon Suspension Bridge, the 1.4-mile upper loop is not possible. The first small bridge remains open for crossing the river.
Visitors may still walk down both sides of the river to the suspension bridge, but cannot cross it.
Although it may be tempting to leave the trail and explore, going off-trail is dangerous and fatalities have occurred. The U.S. Forest Service asks visitors to stay on the trail at all times.
The first 1/3 mile is paved and accessible. Stroll down some switchbacks and past lovely views of the Muddy River. Stop to read interpretive signs explaining the canyon’s geological past.
After the first 1/3 mile, the pavement ends. To the right, cross a steel bridge, gaze down on the rushing Muddy River and explore the river’s east side or continue straight on the main trail for another 0.4 miles to the suspension bridge.
Normally, you can cross the suspension bridge to make a 1.4-mile loop, but due to the bridge’s closure, this is currently not possible.
On the main trail, beyond the suspension bridge, the terrain becomes more difficult, descending steeply into the canyon. This section is not recommended for people uncomfortable with heights.
The trail crosses an exposed cliff face followed by a water crossing with a cable grab-line. A 30-foot metal ladder descends a vertical cliff, providing access to the canyon's deepest recesses and roaring waterfalls. The canyon broadens out as it approaches the Smith Creek Valley. The trail ends at Smith Creek Trail #225.
To get there from Woodland, take state Route 503/Forest Road 90 east to the well-signed junction with Forest Road 83.
Take a left on Forest Road 83 and follow for 12 miles to Lava Canyon Trailhead/Interpretive Site at the end of the road.
