Trail Overview
Birth of a Lake Interpretive Trail is a short, scenic walk at Coldwater Lake that gives visitors an easy way to experience one of the most dramatic landscape changes caused by the 1980 eruption of Mount St. Helens. This accessible boardwalk trail follows the lakeshore and uses interpretive displays to explain how the eruption’s debris avalanche dammed Coldwater Creek and created an entirely new lake.

Trail Overview
Hummocks Trail is one of the best short hikes near Toutle for visitors who want a close-up look at the landscape reshaped by the 1980 eruption. This easy loop winds through rolling mounds, wetlands, young forest, and open viewpoints, with excellent views of Mount St. Helens and the North Fork Toutle River valley.
Trail Stats
About 2.5 miles round trip, 250 feet of elevation gain, and generally rated easy. The trailhead coordinates are 46.2869, -122.2717.
What to Expect
This family-friendly loop takes hikers through the strange, uneven “hummocks” left behind when the north flank of Mount St. Helens collapsed in 1980. Along the way, you’ll pass ponds, wetlands, recovering forest, and interpretive signs that help tell the story of how this once-barren blast zone became alive again. One of the best volcano views comes near the junction with the Boundary Trail, roughly a half mile from the trailhead.
Directions to the Trailhead
From Castle Rock, drive east on State Route 504 / Spirit Lake Highway for about 43 miles. Stay right at the fork signed for Johnston Ridge, continue about 2 more miles, and look for the signed Hummocks / Boundary Trailhead on the right.
Know Before You Go
The Forest Service currently lists no fee at the Hummocks Trailhead. Even with the ongoing SR 504 closure beyond milepost 45.2, Hummocks Trail remains open. The closure affects vehicle access farther up the highway, so Johnston Ridge Observatory and Loowit Viewpoint are not accessible by car, but the Hummocks Trail itself is still open for hiking.
Call to Action
If you’re looking for an easy Mount St. Helens-area hike with big scenery, fascinating geology, and a trail that works well for families, Hummocks Trail is a must-stop on your Toutle adventure.

Meta Lake is one of the easiest and most family-friendly walks in the Mount St. Helens area, offering a short paved interpretive path to a clear blue lake on the mountain’s east side. The trail itself is just 0.3 miles from the parking area, or about 0.6 miles roundtrip, with essentially no elevation gain, making it a great stop for travelers who want a quick scenic walk with a strong sense of the volcano’s recovery story. The Forest Service describes it as a place to discover how life survived in the blast zone, noting that the forest here endured the 1980 eruption under a blanket of snow.
What makes Meta Lake special is how much it reveals in such a short distance. The path leads from the parking area through a small stand of trees to the lakeshore, where a viewing platform looks out over water, recovering forest, and a landscape still shaped by eruption history. In midsummer, the Forest Service notes that visitors may even see swarms of tadpoles along the lakeshore. In spring, the end platform can flood, so conditions can change early in the season.
This is an ideal stop for families, road-trippers, and anyone building a scenic east-side Mount St. Helens itinerary. Because the trail is short and paved, it works well as a quick interpretive outing between viewpoints along Forest Road 99. To protect this fragile lakeshore habitat, visitors are asked to stay on the trail and viewing platform. The site is day use only, and the Forest Service prohibits off-trail travel, bicycles, stock use, camping, and swimming. Pets are allowed only on leash.
Trail details: Meta Lake Trail #210, near Mount St. Helens east side. Trailhead coordinates: 46.29597, -122.077136. Elevation is about 3,620 feet. A Digital Day Pass, Northwest Forest Pass, or Interagency Pass is accepted, and the day-use fee is $5 per vehicle.
Getting there: From Cougar, head east on Lewis River Road, which becomes Forest Road 90. Continue to Forest Road 25, then turn onto Forest Road 99 toward Windy Ridge. The Meta Lake Interpretive Site is about 9.4 miles up Forest Road 99.
Call to action: Add Meta Lake to your Visit Mt. St. Helens itinerary for an easy walk that pairs lake views, volcanic history, and a close-up look at how life returned after the eruption.
Current seasonal note: The Forest Service currently lists the Meta Lake Interpretive Site as temporarily closed and says it is inaccessible much of the year due to weather. Forest Road 99 is also listed as closed for winter, with the road gated at Wakepish Sno-Park as of January 30, 2026. More broadly, Forest Roads 25 and 99 are typically open from late June into November, so this is generally a summer-through-fall stop.
Ptarmigan Trail is the gateway to some of the most iconic terrain on Mount St. Helens. Beginning at Climbers Bivouac on the volcano’s south side, this trail climbs steadily through second-growth forest and small meadows before reaching timberline and the junction with the Loowit Trail. For many visitors, it is the first leg of the summer Monitor Ridge summit route, but it also works beautifully as a standalone hike for those who want a strong taste of the mountain without committing to the full climb.
What makes Ptarmigan Trail special is the transition it delivers in a relatively short distance. The route begins in cool forest, gradually opens into meadows, and then climbs toward broader volcanic views as you near the 4,800-foot level. The Forest Service says the trail reaches the Loowit junction in about 2 miles, while the broader Monitor Ridge route description notes Ptarmigan climbs about 1,100 feet in roughly 2 1/4 miles to timberline. That makes this a great option for hikers looking for a moderate uphill outing with a real sense of climbing into Mount St. Helens country.
Ptarmigan Trail is also an important dividing line for trip planning. Up to the Loowit Trail junction, this can be enjoyed as a day hike. Beyond 4,800 feet, travelers are entering the climbing zone for Monitor Ridge, where Mount St. Helens climbing permits are required year-round. Above timberline, the terrain becomes much steeper and more demanding, with lava flows, loose pumice, ash, and exposed upper mountain conditions.
Visitors should plan ahead for a more primitive trailhead experience. Climbers Bivouac has pit toilets, limited parking, primitive tent pads, and no potable water. A day-use pass is required for parking unless you are displaying a valid climbing permit for the date of your climb.
Trail details: Ptarmigan Trail #216A begins at Climbers Bivouac, near Cougar, Washington. Trailhead coordinates are 46.146695, -122.181703, and the trailhead elevation is about 3,736 feet. The Loowit Trail junction is reached in about 2 miles.
Getting there: From Cougar, take Lewis River Road / Forest Road 90 east for 6.4 miles, turn left onto Forest Road 83, continue about 3 miles, stay left onto Forest Road 81, then go about 1 mile to Forest Spur Road 830. Turn right and continue about 0.4 miles to Climbers Bivouac.
Call to action: Add Ptarmigan Trail to your Visit Mt. St. Helens itinerary for a rewarding uphill hike through forest and meadow to the edge of the volcano’s high country. It is one of the best ways to experience the south side of the mountain, whether you are heading for Loowit or simply enjoying the climb to timberline.
Current seasonal note: South-side vehicle access is still limited. The Forest Service says Forest Road 83 is closed and gated at Marble Mountain Sno-Park for winter conditions, and the Climbers Bivouac trailhead remains listed as temporarily closed, with the road snow-covered and impassable by most vehicles. If the summer trailhead is still closed, summit climbers are directed to use the Worm Flows winter route instead.
