Mount St. Helens Hikes
In 1980, when Mount St. Helens famously erupted, no one could have dreamed of the magical hiking destination it would become. Over 200 miles of trails allow access to a fascinating landscape marked by gorgeous summer wildflowers, young forests, new lakes, huge mounds of ash and rock and a growing volcanic crater rimmed by the state's newest glacier.
Mount St. Helens National Monument offers short hikes and excellent visitor centers for families, moderate hikes with grand views for day hikers and extremely difficult terrain — with true solitude — for backcountry enthusiasts. Each of the three access points is a gateway to a different experience and even long-time visitors will find something new in the hikes featured below.
Tips for hiking at Mount St. Helens
- Permits — Interagency or Northwest Forest Pass: Many trailheads in and around the Mount St. Helens National Volcanic Monument require a Northwest Forest Pass or Interagency pass.
- The Coldwater Science and Learning Center is open on Saturdays and Sundays from 10 a.m. to 4 p.m. in the winter. There is a parking fee of $5 per vehicle per day.
In summer (between mid-May and October), the center is open 7 days a week. in spring, summer and fall, there is no fee to visit. -
The Johnston Ridge Observatory/Visitor Center is closed through 2026 due to a landslide on SR 504.
Options for entry to the Johnston Ridge Visitor Center:
- Interagency Annual and Senior pass
- Northwest Forest Pass will grant access to one person
- Day pass is $8 per person for those 16 and older, and free for kids. - Be prepared for the elements! With little tree-cover, hikers are exposed to the sun, the rain and especially the wind. Bring a hat, sunscreen, sunglasses and layers to adjust to the changing conditions.
- Carry lots of water. Water is scarce along many of the trails, so it is important to bring plenty of it with you.
- Leave your pups at home. Due to the sensitive ecosystem, dogs are not allowed in many areas of the park.
From the west
The west side of the Mount St. Helens National Monument was transformed by the 1980 eruption. Old growth forest gave way in an instant to the explosion and subsequent lahar and mudflow. A new lake was formed. Today, this area is one of the most popular entrances to the Monument, and it's easy to see why. Almost every mile of trail offers excellent views into the mouth of the crater and profuse wildflowers line the pumice plains and ridges.
Hummocks Trail

Thirty years ago this was an old growth forest. Not anymore! While life has certainly returned to this valley, the landscape is now defined by towering mounds of ash, rock and mud.
This is a great trail to gain an appreciation of the devastating effects of the eruption of Mount St. Helens and to marvel at the vitality of nature's return. The loop trail takes you by small ponds, the North Fork Toutle River and hummock mounds up to 500 feet high.

This is a classic, leaving from the Johnston Ridge Observatory. The hillsides are alive with wildflowers at mid-summer, and the view from the end of Harry's Ridge has you looking straight into the mouth of the crater. You have a direct view of Loowit Falls and an emerging glacier. Plus, incredible views of Spirit Lake, Mount Adams and even Mount Hood on a clear day.

Believe it or not, Coldwater Lake didn't even exist before the 1980 eruption. The ancient forest that once towered here was blown away and dammed up Coldwater Creek. Now, a large and beautiful lake tempts visitors with fabulous hiking on both sides. This is also a great trail from which to view wildflowers and wildlife, especially elk.

From the east
Trails accessed from the northeast offer a variety of habitat. Some areas were beyond reach of the blast and today enjoy the cool shade of ancient forests. Closer to Windy Ridge the topography changes considerably from ghostly Spirit Lake with silver logs still floating in its waters, to old trees all blown down in the same direction, and lots and lots of wind. This is the edge of the blast zone.
Meta Lake
Location: Randle Area
Mileage: 1.3 miles, roundtrip
Elevation Gain: 500 feet

The trail to Meta Lake is short, sweet and paved - offering a barrier-free hike that is accessible for people in wheelchairs. Despite being in the blast zone, this area is defined by a young forest. These trees survived the eruption by being under a thick blanket of snow. The quiet lake is a fun destination for kids, especially in mid-summer when they can look for tadpoles and trout in its clear waters.

This area was filled with 600 feet of mud from the landslide triggered by the Mount St. Helens eruption. Today, birds and wildlife abound on the plains. The trail descends directly into the blast zone, and continues by the crater. Rock, ash, and mud dominate the terrain for two miles until reaching the Pumice Plains by Spirit Lake. Alongside the lake, take in views of the volcano and the region impacted by the eruption.

From the north
Visiting Mount St. Helens from the north is a more remote experience. Many of these trails start outside the blast zone, and hikers have to work their way in, appreciating the stark change in scenery that much more. Views of the mountain in the distance, and longer approaches make for a rewarding exploration of a different side to this iconic volcano.
Goat Mountain and Deadman's Lake

From the south
The south side of Mount St. Helens was left almost untouched by the events of May 18, 1980, but has been sculpted by other lava flows over the centuries. Hikers here will get a completely different experience with caves, canyons, forests and access to the crater rim.
June Lake

Lava Canyon
The suspension bridge on the Lava Canyon trail is currently closed due to cable damage, rendering the 1.4-mile upper loop of the trail unreachable.
Location: Outside the town of Cougar
Mileage: 5 miles roundtrip

If you’re a thrill seeker, look no further than Lava Canyon. Starting on a paved interpretive trail, this route crosses a springy suspension bridge before plunging into the Lava Canyon Gorge. At the bottom of the gorge (a descent which includes climbing down a 30-foot ladder), the trail winds along a steep and narrow section, passing “The Ship” spur trail, which leads to scenic views of nearby waterfalls. On top of being an exhilarating trip, the trail offers a unique perspective on the power of volcanic eruptions: The gorge was filled by sediment until it was scoured clean by lahar flows during the 1980 eruption.

Make no mistake. Climbing to the summit of Mount St. Helens is exhausting business. But the happy news for non-climbers is that you can reach the top without technical skills, making this singular experience within reach for hearty hikers willing to endure several miles of boulder fields and ash climbing. It's amazing and awe-inspiring to stand on the rim of this not-so-quiet volcano and watch geology in the making.
Permits are required to climb to the summit and are available online from the Mount St. Helens Institute after March 1, released in one-month increments on the first day of the previous month. Plan early if you wish to climb the volcano during the peak season or on weekends.

This is the go-to route to the summit when Mount St. Helens is covered in snow. It is direct, but that doesn't mean it's easy. Long miles of snow travel can be grueling, but luckily this route is not too technical. It is considered a good intro to mountaineering, and the views at the top are stunning.

The Loowit trail circumnavigates Mount St. Helens in around 32 miles. To be sure, this is a challenging route becauase the trail climbs in and out of the many gullies that form the flanks of this mountain. Conditions are shifting in these environments, so some route finding is necessary. No other trail will give you such a comprehensive look at this iconic mountain.
