Experience the dramatic landscape reshaped by the 1980 eruption, where lava domes, blast zones, and regrowing forests tell a powerful story of destruction and renewal. Explore scenic viewpoints, lava trails, and visitor centers while witnessing one of the most active and studied volcanoes in the world.
From US-12 (White Pass Scenic Byway) travel east to Randle, Washington.
In Randle, turn south onto State Route 131. After about 2 miles, SR-131 ends at a T-intersection. Turn left onto Forest Road 25 (FR-25). Follow FR-25 south for approximately 25 miles.
Turn right onto Forest Road 99 (FR-99). This is the signed turn for Windy Ridge Viewpoint / Mount St. Helens National Volcanic Monument.
Continue about 9 miles to the Windy Ridge parking area and viewpoint overlooking Spirit Lake and the blast zone.
FR-25 and FR-99 typically open late June or July (not early spring) due to deep snowpack
Roads usually close again in October or after the first major snowfall
These are narrow mountain roads with limited services — fuel up in Randle
Expect steep grades and sharp curves
Cell service is very limited after leaving Randle. Download maps before heading out.
The Johnston Ridge side approaches Mount St. Helens from the west side of the volcano and is the most direct route to the crater viewpoint.
From I-5, take Exit 49 (Castle Rock / Mount St. Helens Visitor Center). Head east on Spirit Lake Highway (SR-504).
Follow SR-504 for 52 miles (no turns required).
The road ends at Johnston Ridge Observatory, overlooking the crater and pumice plain.
SR-504 is plowed in winter, but the final section to Johnston Ridge typically opens mid-May to late May (sometimes June in heavy snow years).
In winter or early spring, access usually stops at Coldwater Lake.
Fuel, food, and services are only available in Castle Rock.
Expect winding mountain driving the final 20 miles
Cell service becomes limited past the Hoffstadt Bluffs area
Clear mornings offer the best volcano visibility before clouds build
This route accesses the south side climbing and hiking area of Mount St. Helens and is the starting point for the summer summit climb and many popular trails.
From I-5, take Exit 21 and drive east on State Route 503 toward Cougar.
At Cougar, stay on SR-503 (Lewis River Road) for about 7 miles.
Turn left onto Forest Road 90 (FR-90) toward Marble Mountain Sno-Park.
Follow FR-90 approximately 6 miles to Marble Mountain Sno-Park (winter access) or continue another 2 miles to Climber’s Bivouac trailhead (summer access).
Marble Mountain Sno-Park is open year-round (winter permit required)
Climber’s Bivouac road typically opens late June–July and closes after snowfall (usually October)
This is the primary summer route for climbing permits
No fuel past Woodland — fill up early and cell service fades quickly past Cougar
Weather changes rapidly on this side of the mountain
A climbing permit is required above treeline
Before 1980, Mount St. Helens was blanketed in dense forests, alpine meadows, rivers, and lakes. Old-growth trees covered much of the mountain, and wildlife, including elk, deer, birds, amphibians, and small mammals, thrived across a wide range of elevations. Before the 1980 eruption, Mount St. Helens was widely regarded as one of the most symmetrical and visually striking volcanic cones in the Cascade Range, often described as a nearly perfect cone.
On May 18, 1980, a massive volcanic eruption at Mount St. Helens dramatically reshaped the surrounding landscape. A powerful landslide and lateral blast flattened vast forests, while ash and debris swept through valleys and river systems. The eruption created entirely new landforms, including lava domes, newly formed lakes, and exposed ridges of volcanic rock. In just minutes, ecosystems that had developed over centuries were completely transformed, marking one of the most significant volcanic events in modern U.S. history.
In the years following the eruption, Mount St. Helens became a living laboratory for ecological recovery. Plants began returning sooner than expected, with wildflowers, grasses, and shrubs taking root in volcanic soils. Over time, forests slowly regenerated, wetlands formed, and streams stabilized, creating new habitats.
As plant life returned, wildlife followed. Today, visitors may spot elk grazing in recovering meadows, amphibians near wetlands, birds nesting along cliffs and forests, and small mammals adapting to the ever-changing terrain. Each season brings visible signs of renewal.
Mount St. Helens continues to evolve, offering a rare opportunity to witness nature’s resilience and the ongoing process of recovery firsthand.
For thousands of years, the Mount St. Helens area has been deeply significant to Indigenous peoples, including the Cowlitz, Yakama, and other tribes, who lived, traveled, and gathered throughout the region. The mountain was an important cultural and spiritual landmark long before modern settlement.
In the late 19th and early 20th centuries, the surrounding forests supported logging, recreation, and growing communities. The May 18, 1980 eruption of Mount St. Helens forever altered both the landscape and the cultural identity of the region, drawing global attention and reshaping how people understand volcanic forces. Today, the area serves as a place of learning, reflection, and connection, honoring both its deep cultural roots and its powerful natural history.
