The Loowit Trail is consistently rated as strenuous or very difficult, recommended only for experienced hikers and backpackers. It involves constant navigation over loose volcanic ash, sand, scree, and large boulder fields. Expect frequent and challenging ascents and descents into deep gullies, some requiring rope assists. Route finding can be difficult in places, and most of the trail is exposed with little shade.
The terrain is diverse and challenging, reflecting the volcano's recent activity. You'll encounter extensive sections of volcanic ash and sand, boulder and lava fields requiring careful navigation and sometimes class two scrambling. Deep gullies, carved by lava flows, require steep climbs and descents, occasionally with Forest Service-installed ropes. Loose scree and pumice are common. The trail also crosses several washouts, notably at the South Fork of the Toutle River and Muddy Creek.
Yes, permits are required for hiking the Loowit Trail, as it is located within the Mount St. Helens National Volcanic Monument. Specific permit requirements can vary, so it's best to check the official Forest Service website for the most current information. You can find details on the USDA Forest Service website.
The best time to hike is typically from late July through September. Snow can linger on parts of the trail well into summer, and reliable water sources are scarce and seasonal, drying up quickly after snowmelt. Hiking earlier or later in the season increases the likelihood of encountering snow, colder temperatures, and potentially more challenging water crossings.
The Loowit Trail is a loop, so it can be accessed from several trailheads around Mount St. Helens. Popular starting points include the Ape Canyon Trailhead, Climbers Bivouac, and June Lake Trailhead. Parking availability varies by trailhead, and some may require a recreation pass. Always check current conditions and trailhead access before you go.
No, dogs are generally not allowed on the Loowit Trail or within the Mount St. Helens National Volcanic Monument's backcountry areas. This regulation helps protect the fragile volcanic landscape and wildlife. Always verify current regulations with the Forest Service before planning your trip.
The trail offers a dramatic 360-degree perspective of Mount St. Helens, including close-up views of its crater, the pumice plain, and the blast zone. Highlights include the On the foothills of Mount St. Helens, the Loowit Trail / Monitor Ridge junction, and the Campsite and South Fork Toutle River. You'll also experience vast volcanic landscapes, Loowit Falls, the Plains of Abraham, and Windy Pass, with views of other peaks like Mount Adams on clear days.
Reliable water sources are scarce and seasonal on the Loowit Trail, drying up quickly after snowmelt. Most of the trail is exposed, and water sources may also be silty from volcanic sediment. Hikers must plan carefully and carry sufficient water supplies, or be prepared to filter water from seasonal creeks.
Yes, while the Loowit Trail forms a complete loop around Mount St. Helens, the route also passes through sections of the Worm Flows Climbing Route, Toutle Trail, Monitor Ridge Climbing Route, and Castle Ridge Trail.
The Loowit Trail offers an unparalleled opportunity to hike around an active volcano with a very recent eruption history, allowing hikers to witness the immediate aftermath and ongoing regeneration of a volcanic blast zone. Many describe the experience as "otherworldly" due to the stark and unique terrain. It provides a visceral connection to the 1980 Mount St. Helens eruption and offers solitude and a significant challenge compared to other popular loop trails in the Pacific Northwest.
Given the trail's difficulty and exposure, essential gear includes sturdy hiking boots with excellent ankle support, navigation tools (GPS, map, compass), a water filter or purification tablets, and sufficient water carrying capacity. Pack layers for varying weather, sun protection (hat, sunscreen), a first-aid kit, and bear canister for food storage. Due to the challenging terrain and potential for route finding issues, a headlamp and emergency shelter are also highly recommended.
