Frequently asked questions

How long is the Loowit Trail loop around Mount St. Helens?

The Loowit Trail is about 47.07 kilometers, or roughly 29.2 miles, as a full loop around Mount St. Helens. It also packs in about 1,818 meters of elevation gain, so even though the mileage is moderate for a backpacking loop, the effort level is high and the route is considered extra difficult.

How many days does it take to hike the Loowit Trail?

Most hikers split the Loowit Trail into 2 to 3 days because the loop is about 47 kilometers with around 1,818 meters of climbing. Strong trail runners and very fit hikers sometimes do it in a single long day, but the rough volcanic terrain, repeated gully crossings, and limited water make it a serious undertaking.

Where do you start the Loowit Trail and where can you park for the Loowit Trail?

A common starting point for the Loowit Trail is Climbers Bivouac on the south side of Mount St. Helens, reached by Forest Road 830 off State Route 503 near Cougar. The Forest Service lists parking fees or a valid recreation pass at access points including Climbers Bivouac, Ape Canyon, and Windy Ridge, and it advises against overnight parking at June Lake because space is limited.

Do you need a permit to hike the Loowit Trail?

No backcountry permit is required just to hike the Loowit Trail itself. However, some trailheads used to access the loop require a parking fee or recreation pass, and a separate climbing permit is required only for travel above 4,800 feet on Mount St. Helens, which is a different rule from staying on the Loowit loop.

Is the Loowit Trail difficult and what makes the Loowit Trail so hard?

The Loowit Trail is widely regarded as a very strenuous loop because it combines about 47 kilometers of travel with roughly 1,818 meters of ascent on unstable volcanic ground. The route crosses pumice fields, lava-shaped terrain, and steep gullies, and some stream crossings must be forded, so it is best suited to experienced hikers and backpackers.

Are there water sources on the Loowit Trail?

Water can be a real challenge on the Loowit Trail. Forest Service and local monument guidance both note that some sections have scarce water, especially later in the season, and hikers should expect long dry stretches between reliable flows, particularly on the north and east sides of the mountain.

Are dogs allowed on the Loowit Trail?

Dog access around Mount St. Helens is restricted in parts of the monument, and pet rules can vary by zone and current management orders. Because the Loowit Trail circles sensitive volcanic terrain and passes through areas with special protections, dog access should be confirmed with current monument or Forest Service rules before planning a trip rather than assumed.
