Frequently asked questions

How long is the Mount St Helens Area Loops hike and how many days does it usually take?

Mount St Helens Area Loops covers 73.93 km, or about 46 miles, with 2,542 meters of climbing. At that length and elevation gain, it fits best as a multi-day backpacking route, and many strong hikers would split it into roughly 3 to 5 days depending on camp locations, weather, and pace across the volcanic terrain.

How difficult is the Mount St Helens Area Loops hike in Skamania County?

Mount St Helens Area Loops is rated Extra Difficult, which matches its nearly 74 km distance and 2,542 m of ascent. The challenge comes not just from the mileage, but from long exposed sections, steep climbing, and the loose volcanic surfaces common around Mount St. Helens, especially on routes linked to the Loowit Trail and nearby junctions.

Where do hikers usually start the Mount St Helens Area Loops hike?

Common access is from the Mount St. Helens National Volcanic Monument road network in Skamania County, with State Route 504 serving the west side and trail access also used from the south side near Cougar. Trailheads commonly associated with longer loop travel around the volcano include Ape Canyon and June Lake, while the monument itself is managed within Gifford Pinchot National Forest.

Is parking easy for the Mount St Helens Area Loops hike?

Parking depends on which trailhead is used, but access is more limited than at a typical front-country trail. June Lake is day-use only, so it is not a good choice for leaving a vehicle on a multi-day trip, and west-side access on SR 504 has also been affected by the long-running Johnston Ridge area closure after the 2023 South Coldwater Slide, with reconstruction work underway in 2026.

Do you need a permit for the Mount St Helens Area Loops hike?

A summit permit is required only for climbing above 4,800 feet on Mount St. Helens itself, not for ordinary hiking on lower monument trails. Overnight travel can require backcountry permits in specific managed zones, especially in the Mount Margaret Backcountry between May 1 and November 30, so permit needs depend on the exact loop and camps used.

Can you bring dogs on the Mount St Helens Area Loops hike?

Dog access is not universal around Mount St. Helens, and rules can vary by trail segment and management zone, so it should not be assumed that the full Mount St Helens Area Loops route is dog-friendly. Because this route links multiple monument trails and backcountry areas, checking the current regulations for the exact trailheads and segments planned is important before setting out.

What is the best time of year to hike the Mount St Helens Area Loops?

The main hiking season is typically summer into early fall, when higher roads and snowbound trail sections are more likely to be open. On the east side, the road to Windy Ridge is commonly closed until late June or early July as snow melts, so July through September is usually the most reliable window for a long loop in the Mount St. Helens area.

Are there water and camping challenges on the Mount St Helens Area Loops hike?

Yes. Longer loops around Mount St. Helens often cross dry volcanic slopes where water can be scarce, especially on exposed sections of the Loowit Trail. Camping is also regulated in some areas, and there are no-camping stretches near sensitive zones, so daily mileage often has to be planned around both legal camps and dependable water rather than distance alone.
