About this permit
A climbing permit is required year round to climb Mount St. Helens, but the quota only applies from April 1 to October 31. In that window USFS caps the mountain at 350 climbers per day from April 1 to May 14, and 110 climbers per day from May 15 onward. Group size is limited to 12 individuals.
Permits are released in one-month blocks on the first day of the preceding month at 7:00 a.m. Pacific: April permits go on sale March 1. The recreation fee is $20 per climber per day, raised from a lower figure for the 2024 season, plus a non-refundable $6 reservation fee per transaction. A permit holder can hold a maximum of five permits at a time and is restricted to one permit per day.
From December 1 to March 31 there is no cap on the number of climbers, and permits are free and self-issued at the trailheads. That is the same mountain, the same closure area and the same rules, just no reservation and no fee, in exchange for full winter conditions.
The route
USFS describes the climb as strenuous but non-technical, suitable for people in good physical condition who are comfortable scrambling on steep rugged terrain. There are two trailheads and they split by season: Climber's Bivouac is the summer route, and Marble Mountain Sno-Park is the winter route.
The permit is valid from 12:01 a.m. to 11:59 p.m. on the date printed on it, and it does not authorize entry into the crater. The crater is closed to all entry. Within that constraint, individuals may choose their preferred route to the summit.
Overnight use inside the closure area requires two permits for two consecutive days. That is the only way to legally sleep up there.
Why it matters
Before May 18, 1980, Mount St. Helens stood 9,677 feet and was the fifth-highest peak in Washington, the conical snow-covered mountain people called the Mount Fuji of America. The eruption removed an estimated 3.4 billion cubic yards of the cone, about 1,300 feet of height, and left a horseshoe-shaped crater open to the north. The southwestern rim, at 8,365 feet, is what you climb to now. USFS calls it the most active volcano in the Cascade Range, present tense.
The feeling
The route starts in forest, breaks out into boulder fields, and then turns into ash and pumice that gives back half of every step. And then it stops, abruptly, at an edge, with the crater and the dome below you and Rainier, Adams and Hood arranged around the horizon.
