Climbing information – Permits
Everyone must have a climbing permit to be above 4,800 feet elevation on Mount St. Helens.
The permit system helps to protect the volcano’s physical and biological features and processes, reduces crowding, and provides climbers with information on climbing conditions, Leave No Trace principles, and safety. The permit system has been in effect since 1987.
1. Mount St. Helens climbing permits are administered by Mount St. Helens Institute (MSHI) through an online vendor.
The MSHI online vendor is a secure website that accepts all major credit and debit cards. Climbers will be emailed a permit purchase confirmation receipt at the time of purchase.
2. The total permit fee of $22 includes a service charge which goes towards MSHI’s Mountain Stewards Volunteer Program to help maintain and protect the climbing routes. Climbing permits are not refundable. If climbing is suspended by the Forest Service, permit sales will also be suspended.
3. From April 1 to October 31 climbing permits are available online by advance purchase only.
Do not wait until the day of your climb to purchase your permit.
Unsold permits may be purchased online until 24-hours before the date of the climb.
4. Once you complete your permit purchase through the online vendor, all sales are final.
Refunds are not possible. You cannot change climbing dates once your purchase is complete. Please plan accordingly before completing your purchase.
