Mount St. Helens/Worm Flows


Intermediate Snowshoe - Mount St. Helens/Worm Flows

Annual trek up my favorite volcano before the permit season begins!

  • Very Strenuous
  • Challenging
  • Mileage: 12.0 mi
  • Elevation Gain: 5,700 ft

Marble Mountain Sno-Park @5AM. See trip plan. Recommend car camping the night before.


This is at the upper end of difficulty for intermediate snowshoeing trips. As such, only graduates of either intermediate snowshoeing, scrambling or climbing will be considered.

We will target a pace that gets us up in 5 hours and down in 2.5 (through copious glissading, I hope). Priority is given to folks who were signed-up for my previously canceled attempts, but if you are not one of those people, you can still request permission. Crampons (and obviously snowshoes) will be required.
