Active Pursuits in Mount St. Helens National Volcanic Monument

If you're an experienced hiker in good physical condition, the climb to the summit of Mount St. Helens is a must. From the trailhead on the south side of the mountain, the hike takes 8 to 10 hours and can require an ice ax. Climbing permits, which cost $22 between April and October and are free other months, are required and are only available online (www.fs.fed.us/gpnf/mshnvm). Because the climb is very popular, you'll need to make a reservation. Reservations are taken beginning on February 1, and summer weekends book up fast. Between November 1 and March 31, no reservation is necessary -- but expect lots of snow. Due to volcanic activity in recent years, the rim is sometimes closed to hikers, so check the current status before planning this climb.
