Thunder Basin Stock Campground

Thunder Basin Stock Campground is a designated backcountry stock camp located along the Thunder Creek Trail in North Cascades National Park, situated at the base of a hanging glacial valley approximately 15 miles from the trailhead at Colonial Creek Campground.

The camp features a river ford crossing and serves as a key waypoint for multi-day backpacking trips, with a separate hiker camp located 1. 3 miles further uphill in subalpine meadows.

A backcountry permit is required for overnight stays, and the camp is best accessed via the Thunder Creek Trail from State Route 20 near Diablo Lake.
