Thunder Basin Hiker Campground is a backcountry campsite located in a subalpine meadow setting along the Thunder Creek Trail in North Cascades National Park, approximately 15 miles from the trailhead at Colonial Creek Campground.

The camp accommodates hikers and stock parties, with a designated stock camp located 1 mile downslope; a backcountry permit is required for overnight stays.

This small camp is situated at high elevation with views of Park Creek Pass and requires fording Thunder Creek to access—avoid crossing during high water periods.
