About
Overview
Colonial Creek South Campground in North Cascades National Park is a remote, yet bustling campground nestled in old growth forest. Located on the south side of State Route 20 near mile marker 130, there are 94 campsites that are surrounded by forest and located on Diablo Lake.
Recreation
Visitors can access several trails from within the facility, such as Thunder Knob Trail and Thunder Creek Trail. Colonial Creek South Campground is also close to several trails along State Route 20. Visitors can also go boating, fishing, and swimming (although the water is a chilly 43 degrees) on Diablo Lake. Bears do inhabit the area, so care should be taken when hiking, picnicking, or camping.
