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.
The campground is located on the southern side of State Route 20, with some campsites along the lakefront of Diablo Lake. The entire facility offers drinking water, flush toilets, garbage removal and some paved parking spaces, but most sites have uneven gravel parking. Each campsite offers a picnic table and campfire ring.
