Six Mile Campground — North Cascades National Park

With no pets allowed, Six Mile Campground operates under National Park Service management within the Lake Chelan National Recreation Area portion of North Cascades National Park. The established campground sits in Washington's mountainous terrain, requiring advance planning for access and supplies. Campers should prepare for backcountry-style conditions despite the developed status, as services remain limited in this remote section of the park system. The pet restriction applies strictly across all sites. Visitors often stage from campgrounds near Stehekin before venturing deeper into the wilderness areas.
