Many backpackers prefer to spend the night for longer hikes, especially when they have heavier gear with them like a bear can. Backcountry camping in North Cascades is allowed, but you must obtain a backcountry permit for overnight stays. These are available on a first-come, first-served basis and can be obtained at visitor centers. Otherwise, camping is only allowed in established campgrounds like Colonial Creek, Newhalem, and Goodell Creek.
