You’ll find Igloo Creek, near Igloo Mountain, at mile 34. It’s a tiny, isolated campsite one-third of the way into the park. The campground is open from May 20 to September 12. There are seven tent-only sites and vault toilets; there is no potable water. Fees are $15/night. Access is only via the park shuttle bus. Note: Advanced reservations are not possible for Igloo Creek. Sites are first-come, first-served. Photo via Michelle Houlihan, shutterstock
