Tamarack Flat Campground is a primitive, reservation-only campground in Yosemite National Park at 6,300 feet elevation near seasonal Tamarack Creek, offering 52 sites accessible only via a challenging 3-mile narrow, single-lane road (RVs/trailers not recommended).

The campground provides basic amenities including food storage lockers, fire rings, picnic tables, and vault toilets, but no potable water—creek water must be filtered, treated, or boiled before use.

A hiking trail departing from the campground provides access to Cascade Creek, El Capitan, and other points along Yosemite Valley's North Rim, with nearby giant sequoia groves within 5-10 miles.
