Thing to Do

Sentinel Meadows & Queen’s Laundry Trail

Hydrothermal features steam in the middle of a wide-open field.

The trail follows the Firehole River a short distance, then veers toward the meadows. Look for the large sinter mounds of hot springs and the remains of the old, incomplete bathhouse at Queen’s Laundry. Begun in 1881, construction was abandoned as park administrations and priorities changed. Minerals from the hot springs preserved the structure, which was the first building constructed by the government for public use in any national park. Queen’s Laundry is a National Historic Site.

Safety notes: Hiking off-trail in the hydrothermal areas is not permitted.

Trailheads: Park at the end of Fountain Flats Drive and cross the bridge over the Firehole River.

This is a 3.8-mile (6.1-kilometer) there-and-back trail that begins and ends at the same trailhead.
