Distance, round trip: 3 miles or 4 miles if you go to Queen's Laundry

Difficulty: moderate

Trailhead: 10 miles north of Old Faithful, turn left on Fountain Flat Drive. Park at the end of the road, cross the footbridge over the Firehole River to the trailhead.

Sentinel Meadows 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, 1.9 miles from the trailhead. 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.

*Very wet in spring and buggy in summer.
