Sentinel Meadows & Queen’s Laundry Trail

This trail starts deceptively simple — a flat stroll along the Firehole River that lulls you into thinking you're on a boardwalk nature walk. Then the path veers into open meadow, and suddenly you're wading through knee-high grass with steam rising from the earth ahead like some Victorian fever dream. The meadows are broad and treeless, so you'll feel every degree of sun or wind. The payoff is Queen's Laundry, where massive sinter mounds surround a hot spring that's been slowly encasing an 1881 bathhouse — the first government building ever constructed for public use in a national park. The ruins look like something nature is actively swallowing. This trail is perfect for history nerds and thermal feature enthusiasts who want Yellowstone's weird geology without fighting the Old Faithful parking lot.
