Sentinel Meadows Trail is a 3.2 mile moderately trafficked out and back trail located near Yellowstone National Park, Wyoming that features hot springs and is good for all skill levels. The trail offers a number of activity options and is best used from May until October.
We made this into a loop hike with Imperial Meadows & Fountain Flat Drive. If I figured it out right, that makes 7.8 miles. Parking at the trailhead looks generous, but in the afternoon, might be kind of tight.
This is a good hike for kids. The trail is flat, with no elevation gain. There were bison around, but in the distance. The view of Queen's Laundry is tough with all the steam. If you want, you can take a 0.1 mile stroll to get a closer look.
This is a nice afternoon hike, after the craziness of Old Faithful. We saw maybe 5 people on the trail, not including 2 bikes on Fountain Flat Drive. We also saw a coyote while on the trail.
You might loose the trail coming in from the north side of the loop, but you will see the big white mounds of the Queens Laundry hot springs to guide you. The markers on the south side where the trees start are very obvious where the trail picks up. No one else was on the trail, it was really easy with little or no elevation gain, just great views and cool thermal features away from the board walk.
