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 accessible from May until October.
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.
