Heart Lake and the Snake River Trails is a 48.8 mile lightly trafficked out and back trail located near Yellowstone National Park, WY that features a lake and is rated as difficult. The trail offers a number of activity options and is accessible from July until September.
Very exposed hike with some elevation- make sure to bring water or a water filter.
Beautiful hike. Hiked from Heart Lake down to South Entrance. The section from HL to Sheridan Lake is amongst the most beautiful parts of the park. Lots of bear sign, saw one grizzly on South Boundary trail n ar the scree field. Don't pass up this hike even though the guide book says it isn't that great.
Staying at campsite #6 is AMAZING!
