Mystic Falls Loop is an easy day hike to a 70-foot Yellowstone waterfall.
Mystic Falls is located in the Biscuit Basin area of Yellowstone National Park. Biscuit Basin’s parking lot is approximately 2 miles north of Old Faithful along Grand Loop Road.
Start your hike along the Biscuit Basin boardwalk. The boardwalk provides access to several thermal features including the popular Sapphire Pool. The actual trail for Mystic Falls begins near Avoca Spring at the west end of the boardwalk. Here the trail turns to dirt and enters a pine forest. You’ll quickly emerge into a beautiful canyon and follow the Little Firehole River until you reach the falls (approximately 0.7 miles from the boardwalk).
Once you reach the falls you can either return the way you came (2 mile out and back) or continue and make a loop hike (3 mile loop). If you’re going to loop, continue the incline above the waterfall until you reach the junction for Fairy Creek Trail. Turn right and the junction. Here you’ll descend to Biscuit Basin Overlook. This is a nice destination to rest, eat a snack and take in the view. Continue on the trail until you meet back up with the boardwalk at Biscuit Basin.
