The Mystic Falls Trail is a 3.5-mile-long loop trail that follows the boardwalk and runs along the Little Firehole River before reaching the 70-foot Mystic Falls.

The trail will take you by lovely Black Opal Pool, by a magnificent blue pool called Sapphire Pool, past Jewel Geyser and many other hot springs and geysers, and through a slowly regenerating area of burnt forest until you reach a spectacular spot overlooking the Upper Geyser Basin.

It is the best and least crowded place to watch Old Faithful, with good binoculars.

The first part of the trail is easy and fun for the kids, so bring them along. After that there is a short but rough climb to the Madison Plateau.

As you go down from the overlook, be careful of small rocks that slide down the steep incline. Look for cute yellow-bellied marmots along the trail. The trailhead can be found at the Biscuit Basin parking area.
