Mystic Falls Trail

Mystic Falls Trail is a 2.4-mile (3.8 km) out-and-back from the west end of the Biscuit Basin boardwalk to a 70-foot waterfall on the Little Firehole River. The creekside path through mixed conifer forest makes the approach part of the visit, not just a walk to a viewpoint. Plan about two to four hours with stops; turning around at the falls keeps it shorter, while the high overlook loop adds a real climb. This entry maps the falls outing and return along the same corridor. The longer Summit Lake route continues beyond the trail junction, so don't follow it unless that backcountry trip is your plan.

From the Biscuit Basin parking area, walk about 0.3 mile around the boardwalk to the Mystic Falls Trailhead at its far side. The footpath then follows a creek through mixed conifers toward the Little Firehole. Near the falls the river-side tread narrows above steep banks, so give yourself room to place each step. The best view of the cascade is from the trail's switchbacks; stay on the established tread instead of scrambling down the loose bank for a closer angle.

At Mystic Falls, the Little Firehole River drops about 70 feet from the Madison Plateau. The water steps through a rocky canyon, with the creek continuing below it, so the view includes both the drop and the channel rather than a single plunge. Pause on the trail-side viewpoint and look up and downstream before turning back. A steep descent to the base is not part of the ordinary route and is a poor trade for a closer photo.

From the falls, you can climb switchbacks to an overlook above Upper Geyser Basin, then loop back to the main trail. That extension adds about 1.5 miles and roughly 500 feet of climbing. It changes a moderate waterfall walk into a noticeably steeper outing, with narrow, eroded sections reported around the descent. Choose it for the broader basin view and the extra effort, not because you need it to see Mystic Falls. From the ridge, the Old Faithful area is visible; a few hikers have caught an eruption from there, but it depends on timing and visibility.

The trail is moderately strenuous even without the high loop, and the narrow riverbank section is the part that asks for the most care. Keep to maintained paths and boardwalks around hydrothermal ground. Pets are not allowed. No separate hike fee or reservation is listed, though normal park entry applies. No restrooms or potable water were found at the trailhead; fill up and use facilities in the Old Faithful area before you start. The trailhead itself is at the far side of the Biscuit Basin boardwalk, about 0.3 mile from parking.
