Mystic Falls is a 70-foot waterfall on the Little Firehole River in Yellowstone National Park, reached via a scenic 2.4-mile round-trip hike from Biscuit Basin in the Old Faithful area. The trail passes through thermal features and lodgepole forest, providing a popular morning or afternoon waterfall walk.
Important access note: Biscuit Basin’s main parking lot and boardwalk have been closed since July 2024 due to a hydrothermal explosion. However, trail access to Mystic Falls remains available via an alternate route: park in roadside pullouts approximately 0.25 miles south of the closed Biscuit Basin area and walk 0.5 miles north to reach the trailhead. This adds only 1 mile round-trip to the standard distance. Visitors should verify current access status with the NPS before visiting to confirm the alternate parking area is open.
Dogs are not permitted on any NPS trails, including this one. Yellowstone’s $35 per vehicle, 7-day entrance fee applies. The trail itself carries no closure alert as of September 2026, though visitors should contact the park or check the official website for the most current information on parking and access conditions.
Summer through fall; no official seasonal closure is posted for the falls trail itself.
Biscuit Basin parking is currently closed. Alternate parking is available in roadside pullouts about 0.25 mi south of Biscuit Basin.
Dogs are not permitted. Be aware that Biscuit Basin parking lot was closed due to a 2024 hydrothermal explosion.
Located in the Old Faithful area; can be combined with other thermal features and geysers.

NPS Mystic Falls Trail page (checked 2026-09-04): 70 ft waterfall on the Little Firehole River, 2.4-mi round trip from Biscuit Basin. Dogs not permitted per the page's explicit note. CLOSURE CHECK: Biscuit Basin itself (parking lot/boardwalk) has been closed since a July 23, 2024 hydrothermal explosion. The current NPS Mystic Falls Trail page shows no closure alert and describes an alternate access — parking in pullouts about 0.25 mi south of Biscuit Basin and walking 0.5 mi north — that bypasses the closed area. Included on that basis; visitors should verify current status before visiting.
