This spring and early summer, trail crews are finishing a new trail and overlook to replace the many existing social trails on the hills south of Grand Prismatic Spring. The new trail and overlook is expected to open later this summer (no earlier than July 1, 2017), and will allow people to safely enjoy this popular destination that provides spectacular views of Grand Prismatic Spring and Excelsior Geyser.

To facilitate this work, the following areas are closed to the public:

  • The hills immediately south of Grand Prismatic Spring
  • The Fairy Falls Trailhead and parking lot (located one mile south of Midway Geyser Basin)
  • The Fountain Freight Road between the parking lot and the Fairy Falls Trail junction
  • In addition, the area east of the Grand Loop Road around Midway Bluff is closed permanently due to resource damage from visitor use. See map below for more details.

These closures will not affect access to the boardwalks around the Midway Geyser Basin. Hikers can access Fairy Falls using the Fountain Freight Road Trailhead located north of Midway Geyser Basin. Be prepared for a much longer hike: 8.8 miles round-trip rather than 5 miles round-trip.

Cyclists can ride from the Fountain Freight Road Trailhead as far as the Fairy Falls Trail Junction (6 miles round-trip). Bicycles are not allowed on the Fairy Falls Trail: you must complete this section on foot (2.4 miles round trip).
