Mist Trail Closure

The Lower Mist Trail- from the John Muir Trail (JMT) junction (just uphill from the Vernal Fall Footbridge) to the top of Vernal Fall – will be closed Mondays through Fridays from September 8 to November 21 between the hours of 7am and 4pm. The trail will remain open on weekends.


The trail is expected to be open overnight, however there may be certain days when trail crew is not able to make it safe to open overnight. In that case, the gates will remain closed and signs will be posted at the two closure gates that the trail is closed.


Hikers and backpackers headed to Half Dome, Cloud’s Rest, and points beyond from the trailhead at Happy Isles may hike uphill on the Mist Trail as long as they reach the Mist Trail/JMT junction by 7 am, Mon–Fri. Otherwise, they must hike up the JMT (approx. 1 mile longer).


Mon–Fri, hikers and backpackers traveling downhill/returning to the trailhead are encouraged to use the JMT to descend at all times since it will not be possible to change the sign at the trail junction at the Nevada Fall restroom anytime the Mist Trail needs to remain closed overnight.


There is a $280 fine for entering a closed construction zone.  (J. Marschall)



Big Oak Flat Road Work

When smoke conditions improve, Mather Roads will resume working on Big Oak Flat Road 7AM – 3:30PM, Monday – Thursday, starting at the park boundary and working toward the east. Use caution and look out for employees and equipment on the road. Expect traffic delays.  (B. Brantley)



Valley Forestry

Valley Forestry will be removing hazard trees along Glacier Point road between Summit Meadow and Glacier Point Monday – Thursday until further notice.  Anticipate traffic delays.  (B. See)



Bridalveil Fall

The Bridalveil Fall parking lot and trails are closed to visitation to allow for ongoing rehabilitation work. NPS crews are currently constructing a new accessible trail and making other trail and site repairs. Contractor work consisting of utility upgrades and parking lot and bus platform improvements will begin later this summer and will continue through May 2021.  (P. Johnson)



PG&E Construction At Cascades Substation

Continuing through October, PG&E and their contractor are constructing a spill prevention wall around the electrical transformers at Cascades Substation (about 3.25 miles from Arch Rock).  In the event of a transformer failure, the wall will prevent oil from spilling into the Merced River.  Expect traffic control measures and periodic traffic delays at the substation to be in effect as the contractor is mobilizing and staging materials.  (M.
