Current Status of Parks & Trails 7/13/26
All parks not listed below are currently open for normal use.
The Northern Section of the Oat Hill Mine Trail (Between the Palisades Trail junction at Holm’s Place and the Aetna Springs Trailhead) is closed 8/8/26-9/20/26.
The northern section of the Oat Hill Mine Trail is closed during this period for two reasons:
- High Risk of Wildfire: There is almost no cell reception, and this segment of trail is extremely remote. Evacuation and rescue is difficult on this section of trail.
- Hunting Season: Deer hunting season is open during this time period and this trail passes through private properties that allow hunting.
Berryessa Peak Trail – There is a landslide approximately 4 miles into the trail that has partially blocked access to the remaining 2 miles. The trail is passable with some scrambling through the damaged section, but does require sure footing. We hope to have repairs made on this trail soon, but rugged terrain and weather may make this a challenging repair.

Golden Mussel Advisories Affecting Boating in Napa County
Golden Mussels have recently been discovered in the Sacramento-San Joaquin Delta, the first known occurrence of this invasive species in North America. This type of mussel can survive in waters that have considerably lower calcium levels than needed for the other invasive species and are incredibly difficult to eradicate once established. They are also easily transported on boats or watercraft, so local agencies are implementing safeguards to hopefully keep them out of our lakes.
