Current Status of Parks & Trails 4/23/25
All parks not listed below are currently open for normal use.
Oat Hill Mine Trail – Please be aware of storm damage on the trail between Calistoga and Holm’s Place. There are several slides and places with erosion damage that are passable but warrant caution. NOSD staff is evaluating these areas for repair.
RLS State Park: Parking on the Table Rock side (east side) of the highway is closed temporarily but the Table Rock Trail remains open. Please avoid parking on that side while Caltrans crews continue repairs from recent storm damage. Limited parking is available on the Mt St Helena side (west) of the highway.
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.
