This cache is located in the San Jose Creek Trail portion of Palo Corona Regional Park. You'll need to apply for a day permit to access this section of the park. It didn't look like there were any caches on the Wilson Ridge side of the loop trail, and it seems like this side goes undervisited and underappreciated! This part of the trail is a few miles from the nearest parking lot, so be sure to bring enough water and snacks! You won't have to venture off trail to find this cache.
