Take the Engelsmans Loop, which is the first left after you pass the old wooden bridge. The cache is hidden just to the east of the Engelsmans Loop trail. There was no poison oak sighted in the area.
Getting There
The best bet for parking is at the main parking lot at Wilder Ranch State Park, especially if you plan to be out for a while. It’s safe and it supports the park system. From there walk to the farm then under the walking ‘underpass’ out into the inland side of Wilder. RECOMMENDED PARKING: N36 57.618 W122 05.131 with a State Park pass or $10 parking fee.
Alternately, you can park on Highway 1 (for free) near the underpass and drop down onto the path below via the de facto trail.
PARK RULES: Open 8:00 a.m.to sunset daily. No dogs allowed. Obey all warning and sensitive habitat signs.
