You can follow an old road up here, past old foundations and farm land. Staying on the old road, past a couple of left turns, and going past Sky Pines Farm is the nicest way -- the trail does loop back down to the old road.
You'll be looking for a small brown container placed in a way appropriate for the Sky Pines name.
This is in the Pleasant Valley Reservoir area. It's a short hike from the parking place. You can park at the gate on Gulf Road, off Sunset Lake Road, don't block the gate. Head in and look for the old road (a bit stream bed like, at times) heading westward and up.
Gulf Road is now gated, but I remember when it was a public road. We used to drive in and then go four-wheelin' up to Sky Pines. It's still a good place for a hike or mountain bike ride.
