Welcome to Lynnville Park. There is a $2.00 entrance fee to get in. Plenty of caches here, as well as camping, fishing, and hiking.
You are looking for a Loc-N-Loc container. Log only. BYOP. Please put back as found. There are many motorcycle trails here that can be very useful in your hike to the cache. I'd use them to get close. Then take the right ridge to the cache. Good luck!
