Deep in the woods, bring a compass. Bushwhacking required.
The White Rock Geocache can be used as a starting point, but it can also be accessed from the Bear Paw atv trail to the north if you want to bike part way there. Bring bug dope if you're planning on attempting this in early summer. A compass is a good idea, lots of ridges and dips to get turned around in. Beware of old logging trails, some lead to the cache, some peter off into nowhere.
