Park in the upper parking RSF parking lot on Skyline Drive and take the white blazed (Todd) trail on the other side of the road. The trail makes some slight twists, but generally goes in the direction of the cache. The trail skirts the Camp Tamarack and Camp Todd properties. These are defunct Boy Scout camps that have been recently purchased by the county (see my note in the logs below).
Please keep the cache well hidden, as this is a popular party spot.
Note: I noticed a Letterbox (www.letterboxing.org) nearby during a maintenance visit. Looking through the Letterbox log, it appears that some Geocachers have also found the Letterbox. The Letterbox is clearly marked as such, so you can easily tell whether you found the cache or not.
