NOTE: To hike on these trails, you must obtain an EBMUD hiking permit, which is available here.
Take the well-defined trail to the Rocky Ridge Trail Intersection cache (GCZ1QN), which has a 900-foot elevation gain from the Bollinger Road parking lot, then head west on a short and mostly level trail to this geocache. This morning (19 Oct 2013), the hike took me 32 minutes from the parking lot to this cache.
The cache is in an easy-to-reach spot -- no rock climbing required.
