Hide is just off Cliff Drive. Cache is available every day of the week, 11 - 6.
There's no dress code, but you might want to wear your long johns if it's really cold. You should narrow your eyes like a hawk for the search. Dogs are not allowed - especially black dogs. There's a modern-day doubloon for the FTF. You're looking for a small plastic container out of sight. No purchase or entry fee is required, and you don't have to enter any places of business. Accessible from sidewalk.
