The Vasco Caves Regional Preserve is located near Brentwood, California. The site, which includes some interesting geological features and a few pictographs, is accessible by guided tours only. For more information visit the parks website or call the guided tour phone number 1-888-327-2757.
Included with this post is the GPS file and map that we plan to use for our first visit. If you don't want to wait for us to get around to it feel free to try the GPS file and map for yourself. With no guarantee, of course, but they most often prove valuable for us.
