Very detailed guide: http://paragliding-lessons.com/article/Mussel-Rock-Site-Guide.htm Please carefully read the Bay Area pilots advisory (link below) - we don't want to lose this site due to blowbacks or problems with neighbors. http://www.sfbapa.org/pg/sites/dump/advise.html There's a nice crowd of local pilots - ask a local for a site intro before flying. We're happy to help.
