Coming May 4 -6, 2012. Pinnacles National Monument gets its name from the rock spires that look like pinnacles, remnants of an ancient volcano. And, these pinnacles create an amazing playground for rock climbers at all levels. GirlVentures is sponsoring a fun and adventurous 3-day weekend for women interested in camping and climbing and learning about this amazing landscape just inland from Monterey, California. It’s your chance to travel back in time and experience the prehistoric world and make friends along the way.
