Guide Bio

Bill Mashek started his career at the age of 17 as a commercial guide on the Grand Canyon. From there he worked on rivers throughout western U. S. In 1972 Rubicon Adventures was started by Bill Mashek with a small group of whitewater boaters. Rubicon explored rivers throughout US, Mexico, Central and South America making several first descents. We are still the small company we started over 40 years ago and have expanded to an Adventure Travel company specializing in dive trips, whitewater travel, surf travel, volunteer and language learning travel. In 2007 we started Wine Country SUP offering Stand Up Paddleboard clinics and tours.
