Mountain Adventure Seminars

We’re excited to announce that Mountain Adventure Seminars (MAS) and SWS Mountain Guides (SWS) have combined guide services, along with our sister companies California Ski Guides (CSG) and California Rock Guides (CRG), to give you more mountaineering, skiing and climbing adventures, courses and clinics than ever before in California! By blending the same fantastic courses, climbs and service offered by MAS with SWS’s large venues – from Mount Shasta in the North to Mt. Whitney in the South – your outdoor adventure possibilities are endless!

SWS was founded by Timothy Keating in Mt. Shasta in 1981 and is celebrating 36 years of guiding adventure lovers into the California wilderness. MAS was founded in Bear Valley in 1996 and brings 20 years of outdoor adventures to our guiding family.

SWS is led by Timothy Keating, David Cressman, and JB Brown and is a reflection of their love for the outdoors and enthusiasm for introducing, sharing and educating others in “the wild places.” The main office and bunk house are located in Mt. Shasta, with additional offices in Lone Pine and now, Bear Valley, California.

“We are thrilled to bring Bear Valley and all MAS courses into the SWS family.”

MAS/SWS NOW operate the broadest range of programs in the most venues in California of any guide service: Mt. Shasta, Mt. Whitney, Mt. Russell, Pinnacles, Castle Crags, Alabama Hills, Crystal Crag, Bear Valley, Lover’s Leap, Calaveras Dome, North Palisade, Temple Crag, Mt. Sill, The Incredible Hulk, International Expeditions and much more!
