Discovering the Flora of Mount Shasta One Step at a Time
There are moments on every climb of Mount Shasta when you should stop looking at what is above you and start looking down. Not at your feet necessarily, but at the remarkable tapestry of life on the ground that somehow thrives on the flanks of California's...
The Life of a Snowflake
Last winter, while in Shasta one morning before an avalanche course I was instructing had started for the day. I found myself standing alone in the Castle Lake parking lot waiting for the sun to come up. It wasn't a particularly remarkable day. It wasn't the beginning...

SWS Mountain Guides Adventures are more then just reaching the Summit
We believe that every mountain adventure should be about more than reaching the summit. Since 1981, our focus has been on creating trips that help guests grow—not just as climbers, but as individuals. Whether you’re joining us for a guided climb of Mt Shasta, Mt Whitney, one of the many Eastern Sierra Nevada peaks, or heading out on one of our international expeditions like Everest Base Camp or the Mexican Volcanoes, our goal is to make sure the experience means something deeper.
As a long-established Shasta guide service, we offer more than just summits. We offer California based guided rock climbing, ski tours and descents, avalanche education, glacier training, backpacking trips, and international expeditions. We have designed every trip we offer to support personal growth, skill development, and to give back to the local communities and environments we work in. We believe a mountain trip should benefit more than just those climbing — it should have a positive impact on the surrounding area and the people connected to it. With our experienced guide team from California Rock Guides, California Ski Guides, and one of the original California Mountain Guides, we’re here to help you find not just the summit, but the story behind it. Whether it’s Bear Valley rock climbing, Mt Shasta’s Hotlum Bolam Ridge, or trekking in Nepal, we’ll help you take the next step. Find your next adventure with us — We believe the journey matters as much as the climb.
