Cascade Range

3 Days

Feb, Mar




  • Summit the fifth tallest mountain in all of California at 4,322 meters.
  • Climb in the rugged and beautiful Cascade Mountains on the west coast.
  • Learn valuable techniques and tips from a knowledgeable guide.


Take on the indomitable Mt. Shasta and spend three days climbing the Casaval Ridge for a true winter adventure! This guided ascent follows a classic route to an excellent summit, providing practical instruction that will help you develop as a mountaineer and prepare you for a slew of future objectives!

Mt. Shasta, located at the southern end of the Cascade Mountains, is the fifth-tallest mountain in California. It’s 4,322-meter peak is also the second highest in the entire range. As a stratovolcano, it has developed into a complex geological objective for mountaineers because of its steep faces, glacier traverses, and high-altitude mixed climbing.

Your program will deliver you all of these climbing gems as you take three days to reach the summit. Following the popular Casaval Ridge Route, we will encounter steep rock faces, jagged ascents, and unbelievable views all the way up to the top. The ascent is perfect for intermediate and advanced mountaineers who have previous experience with crampons and ice axes.

The trip will start early from our offices, heading to the Bunny Flat Trailhead on the south side of the mountain. Snowshoeing to the base camp at Casaval Ridge puts us at 10,000 feet (about 3,050 meters) and ready to push for the summit on the following day.

For optimal conditions, we begin the summit day at around 2:00am with the intention of returning to the high camp by late afternoon. The final day is reserved for breaking down the camp and returning to the trailhead.

Our route will feature steep terrain and exciting technical maneuvers. The climb will combine a review and monitored application of techniques before putting them into practice on the challenging obstacles towards the summit. This is a great experience to propel you towards even taller objectives like Denali and the volcanoes of Mexico.

You should be in great shape for this climb and ready for multiple days on the mountain. Previous experience is necessary to participate in the program, as is the mental fortitude to be able to successfully complete this daunting ascent.

Book this incredible 3-day winter mountaineering program up Mt. Shasta NOW and follow the Casaval Ridge to one of the most exhilarating ascents in California and the entire Cascade Range!

Had an amazing experience! What memories but must be honest, we were in over our head. Feel we were physically up to it but we went from sea level to 10,000 feet in 30 hours and it was a challenge to keep up. Some time to acclimate would have made a big difference. The guides were careful and supportive. We were outside our comfort zone for sure but also realize that made it so memorable! Thanks Loren

I have summited some amazing peaks, but Mt. Whitney has stolen my heart. From her diverse landscape, to the ever changing appearance of her face each hour of the day; she is a wild beauty not easily put out of your mind. This Jersey girl hiked/climbed/scrambled-up/slid-down the Mountaineer’s Route, which was both physically and mentally challenging but, incredibly fulfilling. My guide, Matt M., was confident, extremely knowledgeable and skilled, and I am pretty sure part mountain goat. Best guide I have ever had, prettiest mountain I have ever been on; if you are considering this hike, I would say DO IT!

Fantastic guide service! I have skied with a number of guides over the years and I have to say that the guide we booked through SWS was one of the most knowledgeable, instructive and fun guides I have spent time with on the mountain. From the pre-trip communication all the way through the climb and ski down, I felt that I was in good hands, which was really important to me as my climb/ski partner was my 17 year old son. Our trip was epic, 4:00AM wakeup to a full moon, beautiful climb and huge ski down, my only complaint is that it was only a two day trip! Highly recommend, great experience!

Too bad this review does not allow six stars. SWS is professional, client focused, flexible, and has the clients best interests in mind. I can say the personnel and leadership skills of the SWS guides are among the best. You can't go wrong with SWS.

Excellent experience with my guide Ben and SWS. Was able to summit Mt Whitney via the mountaineer’s route thanks to Ben’s understanding of the mountain and assessment of my capabilities. Great experience that exceeded my expectations.

Overall, the fair evaluation for the SWS Mountain Guides and the guide assigned to me is 3 stars. Reasons: 1. The guide did not seem to remember or respect the fact that I was new to mountaineering and that the name of program is called “introduction to mountaineering...”. For example, the guide set his own time for walking and resting without any concern to my physical ability for that timing. The guide walked ahead many times and didn’t even notice when I fell a few times. I understand the guide is not the insurer of safety or a hand holder, but a complete abrasive approach to the service is not right, especially when it’s a paid service. Perhaps, the guide is not a right choice for introduction tours. 2. There was a miscommunication with timing of the summit day. I thought we would start summiting around 5am the next day; however, I was told less than 15 hours before that we would start hiking at 1am the next day from base camp. We arrived at base camp early afternoon, and I’m wired up, hot, and not prepared to fall asleep between 5pm-12am, thus, I didn’t sleep at all. I attempted the summit hike but around 12k feet the sleep deprivation was killing me and I was catching myself falling asleep and my body trying to lay down while waking. The guide didn’t seem to concerned about this. Lack of empathy. Eventually, I had to insist we turn around because I didn’t want to go beyond 30 hours of no sleep and still have to descend from the summit. 3. The guide did help set up the tent and food. The guide did explain layers of clothes on and off and why. The guide did help instruct how to pack and why. 4. Overall, I feel this guide is best suited for advanced climbers not introduction courses as he seems to be more of a “ill walk ahead of you” not “ill walk with you” type of guide.

Neil from SWS was amazing. We climbed the Mountaineering Route up to Mt. Whitney. It was an amazing experience. The guide was knowledgeable and friendly. I leaned a lot. I would absolutely use these guys again.

My guides name was Matt and we were lucky enough to summit Mt. Whitney during the winter. This was one of the most rewarding and fun experiences I have done and SWS did a great job throughout the process. Matt was such a great guide who took the time to educate us. He was polite, understanding and very helpful throughout the climb, I felt comfortable with him right from the start and look forward to more climbs with both Matt and the SWS team. Would recommend them to anyone!

Just finished my second trip with SWS Mountain guides...summiting Mt. Shasta a few days ago (previously climbed Mt Whitney last summer with SWS as well). This company provides excellent service both on and off the mountain, from addressing all my questions prior to the trip to establishing a well-rounded professional and fun educational experience during the climb itself!!!! Specifically, the guides on my trip were amazing, connecting with me on both a professional and personal level, keeping in tune with all aspects of the climb, emphasizing safety and education while helping me to fine-tune my climbing technique. Having used several different guiding services in the past, I have no hesitation to highly recommend SWS mountain guides!!!!
