Every outdoor climber should be proficient in anchor building and breakdown, so let us help you get there! Onto Stone’s basic anchors course covers bolted anchor set up and breakdown, trad anchors, natural anchors, and has plenty of time for practice and critique! We limit our courses to a max of three students to allow for more personalized instruction, so sign up today before space runs out! If July 15 fills, reach out or check back soon for August dates 🧗‍♂️

As a climber I've always felt it was important to be a part of the organizations which help protect wild places, and our access to them. Now, as a small business owner, I feel it's even more important to give back. Onto Stone was proud to donate a 6 hour custom climbing course for 2 to the Allied Climbers of San Diego fundraiser last month. We encourage everyone to be active in supporting our local climbing organizations!

When I first started climbing 30 years ago, I had no idea how much work went into finding, cleaning, and developing the routes I climbed. Over the ensuing years I've had the privilege of participating in many FA's, and I now understand first hand how much blood, sweat, tears, (and money!) go into every new route. But it never gets old, and I still love a day of good old fashioned adventure, exploration, and type two fun with my friends!


Nobody likes a cluster at the anchor (especially the people trying to come up behind you). We can help. Onto Stone offers 6 hour anchors courses for $125 with a 3:1 student to teacher ratio. Learn anchor site analysis, gear selection, rope management, and more. Mention this post for 10% off an anchors course.


Mother Nature can be unpredictable. This day at Tahquitz started off without a cloud in the sky! What would you do if bad weather rolled in during a multi pitch climb? What if rockfall injured your partner and they were unable to continue? Come take a self rescue course with Onto Stone! Ground based Self Rescue courses are 6 hours long and priced at $125 per person, max 3 students per class for lots of personalized attention. Mention this post for 10% off.
