The Hole-y Guide to Climbing, Highlining, Caving and Canyoning Bolts
Install, Remove, and Understand What You're Trusting With Your Life
Welcome to the 5th edition of The Bolting Bible! It now encompasses the 4 main sports that use bolts with 500+ images, 250+ links, 60+ HowNOT2 videos, and 450 break tests. It is no longer a PDF as our new blog version allowed us to double the content and keep it maintained. The Bolting Bible will easily guide you down any rabbit hole you choose to explore or you can find something specific using our filter system on our CONTENT page. There are 16 chapters. The first 12 are the "Old Testament" with general information and chapters 13-16 are the sport-specific things you need to know. Even if you never plan on installing a bolt, I encourage you to scroll through and spend an hour learning about what you trust with your life.
