About VDiff Climbing
VDiff makes complicated climbing systems easier to understand.
VDiff covers everything from the basics of sport and trad climbing to self-rescue, big wall systems and glacier travel.
Most of this stuff is free, with books and more in-depth video courses for those who want to go further.
VDiff is a learning resource, not a replacement for experience or proper instruction.
