About VDiff Climbing

VDiff is a learning resource for rock climbing.

VDiff explains climbing systems clearly using diagrams, videos and step-by-step guides, making complex techniques easier to understand and apply safely.

Content is available as free articles, e-books by donation, paperback books and more in-depth video courses.

A wide range of climbing skills are covered; from the absolute basics to advanced self-rescue and big wall systems.

VDiff aims to support learning, not replace experience or professional instruction.

All VDiff articles, illustrations, books and videos are made by Neil Chelton. These are reviewed by guides and instructors to ensure safe and correct information.

Neil became a rock climbing instructor in 2003, and has been a climbing fanatic ever since. He has spent most of his adult life living in a van, tent or portaledge. He has climbed many big walls around the world, up to A5 in difficulty, including solo and first ascents. He currently lives in Squamish, Canada.

This is why he likes to climb big rocks.
