Short for 'topographical', borrowed into climbing for route diagrams.
A topo is a diagram or annotated photo that maps out a climbing route, showing its line, pitches, belay stations, protection, and grade. Found in guidebooks and apps, topos help climbers find and follow routes on the rock. It should not be confused with a topographic map used for navigation.
How to read one
Trace the marked line upward, noting pitch breaks, belay anchors, gear symbols, and the grade — check the guidebook’s legend for the symbols.
Not a topo map
A climbing topo maps one route; a topographic map maps the landscape for navigation.
Frequently asked questions
What is a topo in climbing?
A topo is a visual guide to a route — a line drawn on a photo or a schematic diagram — showing where the route goes, how many pitches it has, where the belays and bolts or gear are, and its grade. Climbers use topos to identify and follow routes on the cliff.
How do you read a climbing topo?
Follow the marked line from the base upward, noting pitch breaks and belay stations, symbols for bolts or recommended gear, the grade of each pitch, and features like roofs or cracks. Symbols vary by guidebook, so check its legend.
What's the difference between a topo and a topographic map?
A climbing topo diagrams a single route on a cliff; a topographic map shows the contours and features of a landscape for navigation. They share the 'topo' root but serve completely different purposes.
