Climbing gyms with thousands of routes, boulder halls for an after-work session, and real outdoor crags for weekend trips.
This map shows three related but different worlds: indoor climbing gyms (with rope, tall walls, thousands of routes per gym), boulder halls (max 4 m, no rope, thick mats, perfect after work), and real outdoor crags — from sandstone in low mountains to alpine granite. The popup shows difficulty (UIAA in DE/AT, French in FR/ES), route count, and rock type. Use the filters above to toggle indoor and outdoor.
Looking for a gym for after work? A crag for the weekend? Planning your first multi-day trip to a climbing area? The map combines indoor gyms, boulder studios, outdoor crags, and alpine routes in one view. POI popups show grades (UIAA, French), route count, rock type, and opening hours where the community recorded them in OSM.
UIAA (Germany/Austria/Switzerland, Roman numerals): I easy, V medium, VII demanding, X+ elite. French (France, Spain, many gyms worldwide): 3a easy, 5c medium, 7a advanced, 9c world-class. Boulder: Font scale — 4 easy, 7A advanced, 8B+ top.
The popup shows the min/max range, if the gym or crag recorded it in OSM. A UIAA gym from V- to VIII+ covers beginners through advanced climbers. Outdoor areas are often more specialized — Frankenjura is famous for high grades, Saxon Switzerland has its own scale, Spain (Margalef, Siurana) covers everything from 5a to 9b.
The map queries OpenStreetMap live (Overpass API). The following tags are evaluated:
sport=climbing — main tag for any climbing facilityclimbing=route_top_rope|sport|bouldering|... — subtype — bouldering, top rope, sport (lead), multi-pitch, alpineleisure=sports_centre + sport=climbing — classic climbing gym, often with both boulder and route sectionsclimbing:grade:uiaa:min/max + climbing:grade:french:min/max — difficulty range in UIAA and French scales — rendered in the popupThis map runs entirely in your browser. Your location is never sent to our servers — it's only used to center the map. Map data comes from OpenStreetMap.
All points come from OpenStreetMap and are fetched live via the Overpass API. Something missing or wrong? Anyone can fix it directly on OpenStreetMap — the map will reflect the change shortly after.
Climbing lives by spots: a bouldering gym, a classic sport-climbing crag, a trad line on the coast. Specialty platforms like The Crag or UKC collect route topos with grades but they are not public or require login. Our map uses OpenStreetMap as a common data source and shows three types in one view: indoor gyms, outdoor spots and bouldering-only areas. It answers a question almost every climber knows — "what is in this region anyway?" — without login and without an app install.
Especially handy is the combined indoor + outdoor view. In winter you see gyms like Magic Mountain in Berlin, Boulderwelt in Munich or the Stuntwerk chain; the same map in summer shows that 60 km west there is a climbing garden in a disused quarry. Via tags like climbing:rock you can filter rock type (limestone, granite, sandstone) — important for route selection, friction behaviour and friction management.
OSM also carries grade information per spot — as min/max in UIAA and French scales. In the popup you immediately see whether a crag suits beginners (UIAA III-V) or pros (UIAA IX+). Combined with the strong tradition of local climbing groups maintaining their spots in OSM (e.g. Frankenjura with the German Alpine Club, Fontainebleau with French boulderers), you get a map astonishingly close to reality.
How climbers use the map:
Data comes directly from OpenStreetMap, licensed under the Open Database License (ODbL). We pull it live via the Overpass API every time you move the map, so you always see the latest state. OSM edits usually appear within minutes. Did you visit a spot that is currently closed (nesting birds, climbing ban, nature reserve), or learn about a new gym? Update the data on openstreetmap.org. The OSM Wiki has a detailed entry on climbing tagging under Key:climbing.
We are as good as OSM. Well-mapped regions like Fontainebleau, Frankenjura, Saxon Switzerland, Mallorca or the Swiss Alpine foothills are extremely densely covered. In remote mountain regions or outside Europe density depends on local initiatives. There are inconsistencies between tag schemes (e.g. climbing=* vs sport=climbing) — we catch the most common ones, edge cases may be missing. Also: an OSM entry says nothing about legal access. Always check regional Alpine Club info or local climbing bans before climbing.
climbing:grade:uiaa and climbing:grade:french support both views.highway=via_ferrata or route=via_ferrata). Our map focuses on spot POIs (gym, crag, boulder block). For a complete via-ferrata overview we recommend viaferrata.org or the DAV/CAI apps.sport=climbing, add climbing=sport|trad|boulder|toprope and ideally climbing:grade:uiaa:min/max. Mind legal aspects: only add spots in nature reserves or on private land if climbing is permitted. When unsure, talk to the regional Alpine Club or local climbing association first.
