Cave World Map

About Cave World Map 🕳️

Cave World Map marks cave entrances around the world — show caves with lit walkways, wild systems known to cavers, and the dark openings in a hillside that most maps ignore.

Entrances are drawn from OpenStreetMap's `natural=cave_entrance` tag and added by cavers and locals. Caving can be dangerous: this map only shows where an entrance is, never that it's safe to enter — go with the right people, gear and permission.

Who is behind this site?

Cave World Map is built and maintained by Emil Björk, an independent developer based in Sweden. The site grew out of a passion for maps, travel and open data, alongside a professional background in IT consulting.

How it works

Every point is fetched from the OpenStreetMap Overpass API, deduplicated, tagged by country and stored as a static GeoJSON file — no database, instant to load. Click any point to see a description from Wikipedia, a photo from Wikimedia Commons (or Mapillary as a fallback) and, where available, its Google rating.

Data freshness

The dataset is automatically refreshed once a month from OpenStreetMap via a scheduled GitHub Action, so the map stays current as the world is mapped.

Spot something missing?

This map is only as complete as OpenStreetMap itself. If you know a cave entrances that isn't here, you can add it directly to OpenStreetMap — it's free, open and will appear here at the next refresh.

New to OpenStreetMap? See the how-to-tag guide for cave entrances. Edits show up here at the next monthly refresh.

Report an error or a wrong location

Found a cave entrances in the wrong spot, with outdated details, or listed twice? The data lives in OpenStreetMap, so the quickest fix is a short note there — a local mapper reviews it and the correction flows back to this map at the next refresh.
