All caverns on this site are grouped by countries, which means political borders. You are able to zoom from the World map to continents and then to country maps, where the caverns are marked.
The maps are active. Just click on the place you're interested in. The highest resolution maps show the caverns, either with name - if there is enough space - or with a number. There is always a textual link for each graphic link too, but there is also a text-only index.
Unfortunately it is a lot of work to make those clickable maps, so many are still missing. Some of them are old and do not follow our current "corporate identity". We hope they are helpfull anyway.
