Abbreviations and Symbols


All pages on this site, that describe a tourist site, have a first paragraph with the heading Useful Information. This paragraph gives relevant facts about a place in a compact form. The font is smaller than normal and there are many abbreviations and symbols used, to keep it as short as possible. This are the hard facts of every destination.

Unfortunately much of this information changes rather often. Be aware that open hours and fees may change without notice, so we are not informed. Sometimes even the dimension of a cave changes, as new parts are discovered. I you need current information, use the address/link and ask. If you find any errors, please send them by e-mail.


Every category on is represented by a simple symbol or logo. Those logos are mostly derived from symbols used in topographic maps. Such symbols differ widely from counry to country and even from map to map, but we used symbols as they are common in German maps. Their meaning is to show the visitor which category a certain site has.
