Abbreviations and Symbols

Useful Information

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.

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.
