The following symbols are used to classify or categorize the links and on maps.
|Show caves are caves with well developed paths, mostly with electric light and regular guided tours.
They are open to the public, but only during certain opening hours and the visit costs an entrance fee.
The symbol used is the Greek letter Omega, which is often used on maps for caves, mainly because its shape resembles a Cave portal. The red colour means show cave.
|caves are natural, underground cavities that are large enough to be entered by humans.
Basically any natural cavity that is not a show cave falls into this category.
But showcaves.com contains in this category almost exclusively the following two types of caves:
|Springs are often associated with caves, they are then called karst springs. Every underground cavity is of course a collection conduit and a path for groundwater. The largest springs in the world are karst springs, in other words cave rivers that reach the surface at the cave entrance or resurgence. So it is logical to describe the largest and most beautiful karst springs in the world on showcaves.com. The symbol used is a blue circle, which is also often used on maps for sources.
|Karst Features are geological phenomena that are typical of karst areas.
Apart from caves, there are many interesting things worth seeing, such as sinkholes and swallow holes.
The symbol used is a circle with radial lines, which is often used on maps for depressions, such as sinkholes.
|Show Mines are abandoned mines, which are developed with concrete trails, light and guided tours to give the visitor an insight into the work of the miners.
They are open to the public, but only during certain opening hours and the visit costs entrance fees.
The symbol used is the miners' sign for a mine, mallet and iron. The mallet is used as a hammer, the iron as a chisel with a handle. Miners worked with these two tools for centuries. It is also used on maps.
|Subterranea means any kind of artificial or man-made cavities and related museums.
The most common ones are cellars, tunnels, catacombs, speleological and mining museums.
The symbol used shows a tunnel entrance, a symbol that is often used on maps.
|This are links, which leave showcaves.com.
We try to add as many external links as possiblle, especially if there exists an official site, which means a site made by the owner of the cave. We mark them with a small planet Earth symbol, which tells you that this link will lead you to the rest of the world....
In the last years several strange judicial decisions made it necessary to point out the following: We are linking only to sites about caves, mines, geology, and sometimes tourist sites. However, we have no possibility to ensure the content of pages that are not maintained by us. It may always have changed since our last visit.
By following any link leading out of this website, you accept, that showcaves.com is not responsible for the content you may find.
|The book symbolizes a Literature link.
We tried to list as many interesting books about the topic of this site as possible. A link with the book logo will lead you to the named book. The book logo usually takes you to a literature page or to a page on the internet that concerns a book on the topic. This can be online versions of public domain books or a shop that sells the book. Sometimes it is also used without a link for a literature reference.
