For several decades the German cavers offer an international training camp for young cavers, called JuHöFoLa. The camp has been very popular among German and east European cavers. The first attended because of its good value (250 € for two weeks including meals and all materials and transportation), the latter for the possibility to escape the iron courtain for two weeks and the chance to find someone to marry.
But like many traditional leisure activities caving has nowadays problems in finding interested youths. Most are pretty busy using their cell phone and working to pay the cell phone fee. And the eastern countries are now part of the EU and borders are open. So last time the camp was skipped the first time after 20 years because of too few applications, and this year the camp is much smaller. It is pretty sobering if you learn that many attendants were not really interested in the topic.
However, there is still the possibility to attend the camp. Some courses are booked but others still have vacancies. The camp is international, the only requirement is to understand English (or German of course) and if you are not of age a signature of your parents.
The geology course has still some vacancies. It will include an introduction into the geology of caves, of southern Germany and its escarpments, volcanism, the biggest meteor crater in Europe (25km in diameter) and fossils of the Mesozoic including some world famous fossil collecting opportunities. It will include a little practice in using maps and GPS, surveying, work with geologic compasses, preparation of fossils and work with cave sediments. There will be a little caving, but nothing difficult. Of course there are so called free days, where you may choose to visit a cave.

Ah, and by the way: I will be one of the course instructors for geology.
