Jaskyňa+mŕtvych+netopierov (Cave of the Dead Bats) is named after the remains of thousands of bats, found in the cave. The temperature is very low and the cave is very windy, so it is not very suitable for hibernation. The chillness costs the bats too much engery and so many starve during winter, as their body fat is not sufficient. The oldest found bat skeletons are 6,000 years old, and every year new skeletons are found.
The cave is not really a show cave, although the Speleo Club Slovakia is advertising it so. All in all the one hour walk to the cave and the spelunking-like tour make it an experience for the phsyically fit and adventurous cave visitor. The short tour is equipped with light and the paths are prepared, but it is still a very rough, not to say hair-raising, cave experience. The minimum age of six should definitely be taken serious. Lighting is powered by a petrol generator in the cave house, where the guides live while on duty during summer. There is no vehicle access: petrol and all other supplies are carried up on the guide's back.
If the short tour is not enough, there are longer tours, which are real spelunking tours. This means caving gear, light, physical fitness and a little experience. The visit of the short tour is the precondition for those tours. The longest tour is a day trip to the biggest hall of the cave, Bystrický dóm (Bystrica hall).
The mount Dumbier (A=2043m asl) is the highest mountain of Nizke Tatry, the low Tatra. The area is a popular hiking area with trails, cable cars and a ski area to the west. The limestone is a package of less than one square kilometre and about 350m thick. This whole volumed is karstified, and most of it is filled with the 12 levels of the Cave of the Dead Bats.
The cave is rather exceptional, as there are numerous places with abundand speleothems despite the high elevation. Even more interesting are lava intrusions into the limestone, which can be seen on all tours, including the so called tourist part. The lava entered the rock following cracks and clefts, which may be of karstic origin. This means, the lava filled very old caves of a so called paleokarst, a karst which formed much earlier than todays caves.
