Magnificent and impressive natural cavity that can be explored with a lamp. At the bottom there are beautiful ice formations even in summer. This phenomenon is due to the shrinkage of the cavity which traps cold air at the bottom. When moisture seeps through the ceiling, the temperature is low enough for the water to freeze and form stalactites.
