Eisriesenwelt was formed by the Salzach river, which slowly eroded passageways in the mountain. The ice formations in the cave were created by thawing snow that drained into the cave and froze. This section remains icy even in the summer because the cave entrance is open year-round, leaving it exposed to chilly winds that keep the temperature below freezing. New formations appear each spring, however, as water drips into the cave and freezes. Eisriesenwelt means "World of the Ice Giants" in German.
According to UNESCO, the Škocjan Cave is among the largest underground canyons known worldwide. It is a combination of natural beauty with enormous aesthetic value. Being home to a diverse ecosystem, it is historically and culturally significant. Škocjan Cave was inhabited during prehistoric times.
This cave was formed under the twisted layers of rock at the bottom of the Aezkoa valley. The cave is believed to have been utilized as a refuge through the ancient era for shepherds. The unique formations and rich colours make Cueva De Arpea a must-see for adventure seekers.

The Puerto Princesa Subterranean River National Park is one of the New Seven Wonders of Nature and a UNESCO World Heritage Site. The river is home to many marine creatures. The entrance to this cave is a short hike from a nearby town. The river in the cave is navigable by boat for up to 4 kilometres, but it is impossible to explore any further.
On top of being my personal favourite, this cave is a major tourist attraction and is famous worldwide. The glowworms are the size of ordinary mosquitoes, and millions of them abound inside the cave. They are monitored closely by specialized staff from a scientific advisory group that uses automated equipment to monitor the cave remotely, including the temperature, the amount of carbon dioxide (needed to maintain the glowworms), and the number of visitors that can enter each day.
Carlsbad Caverns offers numerous programs for tourists. One of the most popular ones is the Bat Flight Program, where tourists can witness the bats' sunset flight out of the cave and their sunrise flight back in the following morning. Camping is also allowed, provided campers have a ticket from the National Park centre. The latter was first thought to have no bottom because stones thrown into the pit made no sound. Later they found out that it is only 140 feet deep and has a thick layer of soft dirt at the bottom, which is why it doesn't make a sound when stones land.
