Did you know that there are a number of significant underground caves all over the world that are not only beautiful and adventurous, but they also  hold a great amount of history too.  From the Mulu Caves to the Skocjan Caves ( the highest cave hall in Europe), and  the Waitomo Caves in New Zealand. The cave was formed over 30 million years ago (WOW) and it is the home to the famous Waitomo glowworms…..these worms are the size of an average mosquito… yikes. But the cave is beautiful

Below is a link to some of the famous caves tours… enjoy!!
