As the name indicates, this caldera, which formed when a giant volcano exploded and collapsed on itself approximately 3-million years ago, is now the location of abundant wildlife due to its abundance of food. At an elevation of around 1,800 meter, the area of the crater floor is approximately 260 square kilometers. Within these confines, the lion population is reported to be the densest here (not that I saw a lot). The elevation of crater rim and the location of our lodge gets fairly chilly at night.
