 In January 1994, the reserve was finally converted into a national park, although timber harvesting continued in some areas.Together with the fauna and flora, the park has a variety of scenery; this includes cliffs, caves, waterfalls, gorges, mesas, calderas, hot springs, and the mountain peaks.The most popular areas are the four explorable, vast caves where frequent night visitors such as elephants and buffaloes come to lick the natural salt found on the cave walls.
