Nothing can be more refreshing than the Phnom Kulen waterfalls to cool off after a long hot day exploring the wonders of Phnom Kulen. Located farther downstream the first waterfall is 4-6 meters tall and 15-15 meters wide (depending on the season) and the second waterfall, hidden in a beautiful jungle scenery is 15-20 meters long and 8-10 meters wide (depending on the season).
