Kirirom (Mountain of joy) National Park is a nice day trip about 100 km from the Phnom Penh and specially interesting is the Chambok Ecotourism site. Located in the Kampong Speu Province , this beautiful landscape was a visual treat. Do not miss the opportunity to sit by a river or a lake or a waterfall and experience the calm of the wilderness. There were tiny fish in the slow waters, kingfishers nearby waiting for their catch, the pine forests at a distance and loads of butterflies
