Depart this morning at 7:30 am. It is situated in Kampong Speu province and was the first to receive national park status in Cambodia. You will follow Highway 4 all the way until you reach the Kirirom junction from where the road becomes slightly bumpier. Take a turn first towards Chambok community and explore one of Cambodia’s first community based tourism projects. Enjoy a 30 minute trek through the forest to the Chambok waterfall and enjoy your picnic lunch (own arrangement from Phnom Penh). And then, you will pass through the gate of Kirirom and drive all the way up to the top to admire the views of the surrounding forest and mountain ranges at 675 meters above sea level. Take a stroll along some of the many trails towards the lake (20 mins). The pine forest is of particular interest and offers a relaxing walk and there are numerous streams and rapids in the park to be visited as well. Return to Phnom Penh mid afternoon after a refreshing day in the national park.
