Sea of wood Samuth Cheu is located northwest of Sen Monorom in the Phnom Doh Kramom area. "Samuth Cheu" is a special place that tourists do not forget to visit when they reach Mondulkiri. From the top of the mountain you can see a beautiful view of the forest, mountains, valleys and hills, seen from a distance like green waves. That is why the sea of trees is called the sea of trees. The site is also decorated with a bridge for photography and a coffee stall.
