Ang Trapeang Thmor located in northwestern Banteay Meanchey. It is approximately 100 km from the town of Siem Reap. Ang Trapeang Thmor is a unique wetland ecosystem and is home to over 200 bird species, including the endangered Sarus crane.
This swampy water reservoir was constructed by forced labor in the Khmer Rouge period. The southeastern corner of the lake also acts as a resort for locals where the boats, rubber rings and food are available.
Visitors can enjoy both the wetland ecosystem with scenic views and the beauty of the Lake District. For those who want to do something then paddling on the lakes is a good alternative. Ang Trapeang Thmor also provides the ability to view the ancient Cambodian culture with its ancient temples. Last but not least Ang Trapeang Thmor is also famous for its Eld deer spotting. At the height of the dry season - March and April - herds of endangered Eld's deer are feeding themselves on the edge of the lake.

The endangered Sarus Crane feeds on plants, but also insects, lizards and mollusks. Unlike most crane species this species has adapted to human beings pretty well. He feels at home in rice fields or between cattle, where he catches frogs and other small animals that are hunted by the cattle.
The population of the Sarus Cranes in this area increased constantly in recent years.

There is currently a project in Ang Trapeang Thmor in order to prevent the rare birds disappear. Birds can be seen all year round, but the best time to view the Sarus Cranes is from February to May.
Siem Reap Town is two hours away in the dry season and a three-hour drive during rainy season with minibus, taxi or motorcycle taxi. To visit in the wet season the reserve, it is advisable to do a 4-wheel drive.

Eld's deer

There are quite a few poachers in the reserve. Hence, regular, intensive patrols instead. These patrols have been increased in recent years.
