You may want to think about a place to stay that offers an outdoor swimming pool if you're planning to visit Phumĭ Ândong Chénh in the driest months of February, January, or December when the average rainfall is 1 inches. Lodging that has a pool indoors may be the way to go if you come to town during the rainiest months of October, September, and August when the average rainfall is 8 inches.
