Hpa-An is the photogenic capital and the largest and most populated city of Karen State (also known as Kayin State), on the Than Lwin river in Myanmar. About a 7-hour drive southeast from Yangon, the town is surrounded by Karst mountains and is great place for short, scenic treks. Outside of town there are seas of green rice paddies backed by Karst rock formations. Mt. Zwegabin is the most prominent “rock”, and can be climbed in a couple of fairly strenuous hours, but the views are a spectacular reward. The biggest draw of HpaAn for many, are the limestone caves in that serve as amazing natural Buddhist temple shrines.
