Nan consists of plentiful natural resources. Most parts of the landscape are mountains. Also, Nan is an important river source. Here we’re talking about Nan River, which originates from the north of the province, flows into Sirikit Dam in Uttradit Province, meets Ping River, and, finally, Chao Phraya River.
The weather there is also perfect. It has 3 seasons, yes. But, due to all those natural surroundings, there isn’t pollution. If you travel during winter, you can inhale the air into your lungs.
