From the outside, this small and romantic resort is just a cluster of ordinary bamboo huts with thatched rooms, but once you step inside you realize that these huts are special. Devoid of brand name decorative items and expensive furniture, Phu Chaisai chose to build with decorative items. The air is just one of the many attractions of Phu Chaisai (Mountain of Clear Hearts), an enchanting little “boutique” resort located in the hills outside of Mae Chan, in Chiang Rai.
