Once known as Thailand's Siberia because of its isolation, Mae Hong Son is an enchanting, tranquil retreat now conveniently reached by daily flights from Chiang Mai. Mae Hong Son is located amidst mountains, thus the province is living in fog all year round, enjoying a cool climate. A small town of Pai is exceedingly becoming a hit with backpackers and couples where they make the most of their time riding on motorbikes to thoroughly explore the region.
