The Tourism Authority of Thailand (TAT) is using its Discover Thainess campaign to attract foreign tourists to "Hidden Gems" -- 12 provinces most people miss on their trips here.
The provinces are Lampang, Nan, Phetchabun, Buri Ram, Loei, Samut Songkhram, Ratchaburi, Trat, Chanthaburi, Trang, Chumphon and Nakhon Si Thammarat.
The Bangkok Post has already looked at the tourism potential of nine of them. The 10th hidden gem is the northern province of Nan, 669 kilometres from Bangkok.
