When the rains start to hit the Isaan plateau, it’s time to pack your bags and trek out to Pa Hin Ngam and Sai Thong national parks in Chaiyaphum to witness the fields of blooming krajiew flowers. Also known as the Siamese tulip, dok krajiew blossom only during Jun-Aug of each year. The full bloom doesn’t take place at the same time at both parks, though. It starts at Pa Hin Ngam in Jun, then moves to Sai Thong in Jul-Aug. More information at TAT Nakhon Ratchasima 044-213-030, 044-213-666.
