Can't miss the Phimai Historical Park

I've been to Korat (a.k.a. Nakorn Ratchasima) twice to visit the Phimai Historical Park which has one of the most important ancient Khmer temples of Thailand. Getting Phimai was not so very difficult. From Bangkok, I caught a train to Isaan district. It took five to six hours. I enjoyed the great scenery from the train windows and had a Thai styled lunch on the train. Then, I got out of the train at Nakorn Ratchasima that the place I was able to find a clean cosy hotel easily. From there, I took a bus to Phimai. It took about one and a half hours or so. I think it was a nice one day excursion from Nakorn Rachasima. Also, it's a can't miss place in Isaan, Thailand.
