Eight kilometers southeast of Phanom Rung is Prasat Muang Tam. It is believed to have been built between the 10th and 13th centuries. They have historical information available at the park. When we visited this and Phanom Rung Historical Park we rented motorbike taxis for the day, and they picked us up and dropped us off at the different parks and the bus station at the end of the day.
I loved the ruins at these parks.
