Covered with both high hills and low lying, forest covered plains, Nakhon Phanom is the site of Phra That Phanom, the most ancient and sacred religious monument in Northeastern Thailand.
In addition to its rich culture, Nakhon Phanom, which literally means “city of hills” is an area with great natural beauty and which features a number of opportunities for visitors to participate in outdoor activities, including trekking in the national park or shooting a round of golf.
