Nakhon Phanom, once the center of the ancient Sri Crow Ta Boon Kingdom, lies along the western bank of the majestic Mekong River, although over the centuries it has moved back and forth across the river.The lovely setting of Nakhon Phanom town is enhanced by the rugged beauty of the jungle covered mountains that lie beyond the town of Thakaek on the Laotian side of the river.
