Set in high limestone cliffs above the Mekong River, at the point where it meets the Nam Ou River from northern Laos, are two sacred caves filled with thousands of Buddha statues dating from the 16th century. The lower cave, Tham Thing, is accessible from the river by a stairway, and has enough daylight to allow you to find your way around. The stairway continues to the upper cave, Tham Phum, for which you need a flashlight. The admission charge of 20,000 kip includes a flashlight and a guide.
The town of Pak Ou, across the river from the caves and accessible by ferry, has several passable restaurants.
