Both Pak Ou caves are located about 25 km from Luang Prabang, where the Nam Ou River joins the Mekong. A journey by boat from Luang Prabang is approximately 1 hour, which is scenic and enjoyable with local fishermen casting nets and children playing in the water.
You can also opt for the road with a tuk tuk. This takes about 40 minutes between Luang Prabang and the village of Pak Ou. Arriving at the village, you should take a soonthaew (local canoe to) cross the river and reach the caves.
These caves are known throughout Laos and it is a very popular place for both tourists and pilgrims. Some 4,000 statues and statuettes are sheltered in these caves, especially images of Buddha, and most are covered with gold leaf. They take many different positions, including meditation, teaching, peace, rain, and reclining (nirvana). There are tow levels of caves: the lower overlooking Mekong River and the upper can be reached with a staircase. Make sure you bring a good flashlight.
