The famous "Buddha caves" are north of the city on the Mekong and can be reached by road (approximately 1 hr) or river boat (around 1.5 hr). Alternatively, you can hire canoes and a guide for the day, which would allow you to view the beautiful scenery and visit the caves without throngs of other tourists. It's also possible to finish the trip at the "whisky village" where the local Lao lao (rice spirit) is made. There are two caves, one on the entry level and another, the upper caves, on top of the hill. A very steep climb, but worth the effort. A torch is needed to see the upper cave. Simply cross the river at Pak Ou village for 13,000 kip per person (25,000 kip if you're the only one on the boat), walk up the hill and turn right, crossing the school grounds, to find your way to the caves. Motorcycle parking at Pak Ou village 5,000 kip.
