Paying 200k for two people we set off to the Pak ou caves along with two Swiss girls. The trip took 2-3 hours with a stop off at the whiskey village. A dirty dusty little village that does not really leave much to the imagination. The caves are filled with thousands of Buddhas which is cool however the caves really aren't that spectacular and with 15 minutes we were back on the boat heading back. The boat ride was enjoyable but I would say if you are on a small trip to LP there are plenty of better things to do with your time.
