Vientiane to Luang Prabang is just a short flight, but having flown this route before I looked out of the window and thought it must be awesome to be down there! Since we had to get to the mountains of northern Laos, some 150 km north of Luang Prabang, renting a car with a driver was the best choice we ever made. The 4-5 hours drive quoted by google maps is a total illusion though. With just minimal stops and a reckless driver it took us almost 14 hours for the whole drive. There is almost no traffic, but THOUSANDS of pot holes, winding roads, street work which is not worth to call it "construction", but it is an AWESOME drive and one of the most picturesque places on earth!
