I think it took an hour to get to the Tat Kuang Si by mini van. We hiked up to the waterfalls and swam on it. Really nice after walking under the hot sun. There are lots of swimming holes on the way towards the waterfalls. I recommend swimming as it's very refreshing after the climb. Bring swimmers!
You can book a ride on the mini van through one of the tourist agencies along the main street. It costs USD4 per person to get there and back. Otherwise, you can rent a tuktuk and share the cost with friends. Not sure how much the tuktuk costs.
P.S. A lot of other travellers recommended not going to Pak Ou Cave as it was just too touristy and nothing much to see.
