We went with a tour company and paid 1000 BAHT each for what was in essence a round trip of 4 hours in a minibus. The scenery is beautiful at the top as are the waterfalls, but not worth what we paid. Lunch was OK, but we had very little time to look around the beauty spots. It appeared very controlled and we did not see any trails that you could go on for several hours. If we were to do this again (most unlikely), then we would either hire a car or taxi and spend time where we wanted to. There are explanations everywhere so the services of a guide are unnecessary.
