This was a 2 day 1 night trip to Chet Sao Noi waterfall and Khao Yai National Parks. The Chet Sao Noi waterfall was much nicer then I was expecting with a nice swimming area on the level 4. After the waterfall we headed towards Khao Yai where we stayed the night and then the next day we headed into the Khao Yai National Park to see the famous waterfalls there. -- Pete
