Just got back from Thailand on 25 June 2013. Cost 200 baht to get in, but you must be there at 14:30 or 2:30 pm to see the snake show. If you miss this you will have pretty much wasted your money as it was the highlight. The static displays and live snakes in cages were good, and be sure to go into the white building as there is two floors of displays there. A King Cobra being handled and displayed 1 metre from you was awesome. What a large snake!
