Lower your expectations for what paying a premium for "ringside" seats will get you. Though they're better than the cheap seats, It's still first come, first serve for the few hundred ringside seats.
Authentic place for those who like not only tourist roads. Interesting atmosphere around. And the best fighters. Tickets is around 1500-2000 bath, but it worths!
Don't get hustled if you're a farang; matches should run you 2,000 Baht for ringside tickets. Don't pay any of the touts farther from the gates offering higher ticket prices!
