There are several Thai Boxing shows on Walking Street or just off it i.e. on Beach Road close to the entrance.
The biggest, and most popular, is located opposite the entrance to Marine Plaza about half way down Walking Street
on the right hand side if you are walking from the beach road end.
The video below is from the ring in the beer bar complex on Beach Road at the very end of Walking Street.
The fights tend to be very contrived, and nothing like as vicious as the real thing, but are quite good fun to
watch. Please not that is you request a photograph with a fighter you will be expected to tip.
