Hi everyone, been a while but I am finally getting around to posting about this.
I asked about where to watch Muay Thai here: tripadvisor.co.uk/ShowTopic-g293916-i3687-k7… and got some very helpful replies.
Anyway, Ch7 was brilliant. For someone who doesn't really have any prior knowledge and doesn't want to fork out a load of money, really easy to get to, and a nice thing to tie in with visiting Chatuchak market on the Sunday.
Me and my girlfriend just went outside the exit of Mo Chit BTS station (opposite side of the street to Chatuchak market) and took a motor taxi for about 20 baht each. Very easy. When we got there, we just followed the people into the studios. We even got offered a free massage like the fighters get before their fight. Went into the stadium part and were shown the way to the seats (they had a section specifically for the few foreigners there), great seats, although it is small enough that sitting anywhere is fine. Felt very safe.
The atmosphere was great. Lots of locals getting really into it. I'd highly recommend anyone looking for muay thai to take a look if you're there on a Sunday.
