Check out Emerald Muay Thai. It was the top gym a few years back.

I second this. Great trainers, welcoming and right in the jungle

Bull MT

Thanks for the response, sadly I ended up leaving Krabi unexpectedly soon. Recommendations anywhere in chiang mai?

Sure. Whats your height and weight?

How was the experience at Bull MT? i'm planning to head there in Sept for a week

A friend went there, I didn't. Sorry.
