Preduce Skatepark

I think it costs 60-90 baht to skate it for an afternoon/evening (I can't quite remember the exact price but it's pretty damn reasonable) and they have boards for hire available which are actually pretty sweet. The pictures are pretty average, the bowl is tight and small but still fun and the Euro is super nice. There are the standard rails and ledges and even a marble manual pad and bank. This place is also air-conditioned! You have no idea what a relief that is until you try to start skating in Bangkok.
