La Fortuna, Costa Rica
Caveat Emptor.....the water slides at Baldi Hot springs are crazy! If you ever go there....and you should if you're in Cosat Rica (25 pools of differing temps, 3 swim up bars, whats not to love???) one of the slides you get to serious speed. No warnings posted, no lifeguards on duty, its a crazy ride. There are 3 slides, I'm not saying which one is the killer, you'll have to guess and find out but a tip, ensure the togs are firmly fastens before hitting the slid...
