Walking to the tuk tuk line on our way to a club in Boracay, Philippines we saw a spa advertising those fish that eat the dead skin off your feet. The next day we headed back to try it out. I’ve seen it before in other Asian countries, but never actually tried it. It’s a strange concept, and I don’t know that I could tell the difference afterwards (and my feet were all messed up from climbing Mt. Whitney), but it was worth trying.
