𝗕𝗲𝗽𝗽𝘂 is truly one of its kind, the whole existence of this small coastal town evolving around the touristy gimmick of touring its "7 Hells". These "Hells" being hot springs, each possessing curious characteristics (or a pool full of alligators, when everything else fails). While not all of them were that impressive, it was a pretty fun and unique way to pass the day. I highly recommend.
