Bay Islands, Honduras
Utila
A small Caribbean island built almost entirely around cheap, easy diving and a laid-back backpacker scene.
Utila is the budget end of the Bay Islands: a single small town strung along one main street, dozens of competing dive shops, and a long-running reputation among backpackers as one of the cheapest places on earth to get PADI-certified. It draws a younger, longer-stay crowd than Roatan's resort scene -- people who came for a week and stayed a month once they started diving. The pace is unhurried and the island itself is small enough to get around on foot, bike, or golf cart.
