Welcome to Bay Islands
Diving here is very affordable, but lodging and food on the islands can be more expensive than on the mainland. Low-key Utila is the fun, budget island (and very popular with backpackers), while Roatán is much, much bigger, has better beaches and and is decidedly more sophisticated. Diving is also good on Guanaja, though costs are far higher here than the other two islands.
The rainy season here runs roughly from October or November to February. March and August are the hottest months; at other times sea breezes temper the heat.
