Roatán Island in $450s-$570s RT

Roatán Island might be off the coast of Honduras, but it couldn't be more different. The local language is a variant of English, and culturally it has more in common with its fellow Caribbean isles than with the mainland. 

That means it comes with the usual tropical thrills (like a frankly nutty amount of rainforest zipline options), but Roatán's biggest claim to fame is actually under the water. This is one of the best scuba spots in the entire world, for both skilled and beginner divers. You'll be exploring massive coral reefs filled with colorful fish, and maybe even some of these cute lil fellas!

Venture out further and you might even see a ghostly shipwreck appear out of the blue. That's the cargo ship Odyssey, and experienced divers can swim through all six of its floors and see how the ocean has slowly taken her back.
