Picture yourself off the coast of Southern Chile, sailing the Chonos Archipelago. Okay, so if images aren't springing to mind, we can paint you a picture: this is a string of islands mostly covered in forest, and almost all are uninhabited. The waterway you're sailing is an offshoot of the Aysén Fjord and is called the Darwin Channel, named after — you guessed it — the famous biologist and naturalist who explored this region before it became popular. Oh, and let's not forget to mention that those islands are actually the peaks of mountains — it's just that most of the Chilean Coastal Range lies underwater. If this is all sounding cool to you, you need to come and see it for yourself on a Carnival cruise.
