Australia
Christmas Island is an idyllic Australian destination home to exciting wildlife species like the coconut crab. They sound cute and tropical, right? Wrong! These monsters can grow up to three feet and are found, not just on beaches, but in the trees as well. Sounds more like a horrific sci-fi film than Christmas!
There are plenty of other safe activities for tourists to enjoy on Christmas Island but seeing the crabs travel during their annual migration to the coast is the main event. It's no mere bird migration. Over 40 million of these crabs used to live on the island! So it's quite the exodus for the crabs. Unfortunately for them, travelers often crush the crabs while driving, so Christmas Island had to install barriers, bridges, and underpasses for the crabs to funnel through.
