Corcovado National Park, Costa Rica
This nature preserve is full of a certain winged species—vampire bats. (The critters thrive on blood for nourishment, but they actually thirst for cattle.) Spot them on a tour through the lush jungle. Vampire honeymooners can beat the crowds by opting for a night tour.
Where to Bed: Bungalows at the Lapa Rios Ecolodge come with two showers (one alfresco) and huge private decks, where you can wake up to spectacular sunset views.
