Limón Province, Costa Rica
Isla Uvita It's diminutive, to be sure, but “Little Grape Island” has a big claim to historical fame: Christopher Columbus landed here in 1502, anchoring his ships for repairs. Since then, a lot has happened (and been rumored to have happened) on this now-uninhabited island. It even once served as a quarantine site during a leprosy outbreak. Today, it's an easy and interesting day trip for beach lounging, surfing and hiking. Take a boat over to the quiet spot and play modern-day explorer, keeping an eye out for colorful bird and fish species.
