3. Cocos Island, Costa Rica

Cocos Island is known as the legendary “Treasure Island” of the Pacific.
According to tales, pirates buried tons of gold and jewels here nearly 300 years ago. Many explorers vanished while searching for it, and strange sounds and lights are often reported in its forests. Today, the Costa Rican government has banned public access, preserving both its natural and mysterious allure.
