The Fun Fun cave in the eastern part of the country is accessible for visitors to the Dominican Republic’s south and east coast resorts. Formerly known as La Cueva del Diablo, or Devil’s Cave, Fun Fun is said to be one of the largest in the world, and is certainly the Caribbean region’s longest cave. It has over seven kilometers of tunnels, underground rivers and spectacular rock formations, and is reached on horseback and on foot from Rancho Capote. Access to this cave is through a private property. There is little signage to get to the cave, so visitors need to secure a cave expert as a guide, or take one of the tours that are offered. This is not a cave that can be visited by oneself.
