1. Green Grotto Caves, located in Ocho Rios, Jamaica, is a popular tourist attraction known for its interesting geological formations and historical significance. The caves are made up of limestone and were formed over millions of years. They were used by the indigenous Arawak Indians as a dwelling place and were later used by smugglers to store contraband goods.

The Green Grotto Caves received their name from the lush green algae that covers the walls of some sections. The caves extend for over 1,500 meters (4,900 feet) and have a depth of 12 meters (40 feet) in some areas. The formations inside the caves include stalactites and stalagmites, as well as underground lakes and grottos.

Apart from its natural beauty, the caves have a rich history. They were used as a hiding place for Spanish refugees during the early colonization of Jamaica. The caves also played a role in the slave trade, as it is believed that escaped slaves sought shelter in the caves.
