Warm Pond at Ahalanui Park

Ahalanui Park Warm Pond is a natural volcanically-heated pool located over Kilauea's east rift zone on the Kapoho Coast. Separated from the ocean by a seawall, the pool measures approximately 50x20 yards and is between 3' and 6' deep depending on the ocean tides.

The pond is fed by thermal freshwater springs - fresh rainwater washed through the porous lava rock, heated by the magma below, mixes with seawater to create a very large hot-tub. The ocean enters the pond through a narrow channel to create a delightful mixture of cool salt water and warm fresh water.

The salt & pepper sand found at Ahalanui pond is a mixture of white sand made from coral and black volcanic sand mixed with shell fragments from the sea.
