2Kilauea Beach, Hawaii, USA

The island of Hawaii is home to Kilauea Beach, which lies near one of the world’s most active volcanoes, Kilauea.

The combination of volcanic activity and dangerous waters makes this one of the most perilous beaches in the world. Lava from Kilauea has been flowing into the ocean for decades, creating hazardous conditions like acidic steam clouds and sharp volcanic rocks. 

The area is also prone to unexpected tsunamis and earthquakes, adding to the danger. While the volcanic landscapes are breathtaking, swimming at Kilauea Beach is a serious health risk.
