World Amazing Stuff: Black sand beach in Hawaii

Black sand beach in Hawaii

Punalu'u Beach also known Black Sand Beach is the most famous black sand beach on the Big Island of the U.S state of Hawaii. The beach's black sand is made of basalt and created by lava flowing into the ocean which explodes as it reaches the ocean and cools.

Punalu'u is frequented by endangered Hawksbill and Green turtles, which can often be seen basking on the black sand. The swimming area is very rocky, and it’s dangerous to swim. The beach also has a large amount of underground fresh water that flows in it. This fresh water is very cold and looks almost like gasoline mixing with the water. Punalu'u Beach Park is located off Hwy 11 on Puna district's south shore, south of the town of Hilo.
