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.
