Punalu’u Black Sand Beach
Punaluʻu Beach (also called Punalu’u Black Sand Beach) is a beach between Pāhala and Nāʻālehu on the Big Island of Hawai’i. Punalu’u is one of the many beaches on Hawai’i Island that has black sand made of basalt. This black sand is created by lava flowing into the ocean which explodes as it reaches the ocean and immediately cools. This beach is frequented by endangered hawksbill turtles (honu ‘ea) and green sea turtles (honu), which can often be seen basking on the black sands of Punalu’u beach.
There are many fresh water springs in the shallow area and where the ocean meets the shoreline. You may occasionally feel a freezing cold vent of water from below, that is the underground fresh water seeping out into the ocean.
