This black beach was formed by the accumulation of volcanic ash, volcanic sand, and eroded volcanic rock that was washed down through the valley. The black color absorbs a lot of heat in the summer sun, enough to burn your feet. Every year sea turtles lay their eggs in the sand. Because of the sand’s heat it appears that the eggs develop faster than those laid further south.
