Makauwahi Cave, Archaeological cave site in Kauai County, United States.
The limestone cave formation spans 17 acres and contains a natural freshwater lake within a large collapsed chamber structure in Mahaulepu Valley.
Researchers discovered fossil remains of 45 extinct bird species in the sediment layers, including the turtle-jawed moa-nalo and Kauai mole duck.
Ancient Hawaiians used this location as a burial ground before scientists identified its paleontological importance in 1992 during a research expedition.
Visitors can access the cave through a two-mile hiking trail from Keoneloa Bay or via Grove Farm's private dirt road to join guided tours.
African sulcata tortoises maintain the surrounding grounds by controlling invasive plant species while supporting native flora restoration efforts.
