Coral Grotto

Coral Grotto lies along the coast of Kauai in the Hawaiian Islands, off the northern or western shoreline near the coordinates given, in the Pacific waters that surround the island. Dive sites in this stretch are typically reached by boat from harbors such as Port Allen or Hanalei depending on the season and swell direction. The site reaches a maximum depth of around 30.5 metres. Divers have reported angelfish, butterflyfish, wrasse, dolphins, and even hammerhead and whale sharks passing through, though these larger animals are occasional sightings rather than a guarantee on any given dive.
