Mermaid Caves, Waianae

#7 of 9 in Parks in Waianae
Cave · Hidden Gem · Nature / Park
See if you can spot those fabled creatures of the sea at Mermaid Caves, still a kind of off-the-map hidden destination in Hawaii. The hike and the climb may be a bit difficult, especially for those with limited skills in adventure activities. The photos opps at the cave may be well worth the effort, but keep in mind that you'll have to conquer jagged lava rocks and descent through a hole into an underground cavern. Go there only during low tide and calm weather. Put Mermaid Caves into our Waianae trip builder website to see other points of interest to visit during your vacation in Waianae.

  • Amazing place! Small Xenote style water holes. Water is warm water was calm this was during the first weeks of October. If you are brave enough you can jump into some really cool caves. Crystal clear water with lots of sea life to see if you snorkel. I highly recommend having water shoes rocks can be rather sharp!
  • Amazing little gem, but when the tides are high I highly recommend not going in there. Amazing place for photos. The beach is not crowded like others and you get to go underneath and take awesome pics. Bring a ladder with you or rope if you can't climb in and out of there. I highly recommend to go only during daylight.
