Hike to Mermaid Caves, Oahu, Hawaii

Mermaid Cave, or tunnels as it's often called, has grown in popularity in recent times. But this is strictly for the adventurous few seeking to experience a hidden treasure in Hawaii. Mermaid Cave is located at Nanakuli Beach Park / Nanakuli Community Park / Kalaniana'ole Beach Park. To get there, you'll cross jagged lava rock that could cut up your feet, descend through an open hole (or puka) below into a breathtaking underwater cave.
