About This Beach
Kauapea Beach, also known as Secret Beach, is a secluded gem on Kauai's north shore, characterized by its expansive, golden sand, dramatic lava rock cliffs, and powerful waves. Accessing the beach requires a moderately challenging hike down a sometimes muddy trail, which contributes to its generally uncrowded atmosphere. While the rough surf makes swimming risky, the beach offers stunning views, opportunities for surfing, and a tranquil escape from the typical tourist crowds.
