The Hawaiian name for Kauaʻiʻs famous Secret Beach
Kauapea Beach earned the nickname Secret Beach because it is hidden from the road and requires a steep trail through vegetation to access. Once word got out, it was no longer very secret, but the name stuck. The Hawaiian name Kauapea is the original and proper name.
The beach sits below agricultural and undeveloped land. A small stream runs along the western edge, which can carry runoff after rain. The north shore of Kauaʻi receives substantial rainfall, so water quality can be affected during wet season. During dry periods, conditions are generally good.
The trailhead is off Kalihiwai Road near Kilauea. The trail is steep and can be muddy and slippery after rain. The beach has strong currents and no lifeguard. Waves can be large, especially in winter. It is also known as a clothing-optional area.
