About This Beach
Kehena Black Sand Beach is a unique and stunningly beautiful location on the Big Island of Hawaii, known for its black sand, powerful waves, and clothing-optional atmosphere. The beach is somewhat secluded, requiring a short but steep hike down to access it, and lacks basic amenities like restrooms. The strong currents and waves make swimming hazardous for inexperienced individuals, while experienced surfers and bodyboarders will find appealing wave conditions. A Sunday drum circle adds a distinctive, vibrant element to the beach’s atmosphere.
