Rock Quarry Beach, also known as Kahili Beach, is a charming and often secluded beach situated on Kauai's North Shore near Kilauea, Hawaii. This beach is uniquely positioned where the Kilauea River meets the ocean, creating a natural river mouth alongside a large sandbar, which forms a calm pool ideal for swimming and fishing. The beach is backed by lush woods with no visible homes, giving it a tranquil and unspoiled feel that appeals to visitors seeking a quiet retreat away from busier shores.
The beach is notable for its large calm swimming area, making it a family-friendly spot, while the proximity of the former rock quarry adds an element of rustic exploration. On days when the surf picks up, Rock Quarry Beach becomes a favored location for surfing and bodyboarding, drawing energetic beachgoers. However, visitors are advised to be cautious during murky water conditions due to occasional sharks and rip tides. The beach's laid-back atmosphere and natural beauty make it a hidden gem for those exploring Kauai's coastal offerings.
Anglers often fish at the river mouth, and the adjacent calm waters are perfect for snorkeling on the opposite side of the pool. Kayak enthusiasts can launch from the nearby parking area and enjoy a peaceful paddle up the Kilauea Stream, providing a gentle outdoor adventure that complements the beach experience.
