Kewalo Pipe Dive
Urban Artificial Reef Transformed into Nature's Underwater Playground
Why Kewalo Pipe?
Located minutes from Honolulu's coast, this popular dive site showcases a unique coral-covered pipe structure surrounded by thriving reef formations. At beginner-friendly depths of 25-50 feet, divers discover an artificial reef teeming with Hawaiian marine life. The transformed underwater structure and adjacent coral gardens deliver exceptional opportunities for both macro photography and tropical fish encounters.
Diving Experience
This versatile site welcomes divers of all skill levels with its moderate depths and typically calm conditions. Most trips depart from Kewalo Basin, with morning dives offering optimal visibility. The coral-encrusted pipe creates a unique backdrop for exploration, while numerous hiding spots shelter diverse marine life. Both boat and shore access options are available, though boat diving is recommended.
Responsible Diving
Maintain distance from cave entrances and overhangs to protect delicate ecosystems. Follow current patterns to minimize energy use and reef impact. Remember that marine life always has right of way - practice patience and observation rather than pursuit. Local marine regulations require specific distances from protected species.
