Hanauma Bay Nature Preserve

Famed for its beautiful horseshoe-shaped sandy beach and clear, calm turquoise waters, this natural marine sanctuary is home to thousands of colorful tropical fish. The waist-deep water inside the reef is perfect for novice snorkelers to explore. More experienced snorkelers might want to check with the lifeguard before venturing beyond to deeper waters to see sea turtles and other marine life. The Bay is least crowded in the early morning or late afternoon.
