Known as one of Hawaii's premiere snorkeling spots, Hanauma Bay is very popular with residents and visitors alike because of its clear and calm waters.
Snorkeling is best early in the morning or later in the afternoon when the crowds are smaller.
Efforts to conserve the park's resources have resulted in reduced conjestion and a cleaner beach. The parking lot fills up rather quickly, so if you are not there early, you may not be able to get in until the early arrivals start leaving. The park can comfortably accommodate about 2,000 people at any one time. This number has never been reached, but if it does, your entry may be delayed until others leave. Parking on the streets outside of the park and walking to Hanauma Bay is discouraged, mainly because of the distance, a mile or more, and lack of sidewalks.
