Is snorkeling in Hanauma Bay worth it?

Yes — Hanauma Bay is worth it for most visitors, especially first-time snorkelers and families. The protected volcanic crater creates calm, clear water with fish so accustomed to humans they swim right up to you. Entry costs 5 per person and advance reservations are required — slots fill days to weeks ahead at hanauma-bay.org. A mandatory 10-minute educational video plays before entry. The bay has restrooms, a snack bar, and gear rentals on site. Arrive when it opens at 6:45 AM to beat crowds and get the clearest water. The main criticism is that the reef has thinned over decades of use, but fish density remains excellent. For snorkelers who want more dramatic underwater terrain, Sharks Cove is the alternative. Hawaii Nautical snorkel cruises (0–150) offer guided alternatives if reservations aren't available.
