These beaches serve different purposes. Go to Hanauma Bay for snorkeling. Go to Kailua for beach activities and a more local vibe. If possible, do both on different days.
Sandy beach, minimal reef. Not a snorkeling destination.
Marine sanctuary, coral reef, 400+ fish species. Hawaii's #1 snorkel spot.
2.5 miles of white sand, calm water, open ocean feel. Outstanding.
Good swimming in the bay, but rocky entry in some areas. Fine for most visitors.
Generally good, but more affected by rain runoff (Kawainui Canal).
Protected sanctuary, excellent quality, minimal runoff risk. Both good — tie.
Free, no reservations, open daily, easy parking. Take the bus or drive.
$25/person fee, advance reservations required, closed Tuesdays, limited parking.
Charming Kailua town, local coffee shops, kayak rentals, windward O'ahu feel.
Touristy but managed well. Educational marine center. Required briefing video.
Hanauma Bay reservations sell out weeks ahead. The bay is closed Tuesdays. Book at honolulu.gov before you arrive in Hawaii. Entry fee: $25/person (free for Hawaii residents and children under 13). Without a reservation, you cannot enter.
