More ways to explore the area's outdoor wonders
You step off the coastal path and the bay opens beneath a rim of volcanic rock, the ocean flattening into a glassy, sheltered bowl where reef fish dart like coins in sunlight. Guides gather the small group at the entrance and, once inside, the water pulls you forward—warm, clear, and shallow enough to study the reef without deep diving.

History
Hanauma Bay formed in a volcanic cone; historically it was an important fishing ground for Native Hawaiians and is now managed as a state nature preserve and education center.
Conservation
The preserve limits daily visitors and enforces no-touch rules and reef-safe product recommendations to protect coral and the bay’s recovering ecosystems.

Pay the Preserve Fee in Advance
The $25 Hanauma Bay entrance fee must be paid to the operator before your tour day—watch for their text with payment instructions.
Bring Reef-Safe Sunscreen
Apply reef-safe sunscreen before entering the bay to protect coral and avoid reapplying in the water.
Be a Confident Swimmer
Non-swimmers are not allowed—ensure you’re comfortable snorkeling in open water and able to float or tread if needed.
Arrive Ready to Go
Meet your guide at the front of the entrance line; you won’t be allowed early beach access without your guide and timed ticket.
Mask & Snorkel (provided but bring own if preferred)
High-quality fit reduces fogging and improves visibility while snorkeling.
Reef-safe Sunscreen
Protects your skin and the bay’s coral—apply before arrival.
Rash Guard or Swim Shirt

Water Shoes or Sandals
Useful for walking the rocky paths and parking areas before reaching the beach.
