Do not follow the historical Toilet Bowl wave-entry instructions
The archive names Hanauma Bay's Toilet Bowl and includes dangerous jump, wave-suction and rock-exit instructions. Those are withdrawn from visitor directions. The historical education handbook records closure of the ledges leading there; no current authorization to use that route was established.
Hanauma Bay beach access is a different visit
Honolulu operates the managed preserve and lists lifeguards, bathrooms, showers and a tram to its beach. That does not authorize walking around rocky points to the Toilet Bowl. Ask staff about permitted boundaries and use the designated visitor route rather than an old pool-depth or wave-timing story.
Arrange tickets and parking independently
The current city page lists Monday and Tuesday closures. Nonresident adults pay $25 plus any online service fee; reservations are released two days ahead at 7 am HST, with limited walk-in tickets. Parking is not reserved by an admission booking and has separate cash charges. Confirm your visitor category and current operations.
Respect the bay rather than seeking a wave ride
Ocean conditions can change even at a staffed beach. Never use water surge as a means of entering or escaping a rock pool. The archive's Waikīkī jetty suggestion is not a current snorkeling route inspection. No separate Toilet Bowl facility or overnight permission is established.
