Affiliate disclosure

DiamondHeadTickets.com takes part in the Viator partner program. Booking links on this site carry our partner ID, and when you complete a booking after clicking one, we may earn a commission. You never pay more by booking through these links; the price is the same as going to Viator directly.

We earn nothing from Hawaii State Parks reservations, which you can book yourself for $5 per person. We are not paid by tour operators for placement, and the order of tours reflects what suits which hiker, not commission rates. We say plainly which tours include park entry, which leave you to hike alone and which never enter the crater.

Ratings and review counts are the figures Viator showed when the page was last built. Prices are from-prices in USD and move with season and availability; the checkout price is the one that counts.
