The Experience

Before You Go

Book Pearl Harbor in advance

USS Arizona Memorial spots fill early—reserve tickets or arrive early for the film and ferry; tour operators often manage this but confirm beforehand.

Bring reef-safe sunscreen

Hanauma Bay is a marine preserve; use only reef-safe sunscreen and follow marine-protection rules to avoid harming coral.

Wear sturdy shoes for Diamond Head

The trail includes stairs and uneven pavement—light hiking shoes or sneakers with grip make the 560 ft climb more comfortable.

Carry a light daypack and water

Tropical sun and short hikes mean you’ll want at least 1L water, snacks, and a rain layer for sudden showers.

Local Knowledge

Hidden Gems

  • Pillbox trails on east Oahu for city-to-sea views without crowds
  • Makapuʻu Lookout for seabird sightings and offshore cliffs

Wildlife

  • Green sea turtles near rocky shores
  • Native seabirds like the wedge-tailed shearwater

Conservation Note

Hanauma Bay operates as a marine life conservation area with visitor limits and education programs; visitors are asked to use reef-safe products and avoid touching coral.

Honolulu was the political center of the Kingdom of Hawaii; Iolani Palace is the only royal palace on U.S. soil and Pearl Harbor marks the 1941 attack that drew the U.S. into WWII.

Common Questions

Are meals included in the tour?

Meals are generally not included—accommodations may include breakfast; guides will advise on recommended restaurants and breaks.

Do I need to reserve Pearl Harbor tickets separately?

The operator typically handles entrance but capacity-controlled elements like the USS Arizona ferry can sell out—confirm with your provider and consider booking official NPS tickets if you want guaranteed access.

Is the Diamond Head hike difficult?

Diamond Head is short but climbs about 560 ft over switchbacks and stair sections; it’s accessible to most people with moderate fitness and takes roughly 1–2 hours round trip.

Can I snorkel at Hanauma Bay on this tour?

Hanauma Bay requires reservations and a conservation briefing for snorkel access; some mini-tours only stop for viewpoints or photos—check if snorkeling time and entry are included before booking.
