Daniel K. Inouye Airport (HNL), TheBus Route 20, and HOLO card

Daniel K. Inouye International Airport (HNL) sits 15 kilometres west of Waikiki (20 to 35 minutes by taxi, Uber/Lyft, or shared shuttle). Public transit riders can board TheBus Route 20 directly from the upper airport terminal level to Downtown Honolulu, Ala Moana Center, and Kuhio Avenue in Waikiki (note the luggage rule on TheBus: bags must fit under your seat or on your lap, roughly carry-on size).

Pick up a rechargeable HOLO card at any ABC Store or 7-Eleven in Waikiki for automatic daily ($7.50) and monthly fare capping across all Oahu buses and the western Skyline rail.

  • Use taxi/Uber from HNL if carrying large checked suitcases; use TheBus Route 20 if travelling with compact carry-on bags.
  • Buy a HOLO card at an ABC Store on Kuhio Avenue for $7.50 daily capped rides across the entire island on TheBus.
  • Rent a car only for the 1 or 2 days you drive the Windward Coast and North Shore to avoid $45-$60/night Waikiki hotel parking.

Choosing between Quiet Ends of Waikiki (Kapiolani/Diamond Head vs Ala Moana), Central Waikiki, and Kahala

Central Waikiki along Kalakaua and Kuhio Avenues puts surfboard rentals, Duke Kahanamoku Statue, and evening dining right outside your door. For a calmer stay within walking distance, pick the eastern Diamond Head end near Kapiolani Park and Sans Souci (Kaimana) Beach or the western end near Fort DeRussy and Ala Moana Beach Park.

East of Diamond Head, Kahala offers quiet luxury resort beaches away from the high-rise strip.

  • Diamond Head / Kapiolani Park end of Waikiki: quieter beaches, park greenery, and easy walking to the crater trailhead.
  • Central Waikiki (Kalakaua Ave): immediate step-out access to gentle longboard waves and sunset catamarans.
  • Ala Moana / Ward Village edge: calm reef lagoon at Magic Island and central bus hub at Ala Moana Center.

Two-day Diamond Head, Royal Downtown, and Windward Coast lookouts route

Day one hikes the paved switchbacks and tunnels inside Diamond Head State Monument on the first 06:00 or 07:00 reserved slot before heat builds, visits Iolani Palace (the only official royal residence in the United States) and the King Kamehameha Statue in Downtown Honolulu, hikes through bamboo forest to Manoa Falls or visits the Bishop Museum, and watches sunset from Magic Island Lagoon at Ala Moana Beach Park.

Day two circles the scenic southeast and Windward Coast: pass Halona Blowhole and Makapuʻu Point Lighthouse Trail, admire the sheer green fluted cliffs from the Nuʻuanu Pali Lookout and Hoʻomaluhia Botanical Garden in Kaneohe, visit the Byodo-In Temple at the Valley of the Temples, and swim at Kailua or Lanikai Beach.

  • Day 1: Diamond Head 06:00/07:00 reserved hike, Iolani Palace & Downtown, Manoa Falls or Bishop Museum, and Magic Island sunset.
  • Day 2: Southeast coastal road to Makapuʻu Lookout, Lanikai/Kailua, Hoʻomaluhia Botanical Garden, Byodo-In Temple, and Nuʻuanu Pali.
  • Pearl Harbor note: reserve USS Arizona Memorial boat tickets on Recreation.gov at 15:00 HST 8 weeks ahead (or the day before).

Mandatory park reservation windows, reef-safe sunscreen law, and surf safety

Oahu enjoys warm 26 °C to 30 °C trade-wind weather year-round; between November and March, huge Pacific winter swells hit the North Shore beaches (such as Banzai Pipeline and Waimea Bay, which become dangerous for casual swimmers), while south-facing Waikiki and Ala Moana remain gentle year-round.

Three Oahu icons require strict advance online reservations by non-residents: Diamond Head State Monument (opens 30 days ahead on gostateparks.hawaii.gov), Hanauma Bay Nature Preserve (opens at 07:00 HST two days ahead; closed Mondays and Tuesdays), and the USS Arizona Memorial at Pearl Harbor.

  • Book Diamond Head entry + parking slots up to 30 days ahead, and Hanauma Bay exactly 48 hours ahead at 07:00 HST.
  • Use only Hawaii-compliant reef-safe mineral sunscreen (zinc oxide or titanium dioxide; oxybenzone and octinoxate are banned by state law).
  • Never stop in the middle of the road for photos on the entrance drive of Hoʻomaluhia Botanical Garden; park in designated lots and walk.
