An Overview of Oʻahu

Oʻahu is the most developed island in the chain, home to Honolulu and about two-thirds of the state’s population. It is also the most diverse: city streets, famous surf breaks, farm fields, and quiet windward beaches, all on one island. Our sister site loveoahu.org covers it in depth.

8/9: Questions & Answers

Frequently asked questions about visiting Oʻahu (5)

Q: How many days should I spend on Oʻahu?

We recommend at least 4 days on Oʻahu, and more if you can. It is the most developed island, so it packs a lot in, from Waikīkī and Pearl Harbor to the North Shore and the windward beaches.

Q: Is Oʻahu too busy or touristy?

Oʻahu is the most developed island and Waikīkī is genuinely crowded, but the island is also the most diverse. Head to the windward coast, the North Shore, or the leeward side and you will find quieter, more local corners.

Q: Do I need a car on Oʻahu?

You can get by in Waikīkī and Honolulu with TheBus, rideshare, and walking, but a rental car makes the North Shore, windward coast, and leeward side far easier to explore.

Q: What are the must-do activities on Oʻahu?

For a first visit we would prioritize Pearl Harbor, Diamond Head, snorkeling at Hanauma Bay, a day on the North Shore, and the beaches around Kailua and Lanikai.

Q: When is the best time to visit Oʻahu?

Oʻahu is good year-round. Summer brings calm North Shore water for snorkeling; winter brings the famous big surf. Spring and fall tend to be the best balance of weather, crowds, and prices.

9/9: Free monthly newsletter

The only spam we like comes from a can.

Seriously though, one of the ways we stay as up-to-date as we can on all things Hawai’i as we can is by reading many Hawaiʻi newsletters. Letʻs say we were not happy by how many of those are mostly written to sell, not to inform.

We decided to do better.

Our newsletter is written to add value to your inbox.

Created for those people wanting to keep up with what’s happening on the Hawaiian islands and published once a month, here is what you can expect:

  • Upcoming local events
  • New and noteworthy places and restaurants and other venues
  • Our take on current affairs (what about those hotel prices!)
  • Volcano updates
  • Upcoming astronomy events (think about meteor showers and lunar eclipses)
