What should an active traveler do when it rains during their visit to Oahu, the third-largest Hawaiian island? Sun-kissed Oahu is among the most popular destinations in America for its beautiful beaches, stunning landscapes, and omnipresent volcanoes. Worry not, for Hawaii isn’t only about the great outdoors.
Though the island’s most iconic landmarks do require the weather to be on your side, there’s also a substantial selection of indoor attractions to enjoy. From royal residences to thriving underwater worlds and history museums galore, let’s take a look at the top things to do in Oahu when it rains, below.
America’s only royal residence
Good for: History, Photo, Unusual
Iolani Palace is the only official royal residence in the entire United States, which is a good reason to add it to your Oahu rainy-day itineraries. Even so, there’s more to this National Historic Landmark than the novelty factor. King Kalakaua had the grandiose structure built in 1882 to house the Hawaiian monarchs of the time, and the beautiful building is among Hawaii’s most majestic.
The palace features an American Florentine architectural style, with several sumptuous suites and extravagant halls. The State Dining Room, the Throne Room, and the Grand Hall are among the highlights. Check out the beautiful grand piano, which is made entirely out of the endemic koa wood. Read more

The Pearl Harbour Aviation Museum (Pacific Aviation Museum) is a must-visit for aircraft enthusiasts and history buffs in Oahu. And unlike the USS Arizona Memorial, which is the most popular Pearl Harbour attraction, this expansive exhibition space is entirely indoors and provides a much-needed respite from the rain.
The Ford Island museum has 2 separate 1930s-era seaplane hangars, both of which exhibit a wide range of vintage aircraft. Of particular interest is the Japanese A6M2 Zero, which crashed into the island of Ni’ihau during the Pearl Harbour attack. Tours of a B-17 bomber called Swamp Ghost that fought in the conflict are another major drawcard. Grab a self-guided audio tour to explore the site in your own time. Read more

Where to learn about the military history of Hawaii and beyond

The Hawaii Army Museum Society is a hit with military personnel or anyone interested in the history of warfare in the region. Also called the US Army Museum of Hawaii, this free museum occupies a 1911 coastal defense battery just north of Waikiki Bay.
Artifacts on display are from the early Hawaiian period right up until the Vietnam War. An AH-1 Cobra helicopter is the museum’s most impressive piece of hardware, though the artillery battery itself is well worth a look. Visit the Gallery of Heroes, which honors the country’s brave Medal of Honor recipients.
