Cheap flights to O'ahu from $250

Oahu, like all the Hawaiian Islands, has a laid-back vibe. So, in general, pack casual clothes. The exception to this is if you are flying to Hawaii specifically for a formal event. Swimwear is a must, so you can enjoy the iconic Hawaiian beaches. Pack lightweight, loose, breathable clothing and shoes that are comfortable for walking. Oahu is replete with gorgeous sites, and you're going to want to see so many of them. You should also bring sunglasses, a sun hat, and sunblock. And don't worry about whether it might rain or not. If it does rain on you in Oahu, the sun will be back out in no time to dry you off quickly.

If you want to absorb some Hawaiian history, you can visit Hawaii's Plantation Village, a recreation of a 1900’s sugar plantation. Iolani Palace is the one-time home of Hawaii's last monarchs. You can also visit the Pearl Harbor Aviation Museum. If you want to explore the great outdoors, you can enjoy parks across Oahu, but particularly clustered in the southwestern section of the island. You can also take a number of tours around the island, go on a dolphin watch, a turtle snorkel, or a shark cage dive. You can even arrange to swim with the dolphins or swim with the sharks. And if you want to feel like you're Magnum PI, you can indulge in a helicopter tour.
