Aloha Stadium Swap Meet and Marketplace (outdoor market, $1/pp)

Aloha Tower (go to the top of the tower for some awesome views of Honolulu)

Diamond Head (hike up the crater (.8 miles) and overlook the awesome views of Waikiki)

Drive around the island to the North Shore (famous beaches, visit Haleiwa)

Halona Blowhole (natural lava tube blows water into the air, stop to see it on your way around the island)

Hilo Hattie (lots of Hawaiian souvenirs, go to see the worlds biggest Hawaiian shirt, they even have shuttle from Waikiki)

Ka’alawai Beach (hidden beach in Kahala, no facilities or parking, a bit rocky, great for snorkeling, tons of fish in the eastern end)

Ka’ena Point (as far west as you can get on the island, can get there from the North shore or the Wai’anae Coast (southeast-great hike), 3ish miles, look out for whales and turtles, once you get into the fenced in reserve watch the albatross and maybe some monk seals)

Kapiolani Park (great park to run/bike through, lots of events, Zoo and Aquarium are here too)

Lanikai Beach (great hidden beach in Kailua, no facilities or parking, nice snorkeling-not too many fish but tons of coral)

Luau (we did Paradise Cove- it’s the one of the best ones and it’s in a nice area, the other luaus are near buildings and aren’t as authentic, it’s a little cheesy but fun, you have to do one-it’s Hawaii)

Makapu‘u Point trail hike (parking, amazing paved hike, great views of the lighthouse and whales (if its whale season), check out the 7 blow holes- ‘Dragons Nostrils’ along the path)

Shark Dive (North Shore Shark Adventure takes you out in the middle of the ocean (about 3 miles from shore) and you go into a cage while sharks swim around…it’s pretty cool, a little freaky though)
