If you're coming to Oahu on vacation, you already undoubtedly know of some of the "must-do" activities - Pearl Harbor, the Polynesian Cultural Center, Diamond Head, a luau, maybe a sunset dinner cruise...

And all of these activities are great, and really shouldn't be missed.

However, as a resident living here, I thought I'd throw in my personal favorite things to do here on the island - things that aren't so well-known to every visitor.  And the best part is, most of these activities will set you back less than $10.

• Paddle an outrigger canoe in Kailua Bay

• Walk the trail to the Mokapu'u Lighthouse to watch the whales or canoe races

• Take the scenic drive along the east coast to the North Shore and eat tons of fresh fruit and shrimp along the way

• Hike to the top of Koko Crater and check out an amazing view of the island

• Spend a Saturday hanging out with friends at the Sandbar in Kaneohe

• Snorkel with turtles at Hanauma Bay

• Check out the art and sip martinis at "First Friday" every month on Nu'uanu Ave

• Wake up early for a breathtaking sunrise

• People watch in Waikiki

And of course, the list goes on and on...
