Kailua was a sleepy beach town until Obama blew up it's spot with his annual vacations while he was in office. He was born in Honolulu, but Kailua became his (like San Clemente became Nixon's) during his Presidency.
After visiting, I can certainly understand why he chose it, as the beaches in Kailua are -- hands down -- the most beautiful beaches I've ever seen in my entire life. And I've seen some beaches.
Usually after arriving on a beach, I take a minute to enjoy the scenery before:
a) jumping in the water
b) diving into a book or
c) falling asleep for a nap
....but after setting up on Kailua Beach I just sat there and looked around, in awe, for a solid 60-90 minutes. It's just astonishingly beautiful. These photos don't even do it justice, they're legit garbage compared to what it really looks like in real life.
Kailua Beach sits right next to Lanikai Beach. Both have the softest white sand and water so blue it brings the Leader of The Free World back every year.
