Ok, day four, we decided to take it a little bit easy. (the truth is, we couldn't get up in time to catch a ride with Tommy and Patty, apparently we've missed out a lot of fun).

We hiked up in Diamond Head (Hawai'ian call it Le'Ahi) where it used to be part of the U.S. Army Coastal Artillery defense system. From the trailhead to the summit of the crater, it's about 0.8 miles and 560 feet from the crater floor. Quite an exercise.

We then hit the biggst flee market in the afternoon, I got some goodies in good deals. Headed back to the beach to catch the last boat ride to the ocean to see sun dawn, it was amazing:)
