The park was crowded, but the parking was well organized and as the area is huge the crowds weren't noticeable. Near the parking area are restrooms and souvenir/food vendors.

From here, and with the camera zoomed in, the climb doesn't look to bad. But it winds back and forth and toward the top it gets a little rough.

As with most high points around Oahu, this was the location of military defense installation. These, just north of the peak, were lookout posts.

Unusual plants are everywhere on the islands. These were along the trail. There probably not unusual to kama`aina (Hawaii Residents) but we've never seen thistles like these.

Besides the open trail, the climb to the top goes through a small tunnel and up this long steep flight of stairs. This was part of the military installation, as was the spiral stairway which is just beyond here. That takes you to a gun emplacement, where you squeeze through the gun slots onto a path to the stairway to the top. That's the one you saw in the second picture.

Finally, on the top. Jackie relaxes with Waikiki in the background.

Jackie moved to the side so we could show you this view of Waikiki Beach and most of the popular tourist area. It's breathtaking.

Like most points of land, Diamond Head needs a lighthouse. This one is right below the peak.

The view is great in all directions. This is toward the east with more beaches, mountains and points of land.

The trip to Maui on Sunday was on Go! Airlines, an inter-islandcommuter airline. The commuter terminal is small but has a shuttle bus to take passengers to the main terminal. Our flight was in a small jet, but some of these flight use airplanes with propellers.
