At this point, even I am tired of looking at Hawaii pics. I have this one last day that I just finished going through, and as it turns out, it was my favorite day for Oahu photography, so I'll share.
I started on southern West Oahu, and headed north. The further north I traveled, the more beautiful the beaches became. I especially loved the volcanic cliffs and black lava rock beaches, and the road became so beautiful as I reached Ka'ena Point with all the volanoes right along the road. I drove as far as the road took, which ended near Dillingham Airfield. These are the most beautiful sites I saw along the drive:
I liked this little sea wall. These walls are all over Oahu, and usually there are people fishing off them, or just hanging out. West Oahu was the most secluded coast by far, and even though it was just around noon, almost everywhere I went had no one around soaking up the immense beauty (which is what I like when I'm looking for prime photographic opportunities).

I believe this is Nanakuli Beach Park.

Further north, so probably Mali Beach Park (I wanted to get these posted before I forgot the names of all the places, but it took me a little too long. But, this is definitely in the area of central West Oahu):


This is near Waianae, and my favorite spot for photography:

Ka'ena Point. I was really excited to see this photo when I was going through the pics. I have to work on all my photos in Photoshop because I don't have pro-level equipment, and I have a pro-level eye. So I'm always disappointed. With a little work, I can get them to look great. I was so excited by this composition, that I worked hard on getting it right.

But then, I found this photo with the sailboat, which is nearly the same shot (without the sandy beach showing). Now I can't decide between the two -- they're like my children. Can't choose, so I'm posting both.

This was the last beach I photographed: Yokohama Beach. I was taking pics from afar, and noticed this interesting mini Stonehedge type thing going on... so I approached it. How nice of someone to leave this behind:

After reaching the literal end of the road, I turned back to go south, and stopped to get a photo of what the drive on that little road was like. Glad I took it, because I really like this shot.

Because I didn't really know the area and was discovering it as I went along, I wanted one shot for my last sunset that would be spectacular. If I was knew the island better, I would have stayed in Waianae or Yokohama Beach, but it was a few hours until sunset, and I was actually bored and ready to go home (I was flying out that night), so I wanted to start heading back to Honolulu. I figured I could get nearly all the way back in time for sunset, and then go to the airport. I had my eyes on Ewa Beach, which was still "West Oahu", but south, so a quick drive to the airport. Unfortunately, I couldn't have chosen a less inspiring Oahu beach. It was flat, there were no volcanoes to make exciting backdrops, it was so like any other beach ever, and I had no time to get to a better one. I arrived just a few minutes before sunset. There was literally nothing to be the subject of the photo except for this little fence from a beach house, and their trees. So, it would have to do. I was at least lucky to have spectacular colors and clouds to make the shot interesting:

And folks, that's it. It took 22 hours to get back home, which was awful. I will probably never go out to Hawaii again, but if I do, I'd love to go to the big island and see the active volcano.
So, for anyone visiting Oahu, my best recommendations:
Chief's Luau (located inside Sea World). I went to that one because it was the top rated, and yes... I can't imagine a better one. I paid for front table seating, which was nearly double, because I knew I'd want photos. But, if you're not there for photos, you can get by with a regular table. My tour guide made a point of letting me know that this luau is one of the smallest, with "only" 500 people, whereas others have many times that amount. So, every seat was wonderful. If you pay more, you get extra drink tickets, the same food, closer seating, and a different quality of lay.
A doors-off (doorless) helicopter tour.
Do NOT leave Hawaii without snorkeling at Hanauma Bay
If you're there during active whale season (February - April), do a whale watching cruise
Get out of Waikiki unless you're really into crowds or want to rent a jet ski
Without doubt, get in a car and drive along the West Oahu coast.
Good luck, SK. We're looking forward to hearing from you about your trip, and seeing some of your pics.
