Relaxation and surfing are two things that come to mind when Waikiki neighborhood and its beach are mentioned. You don't have to be a surfer to go- it's just as much fun to watch. Let the sun-colored sand cushion your feet and watch those perfect surfing waves roll onto the beach. When you're ready for more than the surf and sand, head to Kalakaua Avenue which lies parallel behind the beach for great shopping and dining.
Pearl Harbor and the USS Arizona are the most visited United States WWII memorials for a reason- everyone leaves feeling the experience was worth every minute. There is a shuttle that can take visitors from the USS Arizona to the USS Missouri, another battle ship, which is now a memorial. Don't forget to go to the Aviation Museum and the USS Bowfin Submarine Museum either!
Grab your water shoes and some insect repellent and that's about all you'll need besides your swimming suit and camera if you're going to Manoa Falls. This 100-foot waterfall is a great example of the ecological diversity and beauty of Hawai'i's islands. The trail is easy for any kind of hiker to master, and the rainforests surrounding it will take you to a different world. You'll soon understand why Steven Spielberg filmed Jurassic Park here. The falls are open from sunrise to sunset so you're able to admire the scenery at the falls any time of day!
This isn't the place for your amateur surfer, as the waves here are simply too intense for anyone that isn't close to professional, but it makes it the best beach for those looking to catch some sun as surfing spectators. Because the waves can be so big here, there are always lifeguards on duty for your safety if you're looking to swim (summertime waves are perfect for swimmers!). Sunset beach, as the name suggests, is also a wonderful place to enjoy the sunset and it's not as crowded or touristy as other sunset-viewing areas.
This cemetery sits on a majority of the crater here and memorializes all the veterans who served and/or gave their lives for their country. There are some notables buried here, including Ernie Pyle and Stanley Dunham. This memorial has moving tributes as well, such as the Honolulu Memorial which commemorates those who fought in the Vietnam War, Korean War, and in the Pacific during WWII.
