There are many reasons to plan a Hawaiian vacation, and spending time in a perfectly comfortable climate under a palm tree on a sandy beach is one of them. But the islands are also home to many amazing natural sights (volcanoes, waterfalls, mountain peaks) and historical sights – nearly everyone who visits books a Pearl harbor tour. If you're a military history buff, few spots in the world have the significance of Pearl Harbor, and it is not to be missed. If you stay for a week or more, there will be time for a nice mix of relaxing activities and sightseeing to visit Hawaii's most scenic and historical spots.

Two places in Honolulu are fascinating to visit, and they are 'Iolani Palace which was home to Hawaii's last monarchs and used for many years as the state capitol building. The other is Kawaiaha'o Church, built of hand-cut coral slabs and completed in 1842. Both are unlike anything else in the world and are easy to visit if you're staying in Honolulu or anywhere in Oahu. The Diamond Head National Natural Landmark is a 200-000-year-old volcanic cone that provides outstanding views of Waikiki and Oahu's south shore. It's a defining feature of the Honolulu area and is something to visit with the whole family.

Natural history also abounds in Hawaii, and much of it has to do with volcanoes. The Hawai'i Volcanoes National Park is not to be missed for its splendor and uniqueness. You can also drive the Hana Highway in Maui for a scenic drive through a tropical rainforest – there aren't many places where you can have an experience like it. The east end of the route ends up in Haleakala National Park, where there's even more to do. If your kids enjoy photo-sharing platforms, they'll be snapping away during all parts of your historic site touring in Hawaii. There aren't many places where you can go and that you'll see as much.

Maritime history abounds in Hawaii since the state is a chain of islands. If you charter a private adventure boat tour, a local captain can take you to see more than Pearl Harbor. The islands have been a strategic military spot for many years, and during those times, each era has left its mark. While you're out on the water, you can look back at the land for panoramic views of mountain peaks and other scenic attractions. For both human and natural history points of interest, few places can match the variety and uniqueness of what you'll see in Hawaii. Make sure your vacation is well planned.
