Oahu's big waves and warm waters are a magnet to all types and sizes of mammals, finds Paul Davies.
It's difficult to avoid the island of Oahu when you visit Hawaii. Being the home of Honolulu and its international airport, you have to at least stretch your legs before transiting to your final destination - often Maui or another less populated island in the Hawaiian chain. However sometimes when people want to get away they go too far, spending too much time and money trying to get further and further away from the stresses of everyday life. With Oahu, you've got it all - that Pacific getaway vibe with all the trappings of a modern American city.
From the descent into Honolulu airport you can see just how coveted this volcanic island is. Huge US Airforce airplanes line up at Hickham Airfield, right next to the hallowed waters of Pearl Harbour. A visit to the memorial site of that fateful day in December 1941 helps you understand Hawaii's geographical importance as a gateway between east and west. Curiously guided by Jamie Lee Curtis on an audio tour, I could see the context of the attack laid bare - detailed descriptions of 1930s geopolitics live alongside displays telling of the persecution of Hawaiians of Japanese ancestry. Large groups of Japanese tourists meander through Uncle Sam's mea culpa of sorts, with the story explained by an enthusiastic translator. A short boat ride away is the Arizona Memorial - a haunting tribute that floats above the resting place of more than 1000 sailors killed aboard the sunken battleship, USS Arizona. Out of respect, the ship has been left completely "as is", in an almost "tapu" situation that silenced even the most boisterous tourist. Droplets of fuel trapped in the tanks swam to the surface to create tiny oil slicks - said to be the tears of the fallen. A tour of the USS Bowfin lifted the at-times sombre experience. After being ushered aside on the World War II submarine to make way for a 97-year-old veteran who had worked on the air conditioning of that very vessel, I was invited to join his official tour. Joe Corsiglia recounted with clarity the gravel on the road erupting in front of him as the machine-gun fire from a Japanese fighter approached. He instinctively dove into a nearby ditch and lived to tell the tale more than 70 years later.
Not quite as bloody but just as significant, the Iolani Palace in downtown Honolulu is the only royal palace in the United States. It was the residence of the Queen before Hawaii was annexed in 1898. The nearby market has fresh food and crafts and it is worth checking out one of America's oldest Chinatowns on the same stroll.
