Oahu is arguably the most well-known of all the Hawaiian Islands. The name "Oahu" translates to "The Gathering Place" in Hawaiian. it is irregularly shaped, with mountains on its northeast and southwest sides and a large natural harbor (Pearl Harbor) facing the south. The town of Honolulu, which is the state's capital and the island's major city, is situated here. If you have ever been there you will know that the vibe is very laid-back.
