The island of Oahu is a large island of the Hawaiian archipelago which is located in the northern part of the Pacific Ocean and is part of the state of Hawaii, USA. The warm climate of the island during the year attracts many tourists. The beach of Waikiki is considered one of the most picturesque beaches in the world, which is known among surfers. On the island, you can visit historical objects. Tourists like to climb the mountain of Mount Tantalus and admire the waterfalls. My friend sent me these warm marine photos. I'm happy to share with you the beauty of the sunny island of Oahu.
