Known as the "Gathering Place" for good reason, Oahu is a vibrant Pacific hub merging the urban pulse of Honolulu and Waikiki with the rural charm and surf culture of the epic North Shore. Oahu is the most populated of the Hawaiian islands, and is the main port and center of business and finance.

Begin the day with a hike at the Diamond Head , savor local delicacies at the KCC Farmers’ Market, or learn to catch a wave off Waikiki Beach, the legendary birthplace of surfing. Ocean activities thrive here, whether you’re into a SUP adventure or sunset dinner cruise with Waikiki’s shoreline painting the backdrop.

Located around the Waikiki excitement are Castle's vacation rentals. This iconic location features world-class dining where east meets west, and Hawaiian fusion come to life. Waikiki also serves as an excellent home base for guests who want to see world-class surfers on the North Shore, hike stunning trails, explore galleries like the Honolulu Museum of Art or visit historical sites like the Shangri-la Museum of Islamic Art or the only royal palace in the United States, Iolani Palace.
