Experience the natural landscapes of Oahu in all their glory on a four-hour outdoor adventure that leads you from a popular tropical garden, where you may enjoy shaded pathways surrounded by mature trees and tropical plantings in a peaceful setting, and to the hilltop Pu'u Ualaka'a viewpoint. The day begins with an air-conditioned ride to the Ko’olau mountain 1,050ft above Honolulu. Feast your eyes on sweeping island panoramas, which include the downtown Honolulu skyline, Waikiki Beach, the volcanic cone of Diamond Head, and Pearl Harbor in the distance. You will then drive through Punchbowl Crater, an extinct volcanic caldera that serves as the National Memorial Cemetery of the Pacific, honoring American heroes who are missing in action. The next stop is a naturalist-led walk-through a tropical garden, where you’ll spend time exploring its captivating natural beauty. On the return drive, you'll pass by ʻIolani Palace, the only royal palace in the United States and the former residence of Hawaii’s last reigning monarchs, a vibrant symbol of Hawaii’s proud cultural heritage and history.
