Your four-hour excursion begins with a drive to the grand Iolani Palace. Completed in 1875, the palace is a National Historic Landmark and the only royal residence in the United States. After a self-guided tour of the State Apartments and Private Quarters, you'll travel to your next destination. En route, you'll pass the King Kamehameha Monument and the Kawaiahao Church, known as the "Westminster Abbey of the Pacific." Next, you'll make a photo stop at Mauna Ala, the final resting place of Hawaii's monarchs. Back on the road, you'll stop for Pali Lookout's breathtaking views. Then you'll tour the Hawaiian Mission Houses Historic Site and learn about the impact the missionaries had on the Hawaiian monarchy and people. At the conclusion of the tour, you'll reboard your vehicle and return to the pier.
