American collector and philanthropist Doris Duke, when travelling through North Africa, the Middle East, and South Asia, gathered an amazing collection of Islamic art. Her mansion Shangri La became the centre of Islamic art and culture, and Oahu became the second home for her. There are more than 3,500 exhibits in the collection, and the guides will tell about the unique life of this rich American lady that founded the Islamic Art Foundation in Hawaii.

Getting to The Kaniakapupu Ruins (the ruins of the summer home of King Kamehameha III) is not so easy. To do this, you will have to overcome a dense bamboo forest. There are no usual hiking trails, there is only a small tunnel into the forest, which is quite difficult to find. This is one of the most impressive ancient structures on the island of Oahu, hidden in the local forests.
