The king's palace and the French style Queen's summer house are situated on the top of the Blue Mountains (beautiful), and the view from Tanner Island behind is equally stunning. The place is small and the terrain is very steep but easy to reach. For locals, it is still a sacred place, especially the huge heart-shaped stone. I recommend buying a guide to explain all this. Also walk through the garden to the viewing platform at the top of the mountain. It’s about an hour or so from Tanner Island, and a half-day tour is great, or like us, spend a few hours here before the afternoon flight.
