I went this Palace in a tour group. Due to time constraints, we were made to walk from the "Wu Men" (front) all the way to the back. One straight path passing all the main palaces. Do not forget to visit some of the palaces at sides. These are hidden treasures with less tourists and more intrigue. Certain smaller palaces even house artefacts etc. Also, do not forget to climb the hill "Jing Shan" (create from the earth excavated from the construction of the palace) at the back of the palace compounds. This will offer you a breathtaking view of the whole palace compound. Definitely worthwhile spending more time exploring the entire compound!!!
