Luggage and bags:
I usually have a small back pack for holding my rain jacket, bottled water and some snacks.
Clothing/Shoes/Weather Gear: We did a lot of walking so comfortable shoes or walking boots are a must
Photo Equipment: We took lots of pictures so extra film or extra memory card is a good idea.
Clothing/Shoes/Weather Gear: The park is huge, and there is so much to see. Exploring the park and all the buildings in it, excluding the palace, will already take about 3 hours. Of course one could stay much longer. So bring comfy shoes that keep your feet happy during several hours on gravel walks.
