One day is enough to visit both two sites, usually see the pandas in the morning, and then drive about two hours to Leshan city in the afternoon. Generally two hours are needed to see the Buddha and other historical sites on the mountain where the Giant Buddha locates. After visit, drive back to Chengdu. (Alert: Giant Panda Base and Leshan Giant Buddha are 150km from each other, approximately 2 hours’ driving. You need to leave from your hotel at around 07:00 AM so that you can visit both of them in a single day as the same time avoiding crowds as much as possible.
