Arashiyama is a district on the western outskirts of Kyoto. It is easy to reach from the Kyoto station with the JR Sagano Line (also known as JR Sanin Line), which goes to the Saga-Arashiyama station. If you are visiting Kyoto, you should take a day to go there. There are a lot of must-see places, including the famous Bamboo Forest, Togetsukyo Bridge and Monkey Park Iwatayama (my personal highlight). There are also beautiful temples like Tenryuji Temple or Daikakuji Temple.
