From Arashiyama Station, cross the street and you will reach the bus stop "Arashiyama Tenryuji-mae". Take the bus 94 to "Otagidera mae". This is the highest point of the area of Arashiyama and our starting point. From here, we will take a walk through the historical streets of Arashiyama that are beautifully preserved and lined with amazing temples that are not overrun by tourists. You can do the itinerary in reverse, but it means you will have to walk uphill for 2,7km. Getting the bus up and walking down is the easiest way.
Make sure to check your connecting time in advance on Google Maps, as the bus 94 only runs once an hour. (which is also why I recommend to do the itinerary this way, a lot easier than arriving at the top and missing the last bus down.)
