Not a tour as such but if you're looking to see the temples I'd recommend starting from Kyoto Station; there's a 500 yen all-day bus ticket and the staff at the tourist desk are extremely helpful. If you've only got half a day I would recommend trying for either the temples to the north (Kinkakuji for e.g.) or south (Inari-yama) as it might be hard to fit them all in. I covered all of the temples in 2 days using the local buses and found it quite easy to navigate, even if you can't speak any Japanese.
Hope that helps! 9 months ago
