If you are visiting Amanohashidate from Kyoto or Osaka as a day trip,
PLEASE make sure you going to arrive at Amanohashidate in the morning or at latest noon. Especially if you are plan to walk though Amanohashidate itself (pine tree forest).
And I don't recommend you to try visiting Amanohashidate&Ine by a day trip from Kyoto or Osaka, that is tooooooooo rush. Due to sunset is earlier and closing time of everything is earlier in winter.
