It is very difficult to tell how it is beautiful to see coloured mountain with sea.
If you have a chance to visit Amanohashidate now, I recommend you to go up to the panoramic view point(500m above sea level).
Access: From Nariai-ji temple(成相寺) about 30mins walk(at least for me it took 30mins).
Five storied pagoda in Nariai-ji temple
P.S. I didn't retouch the pictures from what I really took ;)
