In the northern Kyoto region, Mt. Oe, Fukuchiyama City, is famous for its unkai, or “Sea of Clouds”. Mt. Oe is out of the way and it may be difficult to see the Sea of Clouds there. However, in Maizuru City you can also see the Sea of Clouds from Gorogatake. It truly is an awesome experience if you have never seen anything like it before. The Sea of Clouds really looks like the ocean. You will need a car or you can walk along the road to the top. The best viewing times are just after sunrise in Autumn or late winter.
Living in northern Kyoto prefecture with my wife and baby. I love to get out and find the small hidden places.
