細岡展望台 / Hosooka Observatory

細岡展望台（位於紃路町）是位在紃路濕原東側的位置。在這裡可以遠眺紃路川的大型彎曲河道的樣子。在北側也可以看到雄阿寒岳·雌阿寒岳。這裡也以可以看到美麗的夕陽而著名。可以觀賞到川面所反射的夕陽和紅、橙、薄紫等顏色會變化的夕陽下的天空。一年之中都可以來展望台參觀，但是只有在夏季時才可以看到一片綠色的濕原。

Hosooka Observatory (Kushiro Town) is located on the eastern side of Kushiro Marsh. This observatory provides a panoramic view of the meandering course of the Kushiro River, or Kushirogawa in Japanese. Two big mountains, Me-Akandake and O-Akandake, can also been seen to the north. "Me" and "O" mean male and female. This place is famous for the sunset, with the sunlight reflecting on the river beautifully. The color of sky grows red, orange and pale purple, too. Access is free throughout the year, but if you want to see a green, leafy world, summer is the season to go.
