Fjaðrárgljúfur Canyon is a magical and maybe the most beautiful green canyon in Iceland. It is about 100m deep and 2km long. The canyon might be some 2 million years old and was formed by a forceful glacial river. Now the small Fjaðrá river runs like a snake between the steep walls of the canyon. Most of the ledges are fenced off and there’s a view platform by the waterfall because nature was too damaged because of the amount of visitors.

We heard that you can also walk inside the canyon (only in summer time) because the water levels of the river are usually not high. You might still need to wade the river a few times. We didn’t know about this while we were there, but we’re sure it’s definitely worth seeing the canyon from this point of view as well.
