Summary adapted from the Wikipedia article (CC BY-SA 4.0).
Aldeyjarfoss is number 10 on our list of waterfalls at the ends of the earth. As a cascade waterfall, water tumbles down a series of rock steps rather than falling free.
No commercial adventures run at Aldeyjarfoss itself — the experience is the approach and the view. Guided day trips from Northeastern Region are the easiest way to combine it with the area around it.

Snowmelt feeds the falls from late May; June to August is the short, bright season, and many access roads close in winter.
