Dettifoss and Selfoss are two great waterfalls in a relatively short distance, with 0 effort required to explore them.
Dettifoss and Selfoss are two waterfalls located closely together, separated only by about one kilometer of easy walking along a cliff top.
From the parking lot it is easy to find the start the trail. Just to the right of bathroom, or the water closet (WC) is the beginning to get to both Dettifoss and Selfoss.
We started by walking to Dettifoss, following all the signs to the falls. It first kicks you out almost right on top of the falls. From there you can either walk down closer to the falls or further down stream from the falls to actually see the full cascade of Europe's largest waterfall in terms of volume of water. The trails closer to the falls will most likely be closed unless you are there in summer.
After Dettifoss, you follow the cliff upstream to find yourself at Selfoss. You will lose visuals of the falls the closer to the top of the falls you get.
The entire way is super flat with a few steps here and there. It is an easy walk to enjoy some cool water falls.
