Glanni Waterfall is in the western region of Iceland right off the main Ring Road. It's the perfect place to get out and stretch your legs for a quick 15 minutes.

Starting at the parking area, walk towards the signs with hiking trail directions (to the right). From here you'll see a maintained gravel path heading to the right. Walk down this path for a couple hundred feet before turning left (you will see a viewing platform). From here you can retrace your steps back to the parking lot or explore the other little trails next to the river. 

Additionally, if you go during a salmon run or any other type of fish run up the river, there is a fish ladder and you can see the fish jumping from pool to pool to get around the waterfall!
