Day 3: The hike from Lake Alftavatn to Emstrur was probably one of my favorite part of the trip. We finally had a nice sunny weather and the lake was beautiful. It was nice to stop by for lunch at Hvanngil hut. The scenery was amazing with nearby mountains on the horizon. Finally, we hike on the famous lava fields as well at the black sand desert on our way to Emstrur.
