12 km (7.45 miles)
Today you will start with another refreshing stream crossing as you make your way past the green volcano Storasula and into the black desert of Maelifellssandur. On your way, you will see Hattafell, a volcano with a strange flat top.
Before you reach Emstrur, take a detour just off the trail to see the amazing, 200m-deep Markarfljotsgljufur canyon. This canyon was carved out by the glacial river Markarfljót.
Your accommodation for the night will be at Botnar Hut - a little green oasis that will be welcomed after walking through the black desert.
