This is one of my absolute favourite day tours of Iceland. Þórsmörk is such a beautiful valley and it's always an adventure to get there. The best thing about it is that you get away from most of the crowds. This is because you need a super jeep to cross the rivers to get there.

It's an adventure in it's own only to ride in a super jeep while crossing deep rivers. You'll also go hiking, explore waterfalls and canyons.
