As the old Embark.org adage goes, "You don't get to be named after the Norse god of thunder unless you've got something pretty impressive going on." Look, we don't get paid extra to write adages, okay? The point is, there's a reason Thorsmork (or, more correctly, Þórsmörk) has become one of the most popular outdoor destinations in a country renowned for its natural splendor. Whether its the (comparatively) warm microclimate, the lush vegetation, the magnificent valley, the precipice-lined canyons, the accessible outlet glaciers, or the nearby volcanoes, this place has got a little bit of everything an adventurer could ask for, all tucked away in a setting that would make even Tolkien a little whimsical.
For starters, Þórsmörk is the connecting point between two of Iceland's greatest treks: Laugavegur (55 km) and Fimmvörðuháls (25 km). Thus, if you're looking for a multiple-day hike, this is a great spot to either start your end your journey. Should you prefer your adventures a bit more bite sized, there are tons of single-day trails around (including the popular Stakkholtsgjá canyon/waterfall trek), as well as some of the best mountain biking terrain you'll find in the country. You can also book tours of surrounding glaciers like Eyjafjallajökull, site of the relatively small but disruptive eruption in 2010. With so much to do, you'll likely want to give yourself a couple days here to check out just why this little slice of Iceland lives up to its namesake.
