Fjadrargljufur Canyon is yet another awe-inspiring reason why Iceland is considered one of the world's greatest playgrounds for adventure travelers. On your way from Vik (town) to Skaftafell (park) along the Ring Road south, keep your eyes open for the F 206 turnoff towards the towns of Laki and Holt. 15 km of sign-following and small, paved roads later, you'll arrive in the parking area for this spectacular canyon, which stretches for two kilometers into Iceland's interior along either side of the Fjaðrá River.
Depending on the weather and the height of the river (which tends to be surprisingly low), you'll have two options for hiking this beautiful landmass. Most visitors will opt for the traditional route along a paved path that steeply mounts the canyon and then follows along the ridge-line for its entire length. The views from the top are stellar, so don't let the fact that it's the more popular trail deter you. Provided you've got yourself a good pair of waterproof hiking boots, however, and aren't afraid to do a little cold-water wading from time to time, you can also opt for a trek up the river bed itself. While you might miss out on the bird's-eye view from above, there's something to be said for the sight of sheer palagonite cliffs towering 100 m above you as you hike seemingly through time. Whichever method you choose for exploring, just make sure you carve out a solid 2-4 hours to fully appreciate this beautiful scar of the Ice Age.
