Distance: 7.5 km roundtrip. Elevation: 245m. Duration: 3 hours. Biggest waterfall in Iceland (196m). Tunnels and caves.
This amazing waterfall empties into a giant, beautiful canyon and with such a short hike, the reward is well worth the time. There are several caves to walk through and smaller waterfalls along the hike, which are all equally awesome to shoot. This is a great spot to hit up on your drive around the Western Peninsula or on your way back. It's also near the Golden Circle, a popular driving loop that hits several waterfalls and geisers that is definitely worth checking out.
To get to Glymur, drive northwest on Hwy 1 out of Reykjavik for 31 km then make a slight right onto Hwy 73. Drive another 30km and look for the parking lot on the side of the road. From the parking lot, follow the obvious trail away from the road. It is pretty straight forward all the way to the falls but keep track of signs, cairns, and yellow painted stones as there are some off shoot trails that will lead you astray.
