Grænihryggur in Landmannalaugar hike

About the hike

The natural wonder of the cyan-green rhyolite ridge Grænihryggur, one of the pearls of Landmannalaugar is a spectacle that every fan of hiking in Iceland should see.

The hike to Grænihryggur is fun but challenging as you will walk up and down steep slopes and wade across glacial rivers along the way. The hike itself is around 15-18 km and takes about 8 hours so expect a long but rewarding day.  Note that there are 195 km between Reykjavík and Landmannalaugar, or about 3 hours by car.

You will walk in and up Halldórsgil ravine  and then walk down to Jökulgil. There you will cross the glacier river Jökulgilskvísl by foot a few times before you reach the spectacular Grænihryggur with it’s color that seems completely alien. The entire hike you will be surrounded by magnificent landscapes and endless colors in the rocks and fauna. This is without a doubt one of the most beautiful areas in Iceland, an untouched gem of a landscape. 

The Grænihryggur hike is an advanced hike. Be prepared for a long day and make sure your energy matches the challenge.

Why is it called Grænihryggur? The greenish turquoise color is caused by a bit of divalent iron in the glass of the rock in Grænagil and Grænihryggur.
