The valley Glerárdalur is a long and uninhabited valley southwest of Akureyri. A nice 11 km walk leads from the mouth of the valley to the bottom of it and ends by the mountain cabin named Lambi. The path starts at the same parking lot as the hike to Mt. Súlur, but instead of going up and south following the yellow poles, you must continue straight into the valley along some tracks. It is a soft elevation hike, good for all ages, with a clear path that is easy to follow. Walking it to the end of the trail can be more challenging, as the whole hike is 22 km long (round trip).

The valley is surrounded by the highest mountains in the north of Iceland, the highest being Mt. Kerling (1,538 m), Mt. Tröllafjall and the glacier Vindheimajökull from 1,100 to 1,400 m high. This is a magnificent outdoor area both in summer and winter.
