Grundarfoss is a waterfall in the Northwest of Iceland, on the Snæfellsnes peninsula. The river Grundará falls over a cliff and ends 70 meters lower (in a single dropp) before it flows further to Grundarfjörður. The origin of the Grundará lies in the mountains where the melting water from the Rauðakúlur is responsible for the flow of the river. G
Grundarfoss is one of the highest waterfalls in the Northeast of Iceland and very impressive to see.
From road 1 you first have to go to Búðardalur (road 59), from there drive further on to Grundarfjörður (road 60>54). From the ringroad is a about 150 kilometer before reaching Grundarfoss. Grundarfoss is visible from road 54, but also a trail leads to the bottom of the waterfall.
There are several other (unknown and unnamed) waterfalls nearby. But Kvernafoss seems nice to me. It is situated a little bit west of Grundarfoss, just before Grundarfjörður.
