Helgufoss is a charming waterfall nestled in the picturesque Mosfellsdalur valley, just a stone's throw away from Reykjavik.

The easy hike to reach it starts at Halldor Laxness' former home, adding a touch of literary history to your outdoor adventure. So, if you're looking for a tranquil escape from the city hustle, Helgufoss is the place to be!
