Helgufoss is a charming waterfall nestled in the picturesque Mosfellsdalur valley, just a short drive from Reykjavik. At twelve meters tall, it may not be the biggest waterfall in Iceland, but its serene beauty and mossy surroundings make it a perfect spot for a peaceful picnic. The area offers a glimpse of rural bliss with rolling fields, Icelandic horses, and old lava rock walls. It's an easy hike along the Laxness Trail to reach this hidden gem, making it a great day trip option for those looking to escape the city hustle and bustle.
