Bjarnarfoss is a 262 ft (80 m) waterfall located in the Snæfellsnes Peninsula of the Western Region. Bjarnarfoss is one of the tallest waterfalls in Iceland but receives little attention. What makes Bjarnarfoss a worthy waterfall to visit is its beautiful misty drop as it crashes onto the ground below. At the bottom of the waterfall is where the volcanic basalt columns line the cliffside. The columns look like man-made castle walls. This area, known as the Búðahraun lava fields, was formed by the now extinct Mælifell volcano. This is not to be confused with Maelifell in the Southern Region. The Western Region’s Mælifell is viewable from the waterfall and no longer active. The area and beautiful Bjarnarfoss are listed on the Nature Conservation Register.

In the municipality of Mosfellsbær, you can find the small waterfall Tungufoss. The waterfall is roughly 13 ft and is the lower part of the Köldukvísl river.
