Tumbling in a broad sweep over a 100m-rocky scarp at the head of Dynjandivogur bay, Dynjandi (Fjallfoss) is the most dramatic waterfall in the Westfjords. The bumpy drive to Dynjandi, from either direction, is famous in Iceland for its incredible views; you'll see how the falls are the catchment area for peaks and inland valleys all around.
In 2015 there is slated to be a bus between Ísafjörður and Brjánslækur, summer only, that should stop at Dynjandi. Check www.westfjords.is for the latest information.
Climbing up from the car park you’ll pass many smaller falls until you reach the thundering main chute. You're allowed to approach the massive cascade as it plunges over the mountainside, and views over the broad fjord are spectacular.
The surrounding area is a protected nature reserve, but there’s a free (albeit noisy) campground at the falls, with pit toilets and running water.
