Öxarárfoss is a waterfall in Þingvellir National Park, Iceland. It flows from the river Öxará over the Almannagjá. The pool at the base of the waterfall is filled with rocks and is often extremely icy during winter. The river flows in the crack between two tectonic plates and the path to take you to the waterfall is at the base of this very crack. The walk to get here from the Visitor's Center is roughly 15 - 20 minutes. There are some steps on the way to the waterfall but overall, the path is easily walkable.
