The cliffs at Ketubjörg are interesting to visit. Just south of them a small stream falls off a cliff into the ocean, and a bit north there is another waterfall.

There is a nice waterfall in Selá, where it falls into the sea.

Close to the road there is a waterfall in Fossá. There’s another one just above the farm.

On a hillside in Laxárdalur valley there is a waterfall in the river Atlastaðaá. It can be seen from the road.

Also close to the road there are a couple of waterfalls in Grímsá, here and here. Upstream Hrafnsá falls into Grímsá, in a series of nice waterfalls.

Reykjafoss is a sizeable waterfall, in a somewhat dull environment. Easy to visit from the east side.
