Eldborg, a nicely shaped crater about 30 min. walk from the highway, ca. 100 m above sea–level, from which the big Eldborgarhraun (Eldborg lava) flowed. Eldborg is believed to have erupted once many thousand years ago and again in settlement times, as mentioned in Land­náma­bók (“The Book of Settlements”). It is a protected natural feature.
