Búðir is encircled by the Búðahraun lava field where several trails begin. The easiest path is to Búðavík Bay where you can stroll among lava rocks scattered across Iceland’ largest, shell-sand beach. A few steps forward is Búðaós, originally called Hraunhöfn meaning Lava Harbour. This is an estuary of the Hraunhafnará River where merchant ships once docked. In the background is Mælifell, a rhyolite mountain with an elevation of 1,857 feet. Ambitious hikers may also want to explore the adjoining Búðahraun Nature Reserve.
