The Volcano Museum, housed in the town’s old cinema, is the brainchild of vulcanologist Haraldur Sigurðsson, and features art depicting volcanoes, plus a small collection of interesting lava ('magma bombs'!) and artefacts from eruptions. A film screens upstairs. You can book a full-day geology tour (Ikr17,000) around the Snæfellsnes Peninsula with Haraldur.
