If you are short on time the best way to prepare for the South Shore or the Golden Circle is to stop for the movie that shows the latest eruptions in Iceland, including the Eyjafjallajökull eruption that stopped air traffic in Europe in 2010. The movie is tailor-made for the exhibition. Many of Iceland's best mountain guides use the movie as an introduction to what lies ahead. It can be hard to imagine the massive forces of these huge eruptions when the volcanoes are quiet and the sun is shining. The movie runs three times an hour so you can stop by any time during the day. In the entrance area, there is also a lot to see, earthquake monitors and stories from people living close to active volcanoes. Grab a coffee and snacks, buy some souvenirs or simply connect to the WiFi and use the lavatories while you're here.
