Geothermal Park Hveragerdi

The Geothermal Park (Hveragarðurinn) sits on the active geothermal field in the middle of Hveragerði, about an hour east of Reykjavík. Boardwalks lead past steaming vents, hot springs and bubbling mud. A small geyser erupts on its cycle; you can boil eggs in a spring, taste rye bread baked underground, and see a greenhouse growing tomatoes and even bananas. It is a compact, hands-on look at how Iceland lives on its geology — and a real hit with kids.
