There are many reasons to stop by the exhibition beyond learning about sustainable energy and the power plant. Visitors can enjoy scenic landscapes during their visit with a cup of coffee and chat with our experienced staff, asking any questions they may have. Take a moment to relax in our Agndofa art installation, a multi-sensory experience introducing you to the natural landscape. There is a well-stocked souvenir shop filled with local products and Icelandic design. Refill your water bottle, charge your car, or stop by on your way to the many beautiful hiking trails in the Hengill area.

The exhibition at Hellisheiði Power Plant is ideally located in the Hengill area only a 20-minute drive from Reykjavik on your way to the South of Iceland. Drive along the main road heading towards Hveragerði, Selfoss, and the Golden Circle.
