Guests can enjoy beautiful landscapes on their visit, grab a cup of coffee, and chat with our knowledgeable educators. Take a moment to relax in Agndofa, a multi-sensory experience space that stimulates the senses, inspired by the landscape of the Hengill area. Our souvenir shop has a good selection of local products and Icelandic design. Refill your water bottle, charge your car, or stop by along the way to explore diverse hiking trails in the Hengill area.
