Vonarskard is an extensive highland area between Vatnajokull and Tungnafellsjokull, noted for its varied landscapes and geothermal activity. Colourful geological formations, hot ground, geothermal habitats and patches of vegetation occur within an otherwise stark highland environment. The area lies within Vatnajokull National Park and is valuable for both its geology and natural ecosystems. Vonarskard is remote and travel requires careful preparation. Visitors should protect fragile vegetation and geothermal areas by following routes and national park guidance.
