Located in Selfoss, the ION Adventure Hotel is a remarkable modernist structure that sits on stilts, cutting an impressive outline in the already dramatic landscape. Once a spooky abandoned inn, it’s now a 45-room (choose between standard and deluxe) boutique hotel with outlooks over Nesjavellir Geothermal Power Plant or across the lava fields towards Thingvellir National Park. As with ION’s City Hotel, there’s a clear presence of salvaged materials in the design with the exterior mimicking the brutal conditions of Icelandic winter. Sigurlaug Sverrisdottir is behind the concept and manager to the ION brand. Once air cabin crew, she’d also created a business, arranging adventure tours -and there’s many wonderful excursions to be enjoyed from here. Adventure Hotel juts out on Mount Hengill as a secluded and sustainable retreat for those wishing to get off the beaten track.
