Enjoy the four-wheel-drive adventure of a lifetime on a tour that takes you through one extreme landscape to another in Reykjavik's vast hinterland. Head out early and drive to the Borgarfjordur area. Along the way, see Hraunfossar and Barnafosslava's lava waterfalls. Leave the paved road to encounter the gravel desert of Kaldidalur. After that, ride to the edge of Langjokull Glacier, and head out on the ice. Enjoy an hour on the frozen playground before re-energizing with lunch.
