“The Nutshell” is Mountain Taxi’s signature day trip special and a perennial favourite of our guests. A morning drive from Reykjavik in our Mountain Taxi Super jeep brings us to Kaldidalur or "Cold Valley". On our right lies the western side of the massive, nearly 1.000 square kilometer large Langjökull glacier, resting on a torn and twisted volcanic base. Depending on time of year, weather and conditions, your expert driver may use his super jeep's extreme abilities to climb the glacial slopes of Langjökull. An opportunity for cold, personal contact with nature's icy element. We drive from the glacier, through Húsafell to Hraunfossar waterfalls, dropping straight out of lava cliff faces into the glacial river Hvítá. From nature to culture, we visit the historic site of Reykholt, home of Iceland’s legendary chieftain and writer Snorri Sturluson. Here, he wrote some of the greatest Sagas of the Icelanders, brilliant literature also preserving the culture and history of the Viking Age to our day. See Iceland's oldest man-made structure, Snorri Sturlusons 13th century hot tub. Nearby is Deildartunguhver, the most productive hot spring in the Northern Hemisphere and a source of much of western Iceland’s heating needs. Our day wraps up in Reykjavik, taking in the scenic and historic Hvalfjörður fjord on the way.
