July2012, We rented a jeep from ISAK 4x4 rentals. check out link. http://www.isak.is We explored Iceland from the Westfjords to the Eastfjords via the southcoast. We ventured into the highlands from Landmannalauger to Askja. We skied sand and snow then soaked in hotsprings. We explored glaciers and lava feilds while marveling at the waterfalls. Incredible.
