Mt Hvitserkur is one of the most peculiar mountains of the country. Its main structure is light coloured rhyolite lined with basaltic dykes brought to the surface by the glacier erosion during the ice age. It hides its interesting sides when looked at from Borgarfiord. People either walk up to it or use their 4wd vehicles to get closer to admire this wonder of nature. No one, who makes that effort, regrets it.
