Siloette of Keilir
Taken from a rib whilst whale hunting this volcanoe leaves a distinctive shape on an evening skyline. Mount Keilir is a small volcanic mountain to the south west of Hafnarfjörður. It can be easily visited when travelling between Reykjavík and Keflavík Airport, or the Blue Lagoon.
The mountain was formed during the Ice Age, underneath a glacier and is classed as a hyaloclastite mountain, although scientists believe it to actually be the plug of a large crater. Hikers enjoy climbing the mountain as it's not too high, but still poses enough of a challenge. Once you climb to the top, which takes around 2-3 hours, you are rewarded with a beautiful 360-degree view that simply takes your breath away.
