1.2-mile hike along a boardwalk past steaming volcanic vents, fumaroles, mud pots and boiling hot springs and then climbing through the steam along a lava field to the 400-foot-summit of a hill overlooking the entire geothermal area. The view from the top was definitely worth the climb. The hills were painted in earthy hues of golden brown, red, yellow, white, and gray, with Lake Kleifarvatn in the distance.
