Panoramastrasse Oberaar is an asphalted high mountain road, with a length of 5,8km, climbing up to Oberaarsee, a reservoir in the Grimsel area, part of the municipality of Guttannen, Switzerland at an elevation of 2.303m above the sea level.
The road is extremely narrow with sheer drops and serpentine twists and turns. The Oberaar glacier is located west of the lake. Its surface area is 1.47 km². The Oberaar dam was completed in 1953. It is drained by the Oberaarbach, which flows into the Grimselsee. Starting from Grimsel, the ascent is 5.42 km long, through a narrow road leaving the summit, climbing further into the mountains giving closer views of the nearby glaciers. Over this distance, the elevation gain is 185 meters, and the average percentage is 3.4 %. The access to this road is controlled by a traffic light. It’s very exciting and sometimes very exposed and unsecured driveway in innumerable twists and turns. This infamous road is tightly hairpinned and bumped, an exquisite winding mountain drive with sharp and blind curves and hairpin switchbacks leading the traveler over the mountains.
