Panoramastrasse Oberaar is a very scenic paved high mountain road, with a length of 5,8km, climbing up to Oberaarsee, a reservoir in the Grimsel area, in the canton of Bern in Switzerland.
The road is narrow in parts with sheer drops and serpentine twists and turns. The road surface is fine but it is obviously a very slow road. It starts at Grimsel Pass. The access to this road is controlled by a traffic light. Travel is only permitted in one direction at these times: From Grimsel mountain pass to Oberaar xx.00 - xx.10 h. From Oberaar to Grimsel mountain pass xx.30 - xx.40 h.
It’s a fun ride if you enjoy narrow twisty roads high in the mountains. The Oberaar dam was completed in 1953. It is drained by the Oberaarbach, which flows into the Grimselsee. Check if the pass is open before going. Even if there is no snow, it can be closed due to the fog. The vehicles can have a maximum length of 10 meters. The Oberaar glacier is located west of the lake.

Starting from Grimsel, the ascent is 5.42 km long, through a narrow road 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 %. A challenging ride however hugely rewarding as the views from the top are spectacular. The road tops out at 2.401m (7,877ft) above the sea level.
