Upper Grindelwald Glacier, Valley glacier above Grindelwald, Bernese Alps, Switzerland.

The Upper Grindelwald Glacier (Oberer Grindelwaldgletscher) is a valley glacier on the northern flank of the Bernese Alps in the canton of Bern. It forms from a firn field bounded by the Schreckhorn to the south, the Berglistock to the east and the Wetterhorn to the north, then flows northwest as an ice stream 200 to 500 m wide through the deeply cut valley between the Mättenberg and the Wetterhorn. Its tongue lies at about 1,400 m above sea level and feeds the Schwarze Lütschine.

In its maximum extent during the Little Ice Age around the mid-19th century, the Upper Grindelwald Glacier reached down to 1180 m above sea level over a rock bar called the Nollen, ending opposite the Hotel Wetterhorn. Ice blocks were then cut from it for use in hotels and breweries. A narrow tongue reached the valley floor again in the advance of 1959–1985, and since 1991 the glacier has retreated rapidly.

In the 19th century the glacier reached the "Nollen" rock barrier and ended opposite the Hotel Wetterhorn, so it was easy to visit and often toured; ice blocks were cut out here for hotels and breweries. The Gleckstein Hut of the Swiss Alpine Club, at 2317 m on the southern slope of the Wetterhorn, looks over the glacier and the firn basin below the Schreckhorn.

The glacier tongue lies at about 1,400 m above sea level, one of the lowest ice fields in the Alps, and is reached on foot from Grindelwald; the Gleckstein Hut of the Swiss Alpine Club stands at 2,317 m on the southern slope of the Wetterhorn above the glacier, a high viewpoint over the ice and the firn basin below the Schreckhorn. Sturdy footwear is needed on the steep, wet or icy paths.

In the mid-19th century, when the glacier tongue reached about 1,180 m above sea level at the "Nollen" rock barrier, ice blocks were cut out of the glacier and sold to hotels and breweries. The Gleckstein Hut of the Swiss Alpine Club, at 2,317 m on the southern slope of the Wetterhorn, overlooks the glacier and the firn basin below the Schreckhorn.
