The Rheinwaldhorn (Italian: Adula) is the highest point in the Swiss canton of Ticino at 3,402 metres above sea level.

The peaks of the Adula form an irregular group, all the highest lying in a cluster not more five kilometres distant from the centre, which may be fixed as the foot of the Rheinwald Glacier.

The northern ridge, longer but less regular than the first-mentioned, extends fully 20 kilometres, from the central group to the Piz Nadils over Sumvitg in the valley of the Vorderrhein.

About 7 km west of the Rheinwaldhorn are the localities of Dangio and Torre (Ticino), at around 800 metres above sel level.

After overcoming the rocks, the travellers found the ridge wider, but also much steeper than below, and to reach the highest point it was necessary to wind round the north side of the peak, so that the final climb was made from the north-west.

In the following year Freshfield, with two friends, reached the summit of the Rheinwaldhorn from the side of the Lenta Glacier, striking the shoulder of the peak above the lowest point in the ridge connecting it with the Güferhorn.
