The Kleiner Solstein is a mountain, 2,637 m (AA) high, in the Nordkette in the Karwendel Alps in the Austrian state of Tyrol. Despite its name ("Small Solstein") it towers above its western neighbour, the Großer Solstein ("Great Solstein") (2,541 m (AA)) by almost 100 m (330 ft) and is thus the highest summit in the Nordkette. The southern side of the Kleiner Solstein facing the Inn valley is characterised by schrofen and steep-sided cirques. To the north it plummets in a rock face up to 600 m (2,000 ft) high towards the valley of Großkristental, which runs from the Gleirsch valley in a southwesterly direction to the Erl Saddle.
