Like most of the High Tauern, the Hochalmspitze massif is formed of granite and gneiss, and many unusual rock formations can be found on its slopes. The mountain lies at the Eastern end of the range. In the northwest, a ridge connects it to Großer Ankogel, the third highest peak in its group, and to the Kölnbrein Dam. In the south, the Mallnitz Ridge leads to the neighbouring Reisseck Group.
