The Gigalitz is a mountain, 3,001 m (AA), on the Floitenkamm ridge of the Zillertal Alps between the bottoms of Floitengrund and Stillupgrund.

From the Greizer Hut the path runs up to the col of Lapenscharte (crossing to the Kasseler Hut) to a signed fork at a height of about 2,500 m. It continues on an unmarked path to the unprominent southwestern arête and then on grassy schrofen to the two summits.

The journey time from the Greizer Hut is about 2.5 hours.

In July 2006 a summit cross was funded and erected by the "FND" (Freitag nach Dienst = "Friday After Work") pub regulars (Stammtischrunde).

One of several climbing tours, with 7 rope lengths and UIAA grade 4+/5-, is laid out on the neighbouring Gigalitzturm rock tower (2,978 m).
