In Romania, the Ciucaş Mountains are considered part of the Curvature Carpathians. Geologically, according to the divisions of the Carpathians, the range is part of the Moldavian-Muntenian Carpathians, of the larger group of the Outer Eastern Carpathians.
Iconic wildlife species live in the area of the Ciucas Mountains, from large carnivores species like bears, lynx, the wolves, wild cats, to the agile chamois and deer and various bird species like the Finch, the Nightingale, the Blackbird or the Golden Eagle.
What makes the relief so spectacular is its behaviour to the modelling agents. The process that generates the development of residual landforms like towers, cliffs, columns, mushrooms etc. is the detachment of rocks from their matrix under the action of moisture, and freeze-and-thaw cycle.
Tigăile Mari Summit is an unexpected association of towers, poles, needles, mushrooms, sugar loaves, polje etc.
Gropşoarele – Zăganu Ridge shows an alternation of deep and narrow saddles and sharp peaks.
Ciucaş – Bratocea Ridge is the highest elevation in the western part of the massif.
