It is a noted location to see the wallcreeper, an uncommon cliff-dwelling bird.
The road along the 8 kilometres of ravines, often in serpentines with rock on one side and a sheer drop on the other, is one of the most spectacular drives in the country. Also within the Chei (gorge/canyon?) is Lacul Roşu (the Red Lake), with its traditional cabins, hotels, and its famous lake (situated at 980m altitude) caused by a landslide in the 19th century.
Cheile Bicazului is one of the main rock climbing sites in Romania.
