Kozí chrbát, Mountain summit in Starohorské Hills, Slovakia.

Kozí chrbát is the highest summit of the Starohorské Hills, reaching 1,330.4 m on the main ridge above Moštenica near Banská Bystrica. Its largely grassy top and partly wooded slopes lie on the border of the Banská Bystrica and Ružomberok districts. The summit rocks are limestone over crystalline bedrock, and the northern slopes fall into the Barboriná valley.

Kozí chrbát is the highest summit of the Starohorské Hills, a range only recently separated from the Low Tatras as a distinct geomorphological unit; older descriptions still list it within the Low Tatras. Its summit parts are built of limestone rocks overlying crystalline rock, which supports rich vegetation. The northern slopes above the Barboriná valley were declared the Kozí chrbát nature reserve.

The name Kozí chrbát means "Goat's Back", after the grassy ridge that runs from the summit west toward Kečka. The summit's former pastoral halas are still open grassland, and the ridge is crossed by the red-marked Cesta hrdinov SNP, part of the international E8 long-distance trail.

The summit lies on the red Cesta hrdinov SNP trail; from Donovaly the route over Barania hlava, Kečka and sedlo Hadlanka covers 9.5 km with 540 m of ascent and takes about 3:10 h. A yellow trail bypasses the summit on its northern side, useful in bad weather when the top has no views. Other marked approaches start at Hiadeľské sedlo, Korytnica, Hiadeľ and Moštenica via sedlo Hadlanka.

The summit ridge is built of limestone over crystalline rock, which is why the top is unusually rich in plant species. The northern slopes above the Barboriná valley hold the Kozí chrbát nature reserve. A yellow-marked trail bypasses the summit on the north side, useful in bad weather when the top has no views.
