Boč, Mountain summit in eastern Slovenia.

Boč is a 978-metre forested mountain in eastern Slovenia, the central peak of the Boč–Donatus Mountain Landscape Park. It has two summits about five minutes apart: one carries transmitters in a restricted military area, the other a 20-metre lookout tower built in 1962. St. Nicholas Church and the Hut Under Mt. Boč stand on a saddle at 658 metres, not on the summit.

The 20-metre steel lookout tower on one of the two peaks was erected in 1962, and a television transmitter was later built nearby on what is now a closed military area. The Church of St. Nicholas stands below the summit on a saddle at 658 m, next to the Planinski dom na Boču mountain hut and the landscape park information centre.

St. Nicholas Church stands not on the summit but on the saddle at 658 m, next to the Planinski dom na Boču and the Boč Landscape Park information centre. The protected Greater Pasque Flower (Pulsatilla grandis) grows near the church and the hut on the southern slope; a sculpture of the flower by Franc Tobias of Razvanje is displayed on a small rise near its growing site.

Several marked trails lead to the summit from different starting villages, so visitors can choose a route based on their energy and time. The climb is demanding and sturdy footwear is strongly recommended, as the forest shade does not fully reduce the effort on steeper sections.

The Greater Pasque Flower (Pulsatilla grandis), a protected species, grows near St. Nicholas Church and the Hut Under Mt. Boč on the southern slope. A sculpture of the flower by Franc Tobias of Razvanje stands on a small rise near its growing site. The mountain also shelters Slovenia's only known population of Tetrix transsylvanica, a small groundhopper.
