Čaven, Mountain summit in Vipava Valley, Slovenia

Čaven is a ridge above the Vipava Valley forming the southern rim of the Trnovo Forest Plateau. Its highest peak is Veliki Modrasovec at 1353 m, with Mali Modrasovec at 1305 m and the most scenic Kucelj at 1237 m; the western peak named Čaven reaches 1185 m. The ridge is built of upper Jurassic limestone, and between Veliki Modrasovec and Mala Gora stands the Anton Bavčer Lodge.

Čaven is built of Upper Jurassic limestone, and next to the road on Selovec there is a prominent reef limestone site with fossils of coral colonies and hydrozoans. The ridge forms the southern rim of the Trnovo Forest Plateau in the northern Dinaric Alps.

Čaven's slopes are the growing site of the endemic perennial Hladnikia pastinacifolia, a plant found in Slovenia's karst uplands. Near the road at Selovec, a reef limestone outcrop preserves fossils of coral colonies and hydrozoans. The Anton Bavčer Lodge stands between Veliki Modrasovec and Mala Gora, a stopping point on the ridge.

Trails reach the ridge from Predmeja, Stomaž and Lokavec; the ascent takes several hours, so wear sturdy footwear and carry enough water. Between Veliki Modrasovec and Mala Gora stands the Anton Bavčer Lodge at Čaven, a staffed hut where walkers can rest and get refreshments.
