Veternica Cave and Glavica

Veternica is the longest cave on Medvednica and sits in the western part of Medvednica Nature Park, above the Gornji Stenjevec district of Zagreb, Croatia. The approach on foot is short: ZET bus 124 runs from Črnomerec to Gornji Stenjevec in about 15 minutes, and trail no. 3 then climbs roughly 2 km, gaining 150 to 200 m, to the cave entrance in about 20 minutes. The bus terminus serves as the trailhead, and parking is limited, so most visitors arrive by public transport. Timetables are available at zet.hr. Guided tours of the cave run on Saturdays, Sundays and public holidays from 10:00 to 16:00, last about 45 to 60 minutes, and are booked with the park on +385 1 4586 317, answered on weekdays from 08:00 to 16:00. Visitors should confirm the schedule before traveling because tours depend on season and conditions. The surface on trail no. 3 is a forest path of packed earth, roots and stones that can be muddy after rain. There is no exposure or scrambling, and shade from the surrounding woodland keeps the climb cool in summer. Inside the cave, the temperature stays around 10 C all year, passages are damp, and the guided section includes stairs and narrow stretches with rock formations. Veternica is also known as a roosting site for bats and a protected site, so visitors follow the guide's instructions and avoid touching formations or disturbing wildlife. The cave entrance is the natural turn-around point for walkers, though the area above, known as Glavica, offers further marked paths along the slope for those who want a longer outing. There are no refuge huts along this short approach, and walkers should carry their own water. Because the cave tour is the main attraction, the day works best planned around the tour start time rather than the hike itself. The nature park authority publishes visitor information on its official website, and sturdy shoes and a warm jacket are the main equipment needs.
