Gornja Trnava – Mađarev Brijeg – Hunjka

Walk along Markuševečka Trnava street until you reach the hamlet of Toti. The trail is well-marked, with signs along the way. Continue on Toti street until the end of the asphalt road, where you’ll find the Prigorje hunting lodge. Proceed along the gravel road next to the Trnava stream. There are beautiful meadows and several small bridges along the stream. You’ll gradually enter the forest. At the intersection of two forest roads, turn right. Here, the Stari (Old) and Novi (New) streams converge to form the Trnava stream. There is also a signpost for Gorsko Zrcalo rock (Mountain mirror). On your right is the Sv. Juraj picnic area, a private property open to visitors by the owner's permission. Continue on and you will come to the Gorsko zrcalo climbing practice area and the Milanovo skloniste shelter, which is located right on the stream.

Gorsko zrcalo is a vertical smooth rock wall about 20 metres wide and high. This monolithic cliff is unique to the Medvednica area. In geological terms, a “mountain mirror” refers to a smooth, nearly flat rock face formed by fault movement. It is used for rock climbing and speleology training. Nearby is the Milan rest area, named after Milan Matovina, an alpinist who died in 1978 in the Canadian Rockies. The Novi stream flows just below the terrace.

The area around Gorsko zrcalo and the Milan shelter is beautiful and ideal for a day trip. It takes about 45 minutes to reach this point from the bus stop, and this flat section is suitable even for families with small children.

The trail then continues alongside the Novi stream. A narrow path about 400 metres long winds through the canyon of the Novi stream. After this flat section, the trail turns left uphill and reaches a wide forest road near a stone water management facility. Walk straight along the road (the fenced facility will be on your left). Continue past it, and in a sharp left turn the climb begins towards Cer hill, leaving the Novi stream behind. This section becomes challenging due to the constant ascent with few flat spots to rest. Take your time here, as you will soon reach a long and steep slope known as Tisova Peć.

After that, you’ll come out onto Markuševec gravel road, where you turn right toward a large curve. Here, take the left fork of the road that descends from the Hunjka forester’s lodge and continues toward the Gorščica forester’s lodge. Walk another 200 metres along this road, and at the next junction enter the forest again via a hiking trail. Another uphill section awaits, though much gentler than the previous climb. Eventually, you'll reach the ridge, where the trail flattens out beautifully. The trail runs through a lovely deciduous forest of beech and hornbeam, and then, upon reaching Mađarev breg, it enters a coniferous forest and leads to the Ornjak shelter. You’ve now reached an elevation of 900 metres and covered more than six kilometers. This is where trail no. 23 ends.

Near the Ornjak shelter is the Hunjka forester’s lodge. There's also a trail junction here: trail no. 109 to the right leads to Gorščica (1 hour 30 min) and to the left it continues toward Hunjka forester’s lodge (20 min).

This trail is the easternmost approach to the central part of Medvednica, and due to its difficulty, it’s sometimes overlooked. However, it’s considered one of the most beautiful trails on Medvednica. The trail can be divided into two parts: the first, flat and easy section up to Gorsko Zrcalo, and the second, steep section from there to Hunjka, which allows few breaks except on the Markuševec gravel road and at the ridge. Because of the constant ascent in the second half and its overall length, this trail is fairly demanding. Don’t go down using this trail, precisely because of the steep sections.
