Error: the central ridge of Muzcev from Kadina to Zajavorja is an alpinistic feat: to the westernmost peak Kadina (1818 m) you can climb from the south (CAI 709, 740), west or north (741, 741/a). In the central part is Vrh Muzcev (1866 m), which is reached by path CAI 737. This path then continues another 500 m to the 1869 m point named Viliki rop (1869 m). It's a nice, slightly spiced tour. Between Kadina and the mentioned Vrh Muzcev, the ridge is exposed and cut with several III-degree spots.
Lopič (1958 m) is the highest peak of the Muzcev group, shifted furthest west, but compared to the central ridge I roughly described above, it's also quite independent. It connects via Slips saddle (1631 m) to Javor (Golz, 1906 m).
Klarman is not Klaraman, but Karman or Veliki Karman (1713 m). This is also the highest peak of the Veliki Karman ridge, which is actually a continuation of the (Breginjski) Stol ridge, but the Ter river has cut a deep valley between them. In short, along this ridge and not the Muzcev ridge runs the so-called "Alta Via CAI Gemona" or "high Humin path" and thus has no connection to Lopič.
My description is given in the following lines:
Starting point: Podbardo (Cesariis, 539 m)

CAI 763, Alta Via CAI Gemona (High Humin path)
Elevation gain: 2000 m
Distance: 20 km
Very demanding marked path, I-degree climbing
Total 13 h
We tackle the tour only if well psychophysically prepared. Helmet use is recommended. No possibility of early retreat in case of sudden weather deterioration. Due to sun exposure, best recommended in autumn.
The grand tour is dedicated to the meritorious member of the CAI section from Humin, Luciano Gubiani, as indicated by the memorial plaque along the path. We do it more comfortably in two days, but if we decide to do it in one day, the prerequisite is above all very good condition. We need to take enough fluids, as there is no spring or intermediate exit on the path where we could end the tour early. The entire tour is marked with both Italian and round Knafelc markings, and on some peaks wooden stakes with red-white stripes are driven into the ground.
The most suitable starting point is Podbardo, where we descend at the end via path CAI 729. This makes the tour end more pleasant, saving another hour of uphill road walking that would await us if we started in higher Breg.
Wherever we start, in front of the last house in Breg there is a direction sign CAI 730, from which we go through several gullies along the Vedronza stream to Predol saddle as at Š-46. At the junction we turn right past the crucifix and up the steep meadow as at Š-55 through the secured Gospodična passage to Veliki Karman. From Breg to here we need 4 h, if we chose Podbardo as start, one more hour.
From the main peak of Veliki Karman we continue east to the slightly more scenic and perhaps even higher eastern peak, where the path turns left and begins to descend to the indistinct, easily accessible Corte peak (1679 m, WGS84: 46.2972°N, 13.1834°E), which it bypasses in an arc on the south side. We descend scenic through several indistinct rocky-meadow-dwarf pine ridge elevations to the slightly prominent Bukovnik (Monte Faeit, 1636 m, WGS84: 46.2977°N, 13.1911°E), the western guard of the Forcja d'Aiar notch (1481 m). From the notch a faint path leads us along a narrow, steep ridge to the top of Ambruž (Ambrusèit, 1640 m, WGS84: 46.2978°N, 13.2013°E; on Tabacco maps the peak is wrongly marked with 1523 m, as it actually has the same height as the further east Siroche Dolegne). To its scenic top we can't avoid a few rock steps.
Now the more demanding part of the tour begins. First we short but steeply descend and ascend several times through successive peaks. From the last one we descend a bit further over short rock steps to a slight flat, from where we continue along a wavy ridge now covered with dwarf pines, later also low trees, towards the cluttered top of Siroche Dolegne (1640 m, WGS84: 46.2968°N, 13.2063°E). From it the markings lead us to a good 10 m deep, exposed, crumbly notch. The descent is somewhat tedious due to scree, but reliable fixed protections help us.
The continuation is more pleasant: the path leads us through several indistinct elevations where we don't lose much height, to the drop of a larger, nearly 100 m long crumbly smooth rock slab (1625 m), which we cross along an exposed ledge. The path continues along the edge of a south-exposed, north dwarf pine-covered ridge interrupted by numerous smaller rock steps. In pleasant climbing we quickly descend, then turn right under the summit ridge of Siroche Gjaline (1581 m). This is quite steep, exposed, on the east side sheer cut and thus impassable. So along a faint track we continue traversing under its grassy slopes for about 400 m, until the path behind one of the numerous edges turns sharply left towards a steep gully. In the keys we climb through it back to the ridge, which further on is fairly narrow and sometimes steep and exposed. Along it we climb through several indistinct peaks to the steep top of Lanež (1629 m).
From its top we descend along the steep, grassy northeast slope, then turn right (Alta Via CAI Gemona actually goes straight through the valley and then through sparse forest to planina Tam za goro or Tasaòro, but since we need to return to the start, we don't follow it). Through sparse forest and dwarf pine belt along the ridge edge we climb to the top of Laški plaz (Monte Laschiplas, 1612 m). From it we descend over a few smaller rock steps and through dense dwarf pines to a larger rock slab and across it steeply up to Postovčič (1611 m), the last peak in the ridge. Follows descent to preval Dolina (Forcella Dolina, 1490 m), where we reach path CAI 729. This descends north to planina Tam za goro, but we continue right through a narrow notch along a very steep grassy slope to Podbardo. If we started in higher Breg, another arduous hour of walking awaits us.
