The starting point is in the village of Parva, 17 km away from DN 17D national road. Once you leave the paved road, at the end of the village, follow the forest road along Rebra Valley. In a few hundred meters, the signpost on the left side of the road indicates the starting point of the blue dot trail. The fast waters of Rebra stream are on the right as you walk ahead. After several kilometers, come across the signpost marking the starting point of the trail on Ursului Valley (yellow cross, ongoing project). There is a wooden shelter on the left side of the road. Next, cross the valley to the other side. There are several meadows, a sheepfold and an old forest lodge. From the signpost marking the starting point of the trail on Ursului Valley, walk for approximately 6 more km to Izvorul Negru forest lodge and the intersection with the blue dot trail. The next bifurcation is in the place called Gura Rebra, a meadow with several holiday cottages and a forest range lodge. There is a bifurcation with one road to the left, marked with yellow dot, coming over the hills from Zavoaiele Borcutului meadows, and another to the right, from Rebra Valley. There are power poles along the road from Gura Rebra to Intre Rebre (most of which are now being destroyed). In a larger meadow, on the left side of the road, you can see the ruins of a former building used by the miners in the area. There are also two holes in the mountain. The blue cross trail starts from the place called Intre Rebre, on Obarsia Rebrii Valley. The blue triangle continues for 4 km along the forest road on Guset Valley, then the road disappears, as it has been destroyed. From this point, enter the wild portion of the longest valley in the Rodna Mountains. For about one hour and a half step on the rocks in the water in an attempt to make your way to the initial source of the valley, as the path does no longer exist. The distance between the rocks is sometimes too big, so it is necessary to face the fast and cold waters, deep to the knees. This difficult part ends when you get closer to a sheepfold. The blue triangle trail markers are very scarce and slightly visible. Cross the water one more time and follow the path up to the sheepfold (a newer sheepfold right at the edge of the forest). Walk along the path between the animal pens and the shepherds’ hut. A gradual climb takes you between fir trees for a few hundred meters. This contour line leads to the second sheepfold, just before the beginning of the steep ascent. From here, follow the blue triangle trail. First, walk straight ahead, then cross a creek and move towards the black wooden cross at the foot of the hill that you have to climb. The trail disappears. Try to follow the shepherds’ paths. Trail markers appear occasionally, but they are difficult to follow in bad weather. Gain elevation and, to the right (east), you can see the peaks on the main ridge and on the southern crests (Cormaia, Pietrosu, Tapului). The slope subsides only after one hour, when you get closer to the ridge, which you come across on the road that comes from Batrana Peak. Turn right and reach Tarnita La Cruce after 3-4 minutes.
