From Zarnesti, go west on Toplita street and 50 meters after the last house leave the road on Barsa valley (Trail 36) and walk along the wide road that gently goes up the northern slope of Piatra Mica mountain to Valea Crapaturii valley (together with Trail 10). After 700 meters, go past the first stone cross and after another 1.7 km you get to the second stone cross and a water source. The wide road gets narrower and turns into a footpath among bushes and solitary trees. After 40-45 minutes from the starting point, you get to a road for articulated forest tractors (TAF). Cross it and walk round the last wooded ridge and get out to Crapatura Valley. Trail 10 continues ahead. Turn left 90 degrees towards Crapaturii Valley. There is a water source after 15 meters. Walk up 15-20 minutes through the deciduous forest and get to the rocky part of the slope. There is a series of 30-40 meter vertical walls to the right (geographically). Climb past them on the scree, pass an area with fallen trees and get to 1380 meters altitude in the coniferous forest . You are on the left side of the valley (geographically). Keep going up on the scree. At 1470 m altitude, Coltul Crapaturii rises to your left, with some rock climbing routes. Go up for 50 meters altitude difference and get on the right side (geographically) of the valley, in a small saddle behind a rocky crest. The switchbacks take you 70 meters altitude difference higher to Saua Crapaturii saddle (intersection with Trails 20 and 21) (1580 m). Next to the saddle, there is a balcony with a panoramic viewpoint of Zarnesti, Crapatura Valley and Persani Mountains. Descend to Cabana Curmatura hut (1470 m) (common route with Trails 20 and 21) through the coniferous forest (southeast) and after the cave wall to the left, turn west and descend on the wooden steps (southwest) (about 30 minutes from Saua Crapaturii saddle). There are many trails coming together at Cabana Curmatura hut: 10, 17 , 18, 20, 21. Continue below the southern slope of Muntele Piatra Mica mountain (above the main spring from the hut) and after five minutes leave the path to Cabana Salvamont Curmatura (Curmatura Mountain rescue hut) to the right and continue on the contour line below Peretele Zanoaga wall towards Poiana Zanoaga meadow. After a 40-45 minute walk from the hut reach the west end of Poaiana Zanoaga meadow, located east from Varful Piatra Mica peak (about 1350 m altitude). After 160 meters, you come across Trail 21 descending from Piatra Mica. Continue on the contour line below Zanoaga rock and after walking 800 meters through the meadow enter the wide corridor through the coniferous forest. Descend on the contour line (50 meters altitude difference), turn left and after 40 meters reach the meadow next to Padina lui Danisor (water source!). Continue on the right side of the meadow on the descending switchbanks on the rocky crest and after about 930 m (170 m altitude difference in descent) leave it for a gentle descent along Padina lui Danisor stream. Turn right (east) and after 500 meters reach Fantana lui Botorog meadow (connection with Trails 10, 12 , 22, 23). From here, follow the road for 1.6 km to Cabana Gura Raului hut (sign panel).
