Jepi Mari trail connects Busteni to Piatra Arsa via Jepi or Schiel Forest Lodge (the Naturalists 'House), as it was when called when the path used to zig-zag below Schiel brothers' ropeway. Along with Jepii Mici, it is one of the most popular routes in the Bucegi Mountains. Note that the route is accessible only in the summer, as there is risk of avalanche during the winter months.
Jepii Mari are much more accessible than Jepii Mici, even if they have cliffs and chain sections, they do not pose major technical difficulties, the path zig-zags up and the more difficult parts are equipped with cables, so the trail can be done by a wider category of tourists. Throughout the trail you will marvel at the view you see between the leaves of the trees. It is so quiet that in the middle of the route you can still hear the sound of the cars down in the valley on DN1 national road.
The trail first takes you through the hardwood forest, then through the coniferous forest, between dwarf pines, and through the alpine meadow on top of the plateau. After another twenty minutes of walking on mountain trails, you reach Piatra Arsa Hut.
The starting point is Busteni cable car at an elevation of 880 meters, facing the steep Bucegi Mountains, dominated by Claia Mare Peak and Caraiman Peak, and up to a point the route is common with Jepii Mici trail and Urlatoarea Waterall trail. The trail crosses "La Vinclu" area (intersection with trail 5), then "La Mese" point, where you can admire Claia Mare and its gigantic wall and then it enters the most difficult part, "La Scari". On the edge of the path you can see two crosses in memory of those who tried to do the trail in bad weather.
There are several stone thresholds equipped with cables fastened to the rocky walls and then you walk through dwarf pines in Urlatoarea Valley, parallel to the ropeway that once carried wood to Jepi/Schiel Forest Lodge at the elevation of 1,960 meters. Pay attention as trail markers are scarce!
Schiel Forest Lodge, which houses the Naturalists' House, dates from 1910 and it was built by Schiel brothers, the founders and owners of the paper factory in Busteni. Although deserted, the construction is solid, partially degraded, and its position at the edge of the steep slope offers an impressive view of the Prahova Valley, Bucegi and Baiului mountains. From here you can see Caraiman Peak, the Heroes’ Cross, Jepii Mici, Claia Mare and other peaks. From the forest lodge you can continue along the Bucegi Plateau to get to Babele Hut (trail 37) for 1 hour and 30 minutes or to Caraiman Hut for 1 hour and 30 minutes.
From here, the trail continues through dwarf pines to Piatra Arsa Hut for 20 minutes (connection with trail 37). The cabin is located on the Bucegi Plateau, at an elevation of 1,950 m, halfway between Babele and Cota 2,000 elevation. Built in 1935, it was later transformed into a sports base. Numerous athletes come to train at Piatra Arsa National Sports Complex every year.
