Route description by sections
Approach to the route:
From the base camp, follow a good path, bypassing the western slopes of p. Solidarnost on the right, ascend the moraine under the North wall of peak Arsen (3–4 hours).
R0–R1. The route begins to the left of the prominent monolithic triangular massif at the base of the wall, bounded on the left by a scree couloir. Up the wall with "ram's foreheads". R1–R2. Up the wall with "ram's foreheads", trending left. R2–R3. Continue up the wall with "ram's foreheads", exit onto an uncomfortable ledge. R3–R4. Traverse left along the uncomfortable ledge to a niche. R4–R5. Behind the niche at the end of the ledge begins the "Book" (R4–R8). At the start of the "Book", climbing is not complicated, but there are "live rocks". R5–R6. The "Book" becomes steep 80–85°, rocks are monolithic. R6–R7. Up the inner corner to a cornice. R7–R8. Bypass the cornice on the left, then up the inner corner, trending left. R8–R9. A gentle inner corner formed by two monolithic slabs, trending left. R9–R10. Then exit onto a vaguely defined rib and up. R10–R11. The rib abuts "ram's foreheads", at the foot of the "ram's foreheads" is a control cairn, to the right of it – two black waterfalls. R11–R12. Climb the "ram's foreheads" to enter an inner corner. R12–R13. Up the inner corner to reach a scree ridge. R14 – summit. Along the broken ridge and scree slope 500 m – exit to the summit.
Description of the descent from the summit. Descent from the summit initially follows the ascent route along the ridge, then left-down (in the direction of travel) into the "Wild Climbers" valley.
