42. Adyr­su via the North­ern counterfort of the West­ern edge (combined route by Yu. Kuz­netsov, 3B cat. diff., fig. 5, 6). The path from the “Ullu­tau” al­plager (group of 4–8 people) to the upper pla­teau of the Se­ver­ny Adyr­su gla­cier with the initial bi­vouac on the left-bank mo­re­ne of the Se­ver­ny Adyr­su gla­cier is de­scri­bed in route 43. In the upper part of the cir­que, cross the Se­ver­ny Adyr­su gla­cier (clo­sed cre­vasses) and ap­proach un­der the slope of the ice-and-snow cou­loir on the left side — at the base of the North­ern counterfort of the West­ern edge of Adyr­su peak. From the initial bi­vouac, 1.5–2 hours. From the gla­cier, after pas­sing the berg­schrund:

• 40 m up steep easy rocks on the right side of the ice-and-snow cou­loir,
• then tra­verse 40 m up — left through this cou­loir,

41. Adyrsu via the Western spur of the South Ridge (V. Vyal'tsev's combined route, Category III difficulty, Fig. 5, 6). The path from the Ullutau alpine camp (a group of 4-8 people) to the initial bivouac in the Adyrsu hut is described in route 247. From the hut, descend left onto the Adyrsu Glacier, cross it, and exit onto the left-bank moraine. Follow the trail along the left-bank moraine to the base of the Western spur of the South Ridge of Adyrsu peak. From here, go up and left along the large scree at the base of the Western spur to the platforms near the Red Rocks. An initial bivouac is possible here. It takes 1-1.5 hours from the hut. From the platforms, bypass the Massive Sentinel on the left and ascend on the right side of the wide, gently sloping, and destroyed Western spur, which is simple but has scree in some places. Having passed the Big Sentinel head-on, descend from it to a snowy scree saddle. From the saddle, on the right side of a steep slab, approach the base of the 18-20-meter wall of the South Sentinel of the South Ridge of Adyrsu peak. From the platforms:

• Red Rocks - 3-3.5 hours. The further ascent along the South Ridge to the summit of Adyrsu is described in route 40. It takes 7-9 hours from the hut to the summit.
