Uli Biaho Tower (6,109m) and its neighboring sister peak, Uli Biaho Prime (6,158m), represent some of the most striking, uncompromising vertical granite obelisks in the Karakoram range. Situated just west of the Trango Towers near the mouth of the Trango Glacier, Uli Biaho rises directly above the convergence of the Trango and Baltoro glaciers in Gilgit-Baltistan’s Shigar District.
Renowned globally for its iconic, sheer 1,000-meter East Face, Uli Biaho is a legendary big-wall alpine objective that demands technical rock climbing mastery, portaledge living, heavy haulage, and high-altitude endurance. We provide end-to-end Base Camp and operational logistics—including official climbing permit clearances with the Gilgit-Baltistan Tourism Department, 4×4 road transfers, experienced local Balti high-altitude staff, kitchen crew, and complete Base Camp setup.

Route & Climbing History: Uli Biaho Tower achieved legendary status in 1979 when Americans John Roskelley, Kim Momb, Ron Kauk, and Bill Forrest completed the first ascent via its formidable East Face (A3, VII, 5.8) over 12 continuous days on the wall—a watershed moment in high-altitude big-wall history. Subsequent routes on the Uli Biaho massif continue to challenge top-tier international teams with sustained vertical crack systems, high exposure, mixed ice/snow couloirs, and severe Karakoram weather.
Climbing grade: Extreme Big-Wall / High-Altitude Alpine Rock Climb (ED+ / VI 5.11–5.12 / A3–A4) — glacier approach via Askole, vertical haulage logistics, portaledge camping, fixed lines, and continuous technical rock climbing over 6,000 meters. Designed exclusively for expert big-wall alpinists.

A: Uli Biaho Tower is located on the north side of the Baltoro Glacier near the mouth of the Trango Glacier in the Shigar District of Gilgit-Baltistan, Pakistan. Its exact summit elevation is 6,109 meters (20,042 feet).
A: The optimal climbing window for Uli Biaho runs from mid-June to late August. During the Karakoram summer, snow retreats from vertical granite crack systems, and temperatures on wall ledges (4,000m–6,109m) are manageable for big-wall hauling and portaledge camping.
A: Overseas mountaineers require an official trekking permit issued by the Gilgit-Baltistan Tourism Department, a Non-Objection Certificate (NOC), and a Pakistani Trekking/Mountaineering Visa. Skardu Expedition Treks and Tours handles all official royalty clearances, government briefings, arrangements, and local porter logistics.
A: Following a 4x4 jeep drive from Skardu to Askole (3,000m), the approach trek takes 3 to 4 days along the Braldu River and lower Baltoro Glacier to reach Uli Biaho Base Camp (4,000m).
A: Skardu flights are weather-dependent. The itinerary incorporates built-in overland transfers via the Karakoram Highway (or Babusar Pass) with an overnight stop in Chilas on Days 2–3 and Days 31–32 to ensure guaranteed connections to Islamabad regardless of flight status.
