The Biafo Glacier ({{langx|ur|{{nq|بیافو گلیشیر}}}}) is a glacier located within the Karakoram mountain range in the Hispar Valley, Nagar District of Gilgit-Baltistan, Pakistan. It extends over a considerable distance, measuring {{convert|67|km}} in length, and ranks as one of the largest glaciers in the entire Karakoram range. Flowing in a south-eastern direction from the central Karakoram crest, the glacier covers a basin area spanning {{convert|853|km2}}, of which {{convert|628|km2}} are characterized by permanent snow and ice. The accumulation zone alone contributes to 68% of the glacier's total area.{{Cite journal |last1=Hewitt |first1=K. |last2=Wake* |first2=C. P. |last3=Young |first3=G.

Geography

Biafo Glacier converging at Hispar La with {{convert|49|km}} long Hispar Glacier situated at an elevation of {{convert|5128|m}}, forms the glacial system considered as the world's longest non-polar glacial system which spans an overall distance of around {{convert|120|km}}.{{cite web|url=http://www.thenews.com.pk/Todays-News-6-201634-Biafo-Hispar-glacier-trek-completed |title=Archived copy |accessdate=2014-02-16 |url-status=dead |archiveurl=https://web.archive.org/web/20140222182020/http://www.thenews.com.pk/Todays-News-6-201634-Biafo-Hispar-glacier-trek-completed |archivedate=2014-02-22 }} This frozen pathway links two ancient mountain regions, connecting Nagar in the west with Shigar District, Baltistan in the east. Approximately, 20 kilometers (12 miles) from the village of Askole in Braldo, Shigar District, this glacial junction is found. The entire journey spans 100 kilometers (62 miles), utilizing 51 kilometers (42 miles) of the Biafo Glacier and the entirety of the Hispar Glacier.

Snow Lake, consisting of parts of the upper Biafo Glacier and its tributary glacier Sim Gang, is one of the world's largest basins of snow or ice in the world outside the polar regions, up to {{convert|1,600|m|mi|abbr=on}} in depth.

The Biafo Glacier is the world's third longest glacier outside the polar regions, second only to the {{convert|70|km|abbr=on}} Siachen Glacier, contested between Pakistan and India, and Tajikistan's {{convert|77|km|abbr=on}} long Fedchenko Glacier.

Campsites along the Biafo are located off the glacier, adjacent to the lateral moraines and steep mountainsides. The first three (heading up from the last village before the glacier, the thousand-year-old Askole village) are the sites with flowing water nearby. Mango and Namla, the first two campsites, are often covered in flowers and Namla has an waterfall very close to the camping area. Baintha, the third campsite, is often used as a rest day. A large green meadow has a few running streams near the camp and many places to spend the day rock climbing or rappelling.{{cn|date=December 2024}}

Evidence of wildlife can be seen on the trek, including Ibex and the Markhor mountain goat. The area is also known for Himalayan brown bears and snow leopards, although sightings are rare.
