There is one trek on earth where you camp surrounded by four 8,000-metre peaks, and this is it. The K2 Base Camp trek follows the Braldu River and then the Baltoro Glacier from Askole — the last village, reached by jeep from Skardu through Shigar Valley — to Concordia, the great ice junction where the Baltoro meets the Godwin-Austen Glacier beneath the full south face of K2 (8,611 m), the world's second-highest mountain.
Concordia's nickname, the 'throne room of the mountain gods', was coined by photographer Galen Rowell, and no one who stands there argues with it. Within a single panorama rise K2, Broad Peak, Gasherbrum IV's shining wall and the Gasherbrum giants behind, with Mitre Peak as the gatepost — the densest gathering of high mountains on the planet.
The classic itinerary takes about 12–14 days round trip from Skardu: jeep to Askole, then stages through Jhola and Paiju, onto the glacier past the granite cathedrals of Trango and Cathedral Towers, to Urdukas, Goro II and Concordia, with a day's extension up the Godwin-Austen Glacier to K2 Base Camp itself. Strong parties can return via the 5,585 m Gondogoro La to the Hushe Valley near Khaplu, swapping a re-walk of the Baltoro for one savage, spectacular pass day.
Make no mistake about the grade: this is a strenuous expedition-style trek, with long glacier stages, nights at 4,000–4,800 m, river crossings and weather that can pin you down. Yet it is non-technical — thousands of fit trekkers complete it each season with no mountaineering skills, supported by Balti porters whose hardiness is the trek's quiet wonder.
Logistics are real but manageable: foreigners trek with a licensed operator and guide, permits and a trekking fee are arranged through Skardu, and the season runs from mid-June to early September. Build in spare days for flights and weather, and spend them well in Shigar or Khaplu on either side of the walk.
