Keylong is the administrative capital of the Lahaul-Spiti district in Himachal Pradesh, perched at 3,350 metres in the valley of the Bhaga River. It sits on the Manali–Leh highway and makes a natural overnight halt for travellers on that spectacular route — a chance to acclimatise before pushing higher toward Ladakh.
The town is small and surrounded by terraced fields of barley, buckwheat, and potatoes spreading up the hillsides. Tibetan Buddhist culture is strong here, owing to the proximity of Tibet, and several ancient monasteries (gompas) dot the surrounding valleys. Kardang Gompa (8 km), the largest in Lahaul, has a fine collection of Buddhist scriptures and thangka paintings. Closer to town, Shasur Gompa (3 km) and Guru Ghantal (4 km) are also worth the walk through the villages.
The season is short — the Rohtang Pass connecting Keylong to Manali typically opens in June and closes by October, and the road north to Leh via Baralacha La is passable only from late June to September. In winter, Keylong is largely cut off, though the Atal Tunnel (opened 2020) now provides year-round access from Manali.
