The capital of Lahaul stretches along one side of the green Bhaga Valley just below the Manali–Leh Hwy, and it’s a popular overnight stop for many buses plying that route. Many travellers only see Keylong briefly and in the dark, but a longer stay reveals grand mountain views, a laid-back village lifestyle and plenty of scenic walks. For tips on day hikes or to arrange longer treks to Zanskar, talk to Amar at Brokpa Adventure Tours in the bazaar (it's under the Hotel Dupchen).
The bus stand is off the highway, just above the main bazaar. At the west end of town is the sort-of-interesting Lahaul & Spiti Tribal Museum, with examples of the distinctive brown Lahauli dress known as a dukpo, plus old dance masks and photos of the local monasteries.
There is a State Bank of India ATM at the north end of the bazaar and an internet cafe opposite the Hotel Tashi Deleg, with wi-fi and patchy connections.
Keylong celebrates the annual Lahaul Festival with a big, bustling market and various cultural activities.
