Ladakh's high-altitude Buddhist plateau holds Leh's old town below Stok Kangri (6,153m), the monasteries of Hemis and Thiksey, the Pangong Lake straddling the Chinese border, and Nubra Valley's double-humped Bactrian camels.
Mountain passes (Khardung La, Chang La, Wari La) accessible after snow clears in May, Hemis Festival late June-early July with masked dances, and Pangong Lake at peak.
Peak season with Leh accessible by both Manali and Srinagar highways, Tso Moriri and Pangong roads open, and trekking from Markha Valley to Stok Kangri at year's window.
Heavy snow closes Manali and Srinagar highways October-May, but Leh remains accessible by air year-round, and Chadar Trek on the frozen Zanskar river runs late January-February.
Late season with passes still open, Ladakh Festival in early September, and crisp air giving the year's clearest mountain photography.
