Avoid
Lahaul Valley in December
Himachal Pradesh, India
December returns Lahaul to the silence that defined it before the Atal Tunnel existed. Snow buries everything — roads, trails, campsites — and Keylong becomes a small island of human habitation in a vast white emptiness.
The December story
For extreme winter seekers only. December in Lahaul is not adventure tourism — it is an encounter with genuine high-altitude winter, unmediated and unforgiving.
Why December scores 1/5
