Why winter, and why this pace
December through February — what we call Clear-Sky Bhutan — is the country at its stillest. The festivals are behind us, the trekking circuit is closed, the valleys empty of visitors and full of the cold, dry, blue-skied weather that the Himalayan winter does so well. The cold is real (Paro mornings at minus-eight); the rewards are particular. A retreat in this window has no competition for the guide's attention, no overlap with anyone else's itinerary, and a stillness that you may find anywhere on earth but that costs less here than almost anywhere.
