Annapurna Circuit Trek in December

The Marsyangdi side is at its winter best: dry, frozen, empty, and clear. The Ghyaru high route on a still December morning, with almost nobody else on it, is one of the better mornings available in Nepal in midwinter.

The pass through the first two weeks is usually crossable with winter kit and a settled forecast. From around the 20th, accumulating snow on the approach and the ramp above High Camp makes it progressively harder, and the calculation starts resembling January.

Short daylight compounds it. A crossing that takes eight to ten hours from a 4am start is fine in October and tight in late December, when usable light is gone by mid-afternoon and the long descent to Muktinath has to be finished before dark.

Quiet throughout and getting quieter. Lodges up to Manang stay open with reduced service and few guests, and Manang itself is subdued with the seasonal businesses shut.

Above Manang the closures begin. Yak Kharka and Thorong Phedi thin out through December and can shut entirely late in the month, which is a practical reason to cross early rather than a weather one. Confirm what is running before committing to a late-December crossing.

The approach is at its most reliable of the year. Dry, stable roads with no monsoon damage, vehicles easy to arrange at short notice, and a quiet Besisahar. Nothing about December access is difficult; everything about December difficulty is above 4,000m.
