Mohe's Santa Claus Village Scenic Area is a deliberately kitschy Arctic-themed attraction near China's northern edge, built around winter tourism, snow, and the novelty of being close to the country's "north pole" region. It is not an ancient sight, but it fits the playful side of a Mohe trip.
The village makes most sense in winter, when the cold and snow are part of the point. In warmer months it is a minor curiosity rather than a reason to travel this far.
