Open and skiing on the lower trails. We have 10km open. Green trails, Woodcock, Snow Goose, Turkey, Blue trails, Grouse, Goshawk and Peregrine. The snow ground up nicely to a sugary, frozen granular. It is very skiable. And even being very skiable it will be fast. Beginners can stick to the flatter loops or try shoe shoeing.
Carry a knapsack. If you overdress you can carry your extra clothes.
When Nordic skiing we all warm up quite a bit. So that makes it a great sport for cold weather (No chairlift). Sweating does happen. A dry shirt to wear for your second lap and/or to wear home is really nice.
