Open -1º, at 7am. Expected high 26º. Best skiing of the year. All trails open (Loon is not groomed, skied many times, good skiing). All trails really great skiing, 25km Classic, 5km skate.
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.
