@Muhammad_Irfan aww thank you for mentioning my name I love following your journey. Did you guys pitch tents or stay at the hotel? I saw snow on the ground and in the mountain. With the right equipment you can set up a tent on a snowy ground and have a bonfire in the evening.
Winter camping tradition in our family is in the middle of January where the temperature can easily reach -20C. Not many people camping during winter but it is a wonderful experiences.
Some campgrounds open during winter but in a certain area only. This way it is easy to manage and maintain it. The heated bathroom and heated shower are very helpful. When I go for our next winter camping, I will tag you on my post.
