Hey Devi, At this time, it will be beautiful,peaceful,less crowded and budget trip. Pack your winter clothes like jackets,inner warmers,woolen socks,gloves,woolen cap,moisturizer,first aid kit etc. Main thing in Kashmir is road trips (Srinagar->Pahalgam and Srinagar -> Gulmarg). And stay at houseboat in Dal lake. You can also get snowfall there. Hope this would help you.
