On the top, No during winter season you have to take our own tent and pitch it for the night as long as you get a permit from Shamshi Forest Department located just 2km From Bhuntar.
Another option is to do a day hike to Kheerganga and stay in the village just below called Kalga. Kalga is a beautiful small village with a few lovely guesthouses. We stayed one night in Kalga before our trek at a guest house called Gypsy House, it was Rs250 including food.
Happy Travelling!!
