Tens of thousands of devotees across Himachal Pradesh on Sunday took a dip in rivers braving cold weather to mark the auspicious Makar Sankranti festival. A huge gathering was seen at Tattapani, around 52 km from the state capital, and Manikaran, home to a Sikh shrine in Kullu district, for a holy dip in the Sutlej and Parvati rivers respectively.
