The trail leading up to Serolsar Lake originates from the right side of the Kali temple (as you face it). There is a small but easy to miss sign in Hindi as well. Fortunately, the trail is well-marked so there is no real need to hire a local guide for this trek. The grassy meadow in the clearing is where the tents are pitched. It was closed when we did Serolsar Lake but I was told by the locals that it is open during the summer months. Barring a couple of points where the trail narrows, this is an easy trek. Assuming a comfortable pace, it should not take you more than 2 hours to reach the lake. Just before you hit the lake, you’ll notice a few gujjar huts on your left. Serolsar Lake is not very large but the setting is quite scenic and serene. Legend has it that there is a pair of birds that keeps the lake clean. On the left bank of the lake is the Buddhi Nagin temple. Ghee (clarified butter) is one of the offerings that devotees make at this temple. Interestingly, large quantities of ghee are poured into the lake as an offering. For night stay, there is a two-room dharamshala (inn) that is available to pilgrims and visitors for a nominal fee of Rs. 20 (to cover your bedding and blanket). You can call the numbers (listed at the bottom of the notice board) to get more information about overnight stay. There is a dhaba (open April to November) which serves tea, maggi, and basic meals. Your return walk from Serolsar Lake won’t take a shorter time because you’ll be ascending for a good bit. Plan on it taking 2 hours to walk back to Jalori Pass.
