In case you are keen to see the night view, there are various travel agents there who can accommodate and provide you a camp at an additional cost. You can set up your camp and enjoy an evening sitting besides the lake and witness the magic of changing colors during sunset.
We happen to visit this place in the month of September and it was pretty cold even during the day. In case you plan to stay back at night, make sure you are well equipped and carrying enough clothes and blankets of your own as well. We chose to drive back but I am sure the night view would be equally mesmerising with a reflection of infinite stars falling on the crystal clear water and maybe spotting shooting stars in between. Hopefully, I will get to see this view as well because this place is definitely worth another visit.
