Nagini to Choi Waterfall Trek Another of my favorites, this 30 minutes hike from Nagini Village. There is a well defined trail leading upto the waterfall where you can spend your evening and return the same day. The sad part Tirthan Valley has become a victim of irresponsible tourist activities. In last two years, the number of plastic waste, empty beer bottles and leftover food has simply gone up the peak. Despite a UNESCO protected region, there is no one to make sure that the mountains stay the way they are supposed to be. There are cleanup drives in the valley that offer trekking activities in return of volunteers bringing plastic waste. This is also a great way to explore the beautiful Tirthan and generate some good Karma.
