I trekked to Gosaikunda recently. Thanks Third Rock for the best itinerary. I wish I could trek again to Gosaikunda. The lake is supposed to be the home of lord Shiva. This trek is more of religious and spiritual. If you love isolated trail and spirituality, I highly recommend the trek. I did customize my itinerary and the company did their best for me. I loved the trail. It was easy and rewarding.
