Just as the name means, har ki doon trek is literally walking through the valley of gods . With a detour to ruinsara tal included in the itinerary it becomes extremely strenuous , almost 80 km long but a perfect and complete trek .The way nature keeps rewarding us with her spectacular beauty keeps pushing us all the way up and never lets anyone give up ,no matter how hard they have to push their limits. I still cant quite figure out how our lazy unfit asses were able to complete it , with a 15 kg load on each of our backs .
