There&rsquos a trail in Garhwal that goes up hill, and down dale, through forests of giant rhododendrons and over emerald meadows through the temperate heat of low valleys and the cold of high passes. Cutting across the three river valleys of the Pindar, the Nandakini and the Birehi Ganga in central Garhwal between Gwaldam and Joshimath, the trail culminates in the high mountain pass of Kuari Khal which must boast one of the most spectacular ringside views of the Himalayan Range.
