Our Lantang valley trek with Index Adventure was nothing less than fantastic. With the company's informed advice, we managed this trek to best fit our requirements. I mean they were not just quick to respond but equally competent with the knowledge necessary. Personally, I am confident that only a local company with local connections can provide such advice with such conviction and certainty and, for us, Index Adventure was the one. During the trek, we stayed in reasonable teahouses, had our Dal-Bhat for that energy, chatted with the locals (of course, with the help of translations from our guide), walked those alternate ascents and descents, were surrounded by massive elevations, and were blown away once atop Tsergo-Ri.
