Sunil Kumar (Tranquility Treks)

Sunil Kumar is a Nainital-born birding and trekking guide who has been leading visitors through the Kumaon foothills of Uttarakhand since around 2001. Operating under the banner Tranquility Treks, he focuses on small-group, tailor-made itineraries for independent travellers who want to pair Himalayan birding with village homestays and short Himalayan treks. His core ground covers Nainital, Pangot, Sattal and the wider Corbett landscape, with longer expeditions reaching up to Pindari Glacier, Roop Kund and the Valley of Flowers. Uttarakhand is renowned for its avifaunal diversity — roughly half of India's recorded species occur in the state, with strong representation of birds of prey and altitudinal migrants. Sunil's local knowledge of trails, seasonality and the resident hill culture lets him work both birders chasing Himalayan specialities and broader nature travellers looking for a culturally rooted week in the mountains.
