This 7-day circuit combines the high-altitude grandeur of East Sikkim with the rich subtropical forests of West Bengal's Himalayan foothills. Beginning at Padamchen in Sikkim, the tour ascends through rhododendron and conifer belts to seek out pheasants, tragopans, and alpine specialists before descending through Dikling and Khemshika to the legendary birding grounds of Latpanchar. The dramatic altitudinal gradient — from over 3,000 m to under 800 m — delivers an extraordinary diversity of Himalayan birds across just one week.
