Regional overview

This selection treats the Eastern Himalaya as a cross-border walking region: Bhutan’s monastery and high-pass forests, India’s Singalila/Sikkim rhododendron belt, and Nepal’s Kanchenjunga high-alpine approach. Goecha La was excluded as a full trek and Pangpema is used only as a one-day section from Lhonak.

Selection rationale

The five routes cover the most distinctive day-walking categories of the Eastern Himalaya: Bhutan’s cliff-monastery objective, a high-pass forest viewpoint, a rhododendron-and-Kanchenjunga ridge in Singalila, a Sikkim rhododendron sanctuary walk, and a single high-altitude moraine day from Lhonak to Pangpema.
