Stage 2: Tumling to Kalipokhri (13km, 5–6 hours)

Enter the Singalila National Park properly. You'll dip into Nepal, walk through bamboo glades (prime Red Panda territory), and pass the check post at Gairibas. The day ends at Kalipokhri (Black Lake), a dark, sacred pond surrounded by prayer flags, sometimes glassed over with ice in deep winter, and always atmospheric.

Sleep: Chewang Lodge offers basic rooms and hearty meals.
