Trek from Chhokangparo to Nile/Chhule
From Chhokangparo we trek to Nile/ Chulle. This is the last village heading north in the upper Tsum Valley. Nile is on the western, sun-side of the Shiar Khola, about 20 minutes walk across from Chhule. On the way we pass the Piren Phu cave. Piren Phu (pigeon cave) is one of the most sacred caves in the Tsum valley. It is located at the foot of a rugged cliff near the village of Burji. Milarepa, the famous Tibetan saint, was believed to have meditated here. There are two separate gumbas attached to the rocky cave. Richly painted Buddhist murals, excellent artistic scripts carved on stones, long prayer flags and significant Buddhists paper scripts make this cave one of the most important socio-cultural asset in the valley.
Beautiful views can be had of the Shiar Khola, Rachen Gumba, the mountains and settlements amidst vast agricultural land.
