GHANDRUK by Road travel, NEPAL

Road Travel To Ghandruk, NEPAL

Ghandruk is a famous tourist destination in Nepal. Trekking starts from NAYAPUL, Myagdi, nearly 40 Km from the POKHARA. There is many buses and taxis that run from Pokhara to Nayapul. A gravel road extends from Nayapul to Kimchi of Myagdi district. Length of the gravel road is nearly 16 km. There is some buses and Jeep running between Nayapul and Kimchi. The fare is reasonable. It costs just NRs. 300 (~ US$ 4) to reach Kimchi. But road is bumping and widespread dust.  Ghandruk can be reached after an hour walk from the Kimchi. Newly opened track is closed during the rainy season.
