A planning guide to the Api Himal Base Camp trek — far-west logistics, the Api Nampa permit, wildlife, difficulty and the best time to go.
The Api Himal Base Camp trek explores the almost-untrodden far west of Nepal, leading to the foot of Api (7,132 m) — the highest peak in western Nepal — inside the Api Nampa Conservation Area near the Tibet and India borders. Pristine forest, raging rivers and tiny far-western villages make this one of the country's most authentic trekking experiences.
After a long overland journey to Darchula and the roadhead at Gokuleshwor, the trail follows the Chamaliya river through Makari Gad, Dhuli, Seri and Ghusa, climbing to Kali Dhunga and Api Base Camp (~4,090 m) beneath the mountain's icefalls.
Moderate to Strenuous — altitudes are modest (~4,090 m) so altitude illness is less of a risk, but days are long and the region is remote with basic facilities. Watch for Himalayan tahr, musk deer and blue sheep. Go in March–May or September–November; the monsoon makes the access roads unreliable. Budget 12–15 days including the long drives.
