🗺️ Itinerary Overview

This is a full round Annapurna itinerary, starting low in the Marshyangdi valley and steadily gaining altitude through Manang before crossing Thorong La Pass into the arid landscapes of Mustang. The route is designed to allow proper acclimatisation, with a dedicated rest day in Manang and progressive daily elevation gain.

Beyond the physical challenge, the trek moves through distinct cultural zones. Hindu villages dominate the lower valleys, while Buddhist communities, monasteries, and prayer flags become increasingly common at higher elevations. The descent to Muktinath and Jomsom introduces a stark change in scenery, with wide river valleys, wind-swept plateaus, and views of Dhaulagiri and Nilgiri.

📍 Location

The Annapurna Circuit spans central Nepal, starting in the Marshyangdi valley and finishing in the Kali Gandaki gorge. It passes through one of the world’s deepest river valleys, flanked by Annapurna and Dhaulagiri.

The route crosses multiple climatic zones, from subtropical forest to alpine desert, offering constant variation in scenery and culture over the course of the trek.

🧗 Prerequisites

While no technical climbing skills are required, this is a long and demanding trek with extended days at altitude. Participants should have strong general fitness and be comfortable walking for 6–8 hours a day over consecutive days.

You must be prepared for high-altitude conditions, basic accommodation, and cold temperatures near the pass. Previous multi-day trekking experience is strongly recommended.
