For decades, the Annapurna Circuit was widely considered one of the greatest long-distance treks in the world, and while road construction has shortened its traditional lower sections in recent years, the core route — a full loop around the Annapurna massif via Thorong La — remains an extraordinary journey through some of the most varied terrain in the Himalaya.
The trek’s defining feature is its sheer diversity: subtropical forest and terraced farmland in the lower valleys, high alpine terrain and glacial views around Manang, a genuinely serious pass crossing at over 5,400m, and then a complete climate shift into the arid, Tibetan-influenced landscape of the upper Kali Gandaki valley — all within a single continuous trek, the gorge itself the deepest on Earth measured from peak to riverbed.
Sixteen days is a serious time commitment, and Thorong La’s altitude means proper acclimatisation in Manang is non-negotiable; trekkers who rush this stage are the most common cause of altitude sickness incidents on the route. Done at the right pace, though, it remains one of the most complete single treks available anywhere in the world.
