The Annapurna Circuit trek is one of the most popular and demanded treks in the Annapurna region of Nepal. Travelers have been praising the 128-mile route, which circles Nepal’s heaven-high Annapurna range, as the holy grail of trekking since it was first opened to foreigners in the early 1980s. Sure, there are treks that are more rugged or more remote, huts that are more luxe, pilgrimage sites that are more holy, wildlife that's more exotic, and even scenery–sacrilege!–that's more beautiful. You'll be able to snap photos of the postcard-perfect mountains from the trailhead. But compared to such instant-access treks (the bon-bons of the hiking world), the Annapurna Circuit is a full 12-course meal.
