3. Annapurna Circuit, Nepal: Moderate, Varies between 160–230 km (100-145 mi)
The Annapurna circuit is the slightly less crowded, more picturesque, but equally challenging cousin of Everest Base Camp. It’s a tea house trek, meaning that you can leave the tents, cooking equipment, food, and basically everything but clothing and snacks behind.
More of the trek is becoming accessible by road, and what was once a minimum 14-day trek can be shrunk down depending on your time constraints. Though at 5416 meters (17,769 feet) in altitude, the Thorung La Pass is not to be taken lightly. The highest season is in November with April following in popularity.
