The Annapurna Base Camp Trek is one of the most popular treks in Nepal. It takes you close to Annapurna I (8,091m) and Machapuchare (6,997m), two of the most striking peaks in the Annapurna range.
The trek usually starts from Nayapul and passes through rhododendron forests and Gurung villages. Some routes begin at Jhino Danda or Ulleri, and if you trek via Poon Hill, you start at Hile or Ulleri instead. Along the way, you get both mountain views and a look at local culture.
The trail ends at Annapurna Base Camp itself, sitting at 4,130 meters. From there, you get close-up views of the Annapurna massif.
As you walk, the trail passes through different climate zones. Lower areas have subtropical forest, while the area near base camp turns into alpine landscape. Villages like Ghorepani and Chomrong have teahouses where you can rest and eat. The trail is well marked and moderately hard, so it works well for beginners who are reasonably fit. Still, you need to acclimatize properly to altitude for a safe trek.
