Trekking the Annapurna Circuit: What to Know

The full circuit takes 15 to 20 days and requires both a TIMS card and an Annapurna Conservation Area permit, arranged in Kathmandu or Pokhara before you start.

Altitude sickness is the main risk above 3,000 meters, so build in acclimatization days around Manang rather than rushing to Thorong La pass.
