The Annapurna Circuit Trek (ACT) is best done in spring (March–May) and autumn (September–November) when the weather is stable and mountain views are clear. Spring offers blooming rhododendrons, while autumn provides crisp air and excellent visibility. Winter is colder with possible snow at Thorong La, and the monsoon season brings rain and slippery trails. https://nepaltrekkingroutes.com/trip/annapurna-circuit-trek
