The Annapurna Circuit trek is one of Nepal's most well-known treks. There are many reports on the Annapurna Circuit trek all across the world. The hike is an anticlockwise round of one of Annapurna's most prominent mountains. The length of the trek is determined by the mode of transportation employed and the point at which the trek is completed. The highest crossing on this route is Crossing Thorung La Pass, which crosses two distinct river valleys and encircles the Annapurna range (5416m.) The classic trip begins in Besisahar, in the Marsyangdi river valley, and ends in the world's deepest river gorge, the Kali Gandaki. The trail wound its way through rice fields, subtropical forests, stunning mountains, river crossings on steel and wooden suspension bridges, multiple waterfalls, a massive cliff, and diverse ethnic settlements.
