Annapurna Circuit Trek constantly shifts climatic zone, vegetation, and weather patterns. The trekking adventure begins in a lush subtropical setting where, in the pleasantly warm weather, you cross numerous terraced farms and fields. Trekkers see several Himalayan communities built in a conventional manner. Then, among chilly deciduous forests, you approach the Marsyangdi river valley. You will find subtropical plants such as birch, oak, juniper, and rhododendron thickly forested in most of the woodlands you traverse.
After a few days, the Annapurna range will come into view which has the highest mountain in the area, Annapurna I (8,091 m), and the tenth-highest peak in the world. Once you get over the tree line, you will see desolate ravines and parched slopes surrounded by snow-capped summits. The Manangis, or people of Manang, live in a sparsely populated location where there is sometimes a fierce wind in an area of the Himalayas that resembles a desert. The Khatung Kang and Yakawa Kang mountains meet at the mountain pass known as Thorong La (5416 m), which is the highest point of the Annapurna Trek.
Thorung La Pass offers views of the magnificent, desert-like Himalayan slopes, that are distinguished by their unusual purplish hue. The remainder of the journey is mostly a decline till Jomsom. Once again, you will leave the alpine setting and pass through a profusion of subtropical vegetation going uphill and downhill before reaching Pokhara's stunning Valley of Lakes.
