While I am searching for some trekking destinations in South America, it come into my mind that the trekking season in Nepal is starting now. If you are looking for wonderfull treks in Nepal, I recommend Manaslu Circuit and Langtang region treks, which I did last 2 years. They offer fantastic landscapes and no many tourists. Me and my friends did very nice trekking experience with our guides Ashta Lama and Ronik Lama, who are very reliable, experienced and cheerfull people. Great people, great treks!

The Annapurna Circuit if you can get there in the Spring or Fall to avoid the monsoon rains. It's not easy getting from town to town once the rains start. I just did the west side of the Annapurna in June 2016. We went from Dana to Muktinath back down to Jomsom to avoid the monsoon. about 1 year agoAnswered by Beth via WorldNomads.com
