The Annapurna Treks
There's the trek up to Annapurna Base Camp heading to just over 4000m where you also get to view the giant Annapurna peaks above you. Then you've got the challenging but epic Annapurna Circuit trek where you trek right around the massif and over Thorung La Pass.
Whichever trek you'll take on, this trekking area is one fantastic place to visit.
