Mardi Himal Trek is a good alternative to escape away from crowded treks of Annapurna with stunning views and duration similar to Ghorepani Poon Hill Trek. Mardi Himal Trek is a relatively new trekking route in Annapurna region with spectacular views of the Annapurna Himalayan range. It's a peaceful trekking route with very few trekkers along the way. Though the availability of foods and accommodation on the route is at the bare minimum, Mardi Himal Trekking is still an enjoyable trekking route which requires minimum effort.
From High Camp (3580 m; some maps incorrectly mention 3900 m) you can climb up to Mardi Himal Base Camp in about 3-4 hours, which offers spectacular close up views of the entire Annapurna Range. There are simple guesthouses and homestays along the entire route. If you plan to do this trek in the winter months please check with a local tour operator if the lodges are open.
