Nepal conserves huge area of forest and helps in controlling global warming by cutting carbon production. Greenery in Nepal is conserved in the form of national parks, conservation area, wildlife reserves, community forest, hunting reserves and wetland areas. Trekking in those protected forest is a part of jungle trekking we do in packages of Nepalgram.
Apart from those conserved area there are other auto protected region which can be discovered along the trekking route of remote Himalayas in Nepal. While trekking in the remote trekking destinations of Nepal there are many villages with barren lands and those lands are private but after not farming there for years, these lands are now forest.
Trekking has always been through the jungle, in Nepal. If you want to trek all the time inside the jungle you can choose trekking like Mard himal trek or other new trekking routes. If you want to trek in the dense forest then you have to choose something similar to Jattapokhari camping trek or similar camping treks.
Either you trek to famous Annapurna base camp or Everest region trail – forest trekking is partially available in all the regions. The concern among most of the travelers coming to Nepal is either they will want to be in the jungle for most of time or they just want to experience the jungle trekking partially.
Trekking in Nepal has always been into the nature. And jungle has always been inseparable part of trekking activity. But in few cases, there are some trekking destinations like upper mustang and Upper Dolpo where all you see is deserted landscape. Those trekking trails are rain shadow zone and are not for jungle trekking.
In Nepal, Jungle trekking is not possible when you get above the altitude of 4000 meters. From this height no tree zone starts and all you see is bushes and the towering mountains.
