For this Trip you need to be physically fitness and mentally well prepare. Some days you need to walk 8 to 9 hours, which is more than average walking in a day. It could do just Camping organize trip last three years ago but there is basic Teahouse entire trip now a days.
Mostly, you will stay in Lodge and having food same place (Dhal Bhat=main Nepali food, Fried rice, Bread, Boiled and fried eggs, Potato, Noodles, porridge, tea coffee tec.) But if you have additional some days you may visit Tsum Valley area also, this is home stay trip (where you can have the food there at someone house and provide accommodation). If you have time, I would like recommend you Tsum Valley too; which is itself restricted area and open since 2007. This trip is combination of cultural and religious, which is a unique trip among numbers trekking trail of the Nepal.
