The restricted region is the trekking region of Nepal that is far away from today's modernization. These are also the region which sees very few numbers of visitors, so they include one of the remote trekking trails of the world. The places might be remote yet they are rich in mountain beauties, glaciers, lakes, rivers, and cascades. Likewise, the local settlements with their unique ethnicity make them the untraced paradise on the earth. These hidden valleys have special conditions if you plan on visiting them. You will have to obtain a special restricted trekking permit to visit those areas. Also, you should know you can't visit these places alone: you will need to take a licensed guide or porter along with at least two travelers.
