Almost in all popular trekking trails in Nepal (Everest, Annapurna, Langtang), local villagers have built tea-house lodges. In tea house trek you stay at those mountain lodges and have breakfast, lunch and dinner in their restaurant. Normally the tea houses are more like hotels with hot showers, continental and Nepali food and comfortable private rooms (twin sharing). If you stay in local hotels, you will also get an opportunity to interact with local hoteliers and their family members and get information about their lifestyle and culture.
