The creation of ecolodges along with the activities and services that are done to recognize and introduce the environment, are formed in rural and pristine natural areas or historical contexts and are managed by entrepreneurial families and the local community interested in tourism.
By creating conditions for development in small communities, eco-tours lead to local people's income, sustainable development and finally the development of villages. Ecotourism has a prosperous and bright future for local communities and will have many benefits, especially for rural communities and all nature travelers and tourists, and the creation of ecolodges will double this effect. The purpose of this research is to investigate the economic role of ecolodges in the economy of rural households in the eastern Alamut region of Qazvin province at both micro and macro levels. At the micro level, economic opportunities such as accommodation and hospitality services, tourism, and handicrafts are examined, and at the macro level, investment opportunities and the creation of tourism infrastructure are examined.

The investigations and results of the research showed that due to the increase in the number of tourists in the eastern Alamut region, investment in the construction of ecolodges or the conversion of ancestral houses into residences is rapidly increasing, and the only concern in this regard is not observing the correct principles of construction. These ecologies are compatible with the environment. Also, the lack of legal permits from cultural heritage means that tourists who use this type of accommodation cannot follow up legally if they are dissatisfied with the services provided. The noteworthy point is the welcoming of the ecolodges owners to the tourism empowerment training courses, the more fundamental the training, the more tangible its effect in increasing income.
