Tourism attractions are one of the main elements of the tourism industry, without which it is difficult to create demand and interest for a tourism destination. On the other hand, eco-lodges, which have become common in rural tourism in recent years, are considered one of the most important components of rural tourism development. Without a doubt, creating eco-lodges and creating a platform for their development will have many economic, social, cultural and environmental effects. However, since industrial tourism is competitive and the quality and satisfaction of tourists is an important element in this competition, the present study aims to investigate the factors affecting tourist satisfaction and seeks to answer the question: To what extent does the architecture of eco-lodges affect tourist satisfaction and their desire to stay again? This research was conducted using a descriptive-analytical method and by collecting information in two forms: documentary and survey. Accordingly, a questionnaire to measure the level of tourist satisfaction with the quality of eco-lodges was prepared and standardized using statistical methods. The statistical population of the study consists of rural tourists in 5 ecotourism accommodation centers. To determine the sample size, the Cochran formula for an unlimited population with a confidence level of 59% was used, which resulted in an estimated sample size of 250 people. The data were analyzed with PASW software and the CSM index. The results of this study show that the basic and physical needs indicators had the highest satisfaction and the socio-cultural indicators had the lowest satisfaction.
