Most existing research on pilgrims and religious tourists has focused on their motivation, with limited attention to their actual experiences. This knowledge gap is particularly apparent in the Islamic context, where understanding the experiences of pilgrims and religious tourists is crucial for predicting their future behaviors. This paper aims to identify the key dimensions of pilgrims' and religious tourists' experiences during the Arba'een pilgrimage. To achieve this objective, a thorough review of the relevant literature was conducted, and appropriate questions were developed and refined through consultation with experts in the field. The target population for this study consisted of Iranian pilgrims who participated in the Arba'een pilgrimage. The researchers utilized a convenience sampling method to collect 229 completed questionnaires, which were then analyzed using exploratory factor analysis in SPSS software. Through this analysis, the researchers identified six key dimensions that contributed to the experience of Arba'een pilgrims: spiritual and emotional, cognitive, interactive, pleasant, physical-bodily, and learning. This research suggests that while the primary motivation for pilgrims is a spiritual experience, other types of experiences can also enhance their overall pilgrimage experience. These findings have practical implications for destination managers, as they can use them to design various experiences that cater to the needs and preferences of different types of pilgrims.
