Urban green spaces are increasingly recognized for their capacity to support mental health and enhance positive affect through interaction with nature. As a significant component of urban green infrastructure, urban forests provide restorative environments that contribute to individuals’ subjective well-being. This study investigates the effects of quality of experience in urban forest visits on individuals’ restorative experiences and subjective well-being levels. Data were collected via a structured questionnaire from 385 participants who visited an urban forest and analyzed using structural equation modeling (SEM). The findings reveal that quality of experience exerts both direct and indirect positive effects on subjective well-being, with restorative experience serving as a partial mediator in this relationship.
