As a core and long-established part of urban blue-green infrastructure (BGI), public parks play a significant role in the sustainable development of cities. In particular, they make a major contribution to maintaining healthy ecosystems and providing multiple benefits that support human health and quality of life as a kind of nature-based solution (NBS). Still, planning, design, and management of public parks mostly rely on official standards and technical guidelines, whereas societal perspectives and the use of the ecosystem services (ES) approach (and cultural ecosystem services (CES) in particular) remain inadequately integrated. By assessing CES offered by Gorky Park in Moscow (Russia), the paper aims to bridge this gap and investigate the flow of CES and its relation to park infrastructure and the visitors' needs. For this purpose, non-participant observation, field notes, and photographs were used in different functional park zones. By investigating visitor activities and factors affecting them, a variety of CES provided by the park have been detected. As aligned with its original idea, the park was mostly used for recreation, leisure, sports, and socializing. Moreover, the CES related to aesthetic, educational, and cultural heritage values were also partially utilized. The park was mostly attractive to the younger generation (the highest number of visitors), whereas visitors over 60 years old were hardly represented. Notably, men were more interested in sports (especially, team sports), whereas women mostly preferred walking (alone, with family, and with friends), relaxation, playing and spending time with children, picnicking, etc., which indicated certain preferences for CES among the park visitors. An interdependent relationship between the CES supply and the park infrastructure was found: the more infrastructural components were identified, the greater variety of park activities and corresponding CES were detected at certain observation points, which could ultimately lead to overcrowding and overutilization of the ES capacity. Given that the Moscow government claims integrating ES into the planning and management of urban BGI as one of the priorities in the city's environmental policies, the related recommendations are provided. They address the recent challenges of creating integrated BGI, increasing demand for multifunctionality, and the conflicting interests of different visitor groups to maximize the benefits and diversity of CES delivered by the park.
