||Recreational and sport activities in protected natural areas (PNA) have increased in recent years. Protected natural areas are not only promising means to satisfy current health-enhancing physical activity (PA) recommendations, but they also are an ideal environment to promote physical activity (Bedimo-Rung et al., 2005, Mowen et al., 2012). However, few investigations have examined user characteristics and park facilities in relation to park-based PA levels or intensities. The purpose of this study is to examine the influence of PNA visitors (socio-demographic data, recreational behaviour, motivations and preferences) and PNA facilities (PA areas, supporting activities, etc.) in respect to metabolic equivalent (MET) expenditure: sedentary, light, moderate and vigorous activities. The work has prominent potential to help decision makers in developing the sound policy and managerial guidance to increase understanding about the complex relationships between user physical activity level and park amenities.
