The benefits of physical and outdoor recreation on human health and well-being cannot be overemphasized. Nature parks are places for people to recreate, connect with nature, have fun, and find mental, physical, and spiritual health and social well-being. The implication of outdoor recreation on human health was investigated in this study using Lekki Conservation Centre (LCC) and Lekki Urban Forestry and Animal Shelter Initiative (LUFASI) in Lagos State, Nigeria. A well-structured questionnaire was administered to 200 respondents at both sites, and data were analyzed with descriptive statistics and Chi-Square. Findings revealed thirteen (13) recreational resources in LCC and ten (10) were identified in LUFASI nature parks (categorized into both natural and non-natural attractions). Furthermore, a higher percentage of the study respondents were female (51%), singles (56%), and 65% were 18–45 years old. In
addition, 51.5% have had between 6 and 10 years of outdoor experience, and most visitors travel with their families and friends. Observing nature, wildlife, forest, wildflower, and outdoor court games prompted their visit to outdoor recreation nature parks. Moreover, spending time with family and friends (4.47) was their major motivation for outdoor recreation participation. The most significant health benefit attained by visiting was social well-being (38%), followed by physical well-being (34.5%) and mental well-being (27.5%). Nature encourages more social interaction and brings people together had the highest mean value (4.32) for social health implication, physical health implication was “improved physical wellness” with a mean value of 3.78, and the mental health implication was that “activities in the natural environment improves mood” with the mean value of 3.89. Furthermore, 91% of the visitors to these nature parks were satisfied and pledged their loyalty to revisit and recommend the parks to others. A significant relationship exists between visitors’ motivation for nature park outdoor recreation and their age (χ 2=75.530, p=0.014) and education (χ 2=74.064, p=0.019). Hence conservation of more green areas is hereby encouraged to harness the health benefits these sites provide.
