The rapid urbanization of cities has increased exposure to environmental stressors such as noise, air pollution, and excessive heat while reducing access to nature, impacting public health. Urban parks serve as “urban oases” that mitigate these issues, but their design faces challenges in dense urban areas. Despite various strategies, the influence of different park types on multi-dimensional comfort—thermal, acoustic, and air quality—remains underexplored. This study evaluates pedestrian comfort in two distinct parks—an elevated urban park and an artificial island—compared to a high-traffic street. Using environmental measurements, walking paths were selected to ensure comparable conditions. Findings indicate that both parks enhance comfort, each excelling in different aspects: the elevated park is praised for its air quality, while the artificial island is noted for its acoustic conditions. Both parks significantly improve air quality, reducing PM2.5 concentrations relative to the street, and provide more stable thermal conditions. While the street exhibited a warming effect of 1.2 °C compared to meteorological stations, the parks offered cooler environments. The artificial island also proved quieter than the elevated park. This integrated approach highlights how urban design influences comfort, demonstrating the benefits and trade-offs of different park types in mitigating environmental stressors.
