Ensuring equal access to urban parks is vital for sustainable city development. However, prevailing assessment of park accessibility, which mainly rely on spatial proximity, offer a limited perspective by overlooking destination appeal and journey quality. Utilizing social media and street view images, this study proposes a novel multimodal framework that advanced the evaluation of park accessibility from spatial proximity to experiential quality. The framework first integrated online public feedback and offline facility quality using the PCA-AHP-TOPSIS method to evaluate park attractiveness. Then a greenery-perceived distance was proposed by integrating street-level visual greenness and travel distance across three modes to model the perceived impedance of journeys. The effectiveness of the proposed framework is tested in the main area of Wuhan, China. The results reveal that the proposed attraction coefficient correlates more strongly with actual park usage (R2 = 0.68) than area-based metrics (R2 = 0.41). Incorporating GVI significantly improves the explanatory power for visitation frequency, particularly for walking (R2 increase from 0.45 to 0.50) and cycling (from 0.44 to 0.48). GVI's influence varies across travel modes: within a 30-min threshold, walking visitation shows a strong positive correlation with GVI while being weakly affected by distance, whereas distance remains the dominant deterrent for cycling and driving. A pronounced spatial disparity is identified, with 45.3 % of walking zones lacking park access within 30 min, highlighting a mismatch between accessibility and population density. This framework provides practical tools for urban planning and public health, contributing meaningfully to the long-term sustainable development of cities.
