To further objectively understand the suitability of forest park health tourism development, this paper selects 11 national forest parks from five regions in Jiangxi Province: Gandong, Gannan, Ganxi, Ganbei, and Ganzhong. Based on criteria such as forest quality, environmental quality, infrastructure construction, and resource value, a hierarchical evaluation index system for forest park health tourism suitability is constructed. The analytic hierarchy process (AHP) is utilized for quantitative and qualitative analyses. The results indicate that: (1) The factors influencing the ecological tourism development of national forest parks are ranked as follows, resource value (0.3245), environmental quality (0.3063), infrastructure construction (0.2036), and forest quality (0.1656), among which resource value has the highest weight, making it the critical factor in evaluating the development of national forest park health tourism; (2) Among the 11 selected national forest parks in Jiangxi Province, Wugong Mountain National Forest Park has the highest comprehensive score, while Junfeng Mountain National Forest Park has the lowest; (3) The selected 11 national forest parks can be broadly classified into three types: high-quality, potential, and weak. Based on a comprehensive analysis, this study proposes several development recommendations, including protecting and restoring forest ecosystems, preserving the environmental quality of forest parks, improving infrastructure, and fully leveraging resource value. Health and wellness tourism advancement in national forest parks can be better promoted by tailoring development strategies to local conditions. This approach aims to create a superior living environment, foster urban green culture, enhance urban quality, promote harmony between humans and nature, and further improve the ecological and economic benefits of the forest health and wellness tourism industry.
