Royal Park Rajapruek is a massive horticultural park in Chiang Mai, originally established to commemorate the 60th anniversary of King Bhumibol Adulyadej's accession to the throne. The central focal point is the Ho Kham Luang, an ornate royal pavilion built in traditional Lanna architectural style. The grounds span over 200,000 square meters, featuring extensive themed gardens that include collections of rare orchids, international flora, and vertical gardens. The park is subdivided into several zones, including the Thai Garden, International Gardens, and Research and Exhibition sections. The landscape incorporates numerous water features and pathways designed to showcase regional biodiversity. It functions as both a public recreational space and a center for agricultural and botanical research. The park maintains large-scale topiary displays and permanent structures representing different nations' gardening styles.
