Three major streams in the area converge into one, providing year round water, and the regional climate in this mountainous area is ideally suited to the project. In the early years, Queen Sirikit Botanical Garden was visited by directors and administrators from renowned botanical gardens around the world who unanimously gave their support to the project and over the years it has developed into a truly world class establishment. The center does not just provide botanical study and research facilities but also provides a place for relaxation where visitors are welcome to enjoy the beauty of Thai flora.
