Located on the side of the church of San Domingo, the area is not very large, basically the same area as the church, basically tropical plants inside, mainly a variety of cactus. You can accompany the tour guide with explanation, but there are not many English groups, and the meaning is not great if the English is not very good. If you are not particularly interested in plants, you must observe it up close or English and Spanish are good enough to understand the explanation of the tour guide, otherwise it is not recommended to visit the botanical garden. It is recommended to buy tickets for the museum next to the church, in addition to visiting the museum, you can have a sweeping view of the botanical garden in the corridor on the second floor, and it will not be exposed to the sun.
