Royal Park Ratchaphruek, Chiang Mai
The Royal Park Ratchaphruek, in Thai อุทยานหลวงราชพฤกษ์ (Uthayan Luang Ratchaphruek), or Royal Park Rajapruek as in Google Maps, is a huge park, mainly for recreation, pleasure and greenery show.
It includes some educational presentations, plates with information e.g. plant names, but is not a botanical garden in the strict sense though it contains quite a lot of different plants. You can spend there a whole day and have not yet seen all. This park is also a site for certain events.
