I am sure there are virtually no negative reviews of the garden. It is a great place to spend a few hours. It will both delight the visual senses and add a few things to your knowledge base. The staff can answer almost any question you may have and will also add some very interesting facts about the many, many unusual plants that abound. I did not visit at night, when the place is lit up from the top of the mountain to the base. That would be a whole different adventure. Cannot go wrong with the garden.
