In reading reviews of this garden prior to going, I wasn't sure it would be worth the visit in terms of what we would see and all of the walking. It looks enormously overwhelming on the map. However, I am pleased to report that my wife and I spent 5 hours here and loved every minute of it!!! The walking was not excessive and the gardens flow nicely into each other and are actually much closer to each other than it would appear on the map. To give you some perspective, I am 60 and she is 54. We are in good health and bike occasionally, but we are not what you would call "fit" or "athletic." Just average. Every garden had something to offer and was fully in bloom when we went on August 9th. I'm not sure what the person who said there wasn't much to see was looking at, but we found SO much to see that we couldn't take it all in. We didn't take advantage of the free shuttle that gives an overview of the gardens, but I can imagine this would be great as well, especially if you are concerned that you might not be up for all of the walking. One particularly nice, unexpected surprise was a 30 minute cooking demonstration at an outdoor kitchen by an indigenous chef that included a tasting for everyone of what he cooked. We also ate lunch at the restaurant which has lovely outdoor seating. We were a little surprised that it was a cafeteria style restaurant (I'd really call it a cafe more than a restaurant), but were pleasantly surprised as the quality of the food. I had half of a falafel sandwich and half of an egg salad sandwich, and my wife had a grilled cheese and potato salad. Honestly, the falafel sandwich was one of the best I've ever had (and MUCH better than the falafel tacos I had at our hotel's fancy (and expensive) rooftop terrace). So, our 5 hours did include the cooking demo and lunch, and we actually didn't see everything. There was probably another half hour or so that we didn't see, but our feet were done by that point. One poster said she wished the guides had been in English. Here's a tip - if there are no English guides at the ticket booth (which there weren't when we were there), check the visitor center next to it (where the restrooms are) - there were plenty on a rack in there. Also, if restrooms are a concern, there were plenty around the park, for example in the Chinese garden, the restaurant, the visitor center, etc. We had no problem finding one when we needed it. Also, on the map, the parking looks small and far away. It is neither - plenty of parking and it's not far from the ticket booth.
