The Gardens are quite beautiful - Especially during the spring. The grounds are immaculately maintained, and the staff is very helpful......
The prices, though.....My goodness! $18 for an adult.....Seriously? The garden is nice, but yikes! After a couple of hours and a few photos, I was done.
They do have a cafe with packaged sandwiches, salads, etc, but once again, prices are high.
Stay away in the summer unless you want heatstroke - BRIING YOUR OWN WATER so you don't have to buy theirs! Springtime is best, and be sure to get get a home equity loan before you arrive!
