We were the only visitors at the time we were there - I imagine because it is the off season and we went during the week. So we had the entire place to ourselves and could stroll around at our own pace. Admittance fees are modest. Apparently you can have a guided tour and there is also a restaurant for lunch. This is a popular place to hold a wedding and we saw tents being taken down from a recent one. The venue is beautiful of course.
We didn’t go on all the trails because some were not suited to our footwear. Perhaps we’ll visit again and see what we missed the first time. So many species of plants/trees and everything is marked with it’s name. Highly recommend these gardens - gorgeous.
