This is a really nice place to walk through during the warmer months. Most of the roses themselves are out in the open, but there is good shade on one side of the gardens. There is a short walking trail with some benches to just stop and relax. It would be a really great place to take a picnic and just enjoy the flora.
It's not really much of an attraction. The museum is cool, the flowers are pretty, but if you are going with kids, they will be very bored. But on a good note, it is a great place to have weddings and take pictures.
