We visited the end of September. The Conservatory is beautiful, lots of lush plants and a cute waterfall and pond at one end with a bench, perfect for taking a short break. When we visited they were having an orchid exhibit with plants you could purchase. The Sunken Garden was disappointing because the fountains were 'being maintained', apparently for the entire season. There was great fall color in the park however so we got good pictures. We plan to go back in the spring to take graduation pictures. One negative, the bathroom, there's only one and it's small and gross. Plan to go before you arrive or wait until after.
