Longwood Gardens at 1001 Longwood Rd, Kennett Square, Pennsylvania.

Beautiful gardens!! We went in the winter, and cannot wait to visit again when it is warmer and more flowers are in bloom. It is fairly reasonably priced, though the cafe is on the pricier end. There are tree houses that kids and adults love! Lots of fun activities and room to run. We visited with a 4 year old and 18 month old with no issues - they loved seeing all the different flowers and playing at the tree houses. We will definitely return!
