The Welwyn Preserve in Glen Cove, New York is the home of the former Pratt family mansions. While the actual mansion is now the site of a museum, those that take a hike through the grounds via the Welwyn Preserve County Park Loop can find some of the family’s old greenhouses, which are run down and full of graffiti. There’s something cool and a little bit creepy about these greenhouses, though, and they are a good reason to take a hike around the grounds. For more information about this interesting hike, which contains some of the best abandoned greenhouses in New York, keep reading, below.

Welwyn Preserve is located in Glen Cove, New York, which is around 30 miles away from New York City.

To find the greenhouses, all visitors have to do is park at the preserve and take a trail that is located on the right side of the mansion. After a period, hikers will notice a brick path that heads straight toward the greenhouse. There is even a beach on-site that visitors can walk to, as well!

The trail is a 2.4 mile loop and considered by most to be a very easy route, so it makes for a great hike for families, both young and old.
