Which park in New Orleans is known for its historic plantations and large recreational area?

City Park is recognized for its expansive recreational area and the historic plantations that are part of it. It encompasses over 1,300 acres, making it one of the largest urban parks in the United States. City Park features beautiful gardens, walking and biking trails, playgrounds, and a variety of recreational facilities, including a lake for paddle boating and expansive green spaces ideal for picnicking and outdoor activities.

Moreover, within City Park, visitors can explore the historic architecture of the park, including structures that showcase the city's cultural heritage. The park's blend of natural beauty and historical significance attracts both locals and tourists, making it a standout destination in New Orleans.

Other parks mentioned do not offer the same combination of historic plantations and extensive recreational activities. Audubon Park, while beautiful and notable, primarily emphasizes its natural landscapes and does not feature plantations. Riverview Park and Milneberg are much smaller in size and do not have the same historical significance tied to plantations. Thus, City Park stands out as the correct choice for this question.
