Places for picnics can include parks and leas. Parks are large, open areas of land that are often maintained by a local government or organization. They are usually filled with trees, grass, and other vegetation, as well as recreational facilities such as playgrounds, sports fields, and walking paths. Leas are similar to parks, but they are typically smaller and more rural in nature. They are often used for agricultural purposes, such as grazing livestock, but they can also be used for recreational activities such as picnics.
