Weir Farm National Historic Site in Connecticut is a small NPS site commemorating the fusion of art and nature. The site preserves the home of American impressionist J. Alden Weir. Take a walk around the grounds and view Weir Pond you may catch an artist painting the scene.
In addition to the house and grounds there is an adjacent 110 acre network of trails called the Weir Preserve. If you have young children be sure to do the junior ranger program. The activities for the badge include a scavenger hunt through the grounds, great fun.
Art is a big part of the park and not only are there artists in residence but there are art supplies available so you can try your hand at your own artistic endeavors.
