Rockefeller State Park Preserve is an idyllic spot for strolling, jogging, horseback riding, cross country skiing, and snowshoeing. With 180 recorded species of birds and its IBA (Important Bird Area) designation by the National Audubon Society, the Preserve is a must visit area for birders. In season, licensed anglers enjoy fishing for bass in the 22 acre Swan Lake and for brown trout in the Pocantico River. In addition the beauty of the Preserve inspires many artists and photographers to memorialize its scenic vistas. While in the park, stop in the Preserve's Gallery across from the Visitor Center. Its rotating exhibits feature the art of local artists. Within walking distance are the Preserve's nearest neighbors - The Stone Barns Center for Food and Agriculture, a nonprofit farm and educational center designed to demonstrate, teach and promote sustainable, community-based food production and Blue Hill restaurant.

This is a great place to walk with kids. It is beautiful and stroller friendly, as long as you have a stroller that can go on non paved paths. There are great paths and the map is easy to read. There is a beautiful lake in the park, and there are turtles and ducks. Also, you are allowed to walk off the preserve onto a farm, as long as you stay on the paths. I took my daughter here in our stroller almost every day of summer when she was an infant, and now that she is a toddler we still love it. She can walk along beside me now. Just make sure to bring a lot of water and comfortable shoes.
