Elm Ridge Park is a 693-acre park located in Rocky Hill, Connecticut. The park offers visitors a variety of outdoor recreational activities, such as hiking, fishing, boating, and picnicking. The park is also home to several points of interest, including the Dinosaur State Park and Arboretum, which features over 200 species of trees and plants, as well as a large collection of dinosaur fossils and footprints.

In addition to the Dinosaur State Park and Arboretum, Elm Ridge Park also features a campground, a swimming pool, and several hiking trails, including the 3.5-mile Cedar Mountain Trail, which offers stunning views of the surrounding area.

One interesting fact about the park is that it was once the site of a Native American encampment, and artifacts from this period can still be found within the park.

The best time of year to visit Elm Ridge Park is during the spring and fall, when the weather is mild and the park's foliage is at its most beautiful. However, the park is open year-round, and visitors can enjoy winter activities such as snowshoeing and cross-country skiing.
