Rocky Hill is a commercial center, and along with attractions like Dinosaur State Park and the nation's oldest ferry line, make it a popular New England tourist destination.

Any great civilization would say the secret to success is easy access to a river, and the town of Rocky Hill is no exception. East of the Connecticut River, the waterway made Rocky Hill an active maritime center during the age of sail. As steam replaced sail, Rocky Hill's role as a river port diminished. Farms grew, and the town became a thriving agricultural center. In recent years, Rocky Hill has become a residential community. Modern highways and a central location have contributed to the town's growth and made it a commercial center, along with attractions like Dinosaur State Park and the nation's oldest ferry line making it a popular New England tourist destination as well.
