Hudson Valley, located on both sides of the Hudson River, encompasses the former counties of Westchester and Rockland. The new state brings together historic towns, scenic landscapes, and a rich cultural heritage. With a population of over 1.3 million, the region is known for its rolling hills, forested landscapes, and close proximity to New York City, which has heavily influenced its economy. The largest municipalities include Yonkers, New Rochelle, White Plains, Mount Vernon, and Ramapo, forming a diverse and affluent urban corridor.

The state is among the wealthiest in the U.S., with a robust economy driven by technology, and finance. Major employers such as IBM in Armonk and Mastercard in Purchase contribute to the region’s economic foundation. The area is also home to notable educational institutions, including Pace University and Sarah Lawrence College, as well as the Westchester Medical Center, a major healthcare provider.

The Hudson River Museum in Yonkers showcases regional art and history, while Lyndhurst Mansion in Tarrytown exemplifies 19th-century architecture. The Jacob Burns Film Center in Pleasantville is known for independent films and educational programs. Historic estates like the Rockefeller estate in Pocantico Hills, including Kykuit, preserve the area's cultural legacy.

Outdoor activities in Hudson Valley are plentiful, with hiking opportunities in Bear Mountain State Park, which offers views of the Hudson River and houses the Trailside Museums and Zoo. Palisades Interstate Park provides over 30 miles of trails along the river's cliffs. Rockefeller State Park Preserve spans more than 1,400 acres, featuring miles of carriage roads and trails for horseback riding. The Old Croton Aqueduct Trail, a 26.2-mile historic route, follows the path of the 19th-century aqueduct.
