While less-known than popular destinations such as Cape Cod and the Berkshires, the Valley region of western and central Massachusetts is home to a wealth of natural areas, picturesque countryside, abundant wildlife, and historic sites connected by the watersheds of some of New England's most scenic rivers. Among the areas featured are the Deerfield River and Mohawk Trail, the National Wild and Scenic Westfield River, Quabbin Reservoir, southern New England's largest conservation area, the North Quabbin Bioreserve, and the Connecticut River, one of America's most celebrated waterways. In addition to its diverse natural features, the region boasts a rich human history that includes the construction of the Hoosac Tunnel and Keystone Arches Railroad Bridges, the discovery of dinosaur tracks in the Connecticut Valley, King Philip's War, Shay's Rebellion, the great storms and floods of the 1930s, and the controversial creation of Quabbin and Wachusett Reservoirs.
