The Holyoke Range or Mount Holyoke Range is a traprock mountain range located in the Connecticut River Valley of Massachusetts. It is a subrange of the narrow, linear Metacomet Ridge that extends from Long Island Sound near New Haven, Connecticut, north through the Connecticut River Valley of Massachusetts to the Vermont border. It is also a subrange of the Appalachian Mountains. A popular hiking destination, the range is known for its anomalous east–west orientation, high ledges and its scenic character. It is also notable for its unique microclimate ecosystems and rare plant communities, as well as significant historic sites, such as the Mount Holyoke Summit House and the Horse Caves.[1][2]
