Meriden is a showcase for a number of prominent peaks of the Metacomet Ridge, a mountainous trap rock ridgeline that stretches from Long Island Sound to nearly the Vermont border. Notable peaks in Meriden include the Hanging Hills (West Peak, East Peak, South Mountain, and Cathole Mountain); Lamentation Mountain, Chauncey Peak, and Besek Mountain. Castle Craig, a city landmark for over a century, was constructed among the Hanging Hills in Hubbard Park.
