A Message from the Park Sr. Naturalist, Kirk Dreier & the Cromwell Valley Park Council

Cromwell Valley Park is open for public visitation 7 days a week from sunrise to sunset.
In order to enhance Park security, the gates at Willow Grove Farm and Sherwood Farm are closed each evening at sunset and re-opened at sunrise. All CVP visitors should make sure that they leave the Park before the gates are closed. Vehicles in the Park after sunset may be locked in overnight. Any persons in the Park after sunset may also be charged with trespassing. Everyone’s co-operation with this procedure will ensure that CVP remains a safe and secure place for everyone to enjoy.
