Howell Farm is open for free outdoor programs and tours, but all guests are required to stop at the Visitor Center to register and receive program and safety information. Visitors are encouraged to pre-register through the Mercer County CommunityPass portal

to minimize wait time and guarantee entry to programs with limited admission.

All Mercer County Park Commission rules and regulations are in effect, as well as New Jersey state requirements regarding the use of masks when social distancing isn't possible. Please also note that dogs (other than assistance dogs) are not permitted at Howell Farm, and that picnicking is not allowed at this time.
