While the trails at Newlin Grist Mill remain accessible while the site is closed due to the COVID-19 pandemic, we do want to remind everyone of a few things:

  • Continue to observe proper social distancing when you are on the trails. If you are ill or have been around anyone who is ill or has been exposed to the virus, please remain at home. If you arrive and find that the parking lot is crowded, please postpone your visit to another time.  

  • Please remember that all dogs must be on a leash that is held securely by the owner at all times. This is a township law, and it is to protect the health and safety of all park visitors (human and canine) and the wildlife in the park.

  • The park contains unique habitats that are home to sensitive plants and animals, some of which are being monitored through ongoing scientific surveys.  Please stay on the trails to avoid disturbances (wading, dip netting, collecting, rock throwing etc.) that could damage wildlife and vegetation. 

  • Remember that collecting of any kind, including plants and animals, is prohibited in the park.

We appreciate your understanding and support during this challenging time.
