Covid-19 Update: NYS Parks now advises that we may begin a cautious resumption of safely controlled walks and tours. We will begin to offer open-air walks and tours involving small groups, with masks and proper social distancing required. Participation will be by reservation only. Notices of any such walks and tours will appear on our website, Facebook, Instagram and in our eBlasts.
The Keepers House is still closed until further notice. Maps of the Westchester and New York City portions of the trail are available for purchase here. Retail locations also are listed here. Of course, the Aqueduct trail is still available for personal use and enjoyment, consistent with whatever the current health advisories are at the time. We are especially lucky to have the trail readily at foot during this time.
