We start and end in an urban park – but in between, expect Sing Sing village tales, close Hudson River views from a nature reserve, a stroll through the rocky gorge of Sing Sing Kill, a hidden museum and a neat microbrewery … all of it near or on the Old Croton Aqueduct Trail. If you’ve seen BlackkKlansman, you know this turf! Some hills, 4 miles, 3 hours (excluding brews). Wear hiking boots and bring water, snacks. This outing is for people who walk fairly regularly. Heavy snow cancels. Meet inside Ossining’s Nelson Park, which borders Route 9, on the S.
