Biking the Old Putnam rail trail which starts in Van Cortlandt Park, The Bronx, NYC in mid October 2024 -- it takes a short trip through Tibbetts Brook park and mostly follows the path of the Saw Mill River.

The trail whose name switches from 'Old Putnam Trail' to 'South County Trail' at the boundary of The Bronx and Yonkers, winds parallel to the I-87 interstate and Saw Mill River Parkways, but mostly has enough buffer of a forest so that these roads are not visible. There are nearly no road crossings. One of the best rides out of NYC and suitable for kids. This trail is extremely easy to access in NYC beginning near the Bronx terminus of the 1-train.

This trip is little before peak fall foliage (but in a dry year, which means less vivid colors than typical). This clip turns around in Ardsley, after ~12 miles, where engineers are removing a dam from the Saw Mill River.
