Nice view of the Tarrytown Reservoir. The trail runs very close to the water, so you have a wonderful, unobstructed view across the reservoir. The path is popular with cyclists, so make sure you move to the edge if you want to stop to enjoy the great vistas.

Painted turtles can be spotted sunbathing on fallen logs near the water's edge. Lily pads and water lilies flourish across the wetland surfaces. Graceful herons stand watch in search of fish. And in winter, migratory waterfowl find respite and rest on the peaceful waters. The biodiversity along Brother's path provides ample wildlife sightings for nature lovers throughout the seasons.

Beautiful lake, at the eastern end there is a kayak rental in summer. A short boat trip loosens up the cycle tour and cools you down.

The climb to the Kensico reservoir on North Kensico Avenue is quite steep. Also, there is typically a lot of traffic on the short stretch of Broadway to get to the climb, so you might want to ride on the sidewalk. There is an alternative car free path on the East side of the Valhalla dam, at the entrance to the Kensico Dam Plaza on the right side.
