The Grist Mill Covered Bridge, which is also known as the Scott Covered Bridge, the Bryant Covered Bridge, or the Canyon Covered Bridge, spans the Brewster River near the beautiful Brewster River Gorge and falls. This bridge is one of a small number of surviving Burr arch truss bridges in the state and was built in the 19th century. In 1974 it was listed on the National Register of Historic Places. There is a nice overlook for the Brewster Falls not far from here, down a short trail if you wanted to leave your bikes and go on a short walk.

The West Farm Trail is located within the Brewster Uplands and loops through the woods northeast of the gorge, past farmlands that are still in use. There are several trails that connect to The Alden Bryan Trail, which parallels the river, and the Brewster Pond Loop, allowing you to lengthen your hike if you choose. Please note that two farms and associated fields on the property are not open to public recreation; they are working farms so please be respectful as you hike around here.
