Chesterfield Gorge Fishing Access Site provides access to the Westfield River's East Branch, a designated National Wild and Scenic River, with catch-and-release fishing permitted using artificial lures only.

The site features a dramatic natural gorge with 70-foot granite cliffs and offers hiking trails along the river; parking is available ($5 for non-residents) though the lot is not plowed in winter.

Access to the river through the gorge itself is prohibited due to dangerous water conditions, but the site connects to the 9-mile East Branch Trail for paddling and fishing opportunities downstream toward Knightville Dam.
