Granville Gorge follows Munn Brook near Southwick, Massachusetts. Town conservation records document management of the area, so it should not be described as an unregulated swimming spot.
A suitable current swimming entry has not been verified. Southwick's 2019 open-space plan reports that former deeper pools filled after removal of Winchell Dam. That historical account is not a measurement of present depth, and older swimming descriptions should not guide entry or diving.
Check current access, parking, facilities and posted restrictions with the Southwick Conservation Commission, 413-569-6907. Its College Highway office is not the gorge entrance. Respect property boundaries and avoid slippery ledges or entering water of uncertain depth and flow.
Confirm the gorge entrance and parking with the Southwick Conservation Commission before travelling. The Commission's office at 454 College Highway is not the gorge entrance. Earlier directions to a first soaking pool have not been verified as a current legal water-entry route.
Contact the Southwick Conservation Commission for the current entrance, parking and posted rules. Historical swimming descriptions do not establish present swimming permission or a suitable water entry.
Confirm the entrance, parking arrangements, and legal access with the land manager. A map pin does not establish a public right of access. Follow posted routes and never block gates or driveways.
Current swimming permission has not been independently confirmed for this listing. Check official rules, fees, hours, and closures before visiting. Public park access does not necessarily include permission to swim. Respect private property and posted restrictions.
Water conditions can change quickly. This listing does not provide a current safety or water-quality assessment. Check official alerts and avoid entering water when conditions or permission are uncertain.
Nearby places from saved public map data, not necessarily facilities at the swimming spot. Confirm access, hours, fees, and amenities with the operator before you drive.
