Griswold is a community dotted with rivers and lakes and contains many beautiful hills and small mountains. The two rivers that flow through the town are the Pachaug and the Quinebaug.
The Borough of Jewett City is situated at the junction of the two rivers. From the hills which border it, the Griswold basin presents delightful landscapes. There are points from the roads across Stone Hill where the north end of the valley to Jewett City spreads out in lovely vistas.
