Grass Island Dog Park in Greenwich, Connecticut has separate areas for small and large dogs. It is on a grassy hill near the water, which offers nice views. However, it is close to a waste treatment plant, so there can be bad smells sometimes. The park has basic facilities like parking and portable restrooms. Visitors should bring their own water because the only water source is outside the park.
