Kettletown State Park in Southbury sits on the shore of Lake Zoar along the Housatonic River, with wooded hills sloping down to the water. The park has a quiet, secluded feel and is a good escape from nearby towns. Visitors can swim, fish and walk trails that lead through the forest and along the shoreline. The area has a long Native American history, and the park's name and setting recall the people who lived and traveled along the river. Camping is available for those who want to stay longer. Entry is free on weekdays, and weekend parking costs $15 for Connecticut vehicles and $22 for out-of-state vehicles. It is a good pick for a low-key day by the water.
