Cowan Lake State Park, Ohio

Picturesque inlets adorned with lotus water lilies will transport you to tranquility at Cowan Lake State Park. Study bloodroot and trillium wildflowers as you listen to the coo of herons and pheasants on the resident lake. With a 1,000-ft long beach for waterfront activities and limited horsepower on boats that traverse the waters, this place is sure to keep its cool. Cast a line for the plentiful bounty of fish or hike one of the six trails to choose from—this is your vacation, after all. Bring some looseleaf tea and a pair of chopsticks, and you're ready to go zen.
