Ride along on the 6,500-mile Great Lakes Circle Tour: a scenic, international road system connecting the five Great Lakes and the St. Lawrence River. Take a journey across Ohio's lakeshore. Discover sights and places you've never seen before, such as windswept prairies, rare alvar, neotropical songbirds, abandoned sand dunes, majestic lighthouses, towering oaks, ocean-dwelling plants, rocky ravines, working canal boats, and lush river valleys. Look no further than Ohio for repelling down majestic bluffs, angling for a champion-sized catch, biking along the more than 500 miles of designated paths and canoeing on Ohio's scenic rivers.
