The State launch ramps at the Huron river, in Huron, on the east side of the river, Route 6 (Cleveland road East), are very nice. Several ramps, wide, and lots of parking for vehicles and trailers. Quick out to the Lake.

A little farther east is Cranberry Creek Marina, also on Route 6. Small place with very small launch ramp, decent parking area, but very easy 2-3 minutes to Lake. Bait and tackle and food / beverages.
