The Mad River is Ohio's largest and most prolific coldwater fishery and one of the best places in the state to paddle. The roughly 60-mile waterway is fed by springs, never reaches 70 degrees and flows through a good cross-section of western Ohio countryside.

Two liveries operate along the way: Aaron's Canoe and Kayak Center in Springfield and Birch Bark Canoe Livery in Urbana. Both offer canoe and kayak rentals, transportation for those with their own boats and knowledgeable river experience.

Here's more about a trip through the southern section.
