This is why the trail to Millikin Falls is such a treasure. In a mere 1.6 miles, hikers can visit a waterfall gem while exploring one of Columbus' prettiest metro parks. Even without a water feature, Quarry Trails Metro Park would be a remarkable destination for its ingenious design alone. It also makes Millikin Falls one of the top hiking destinations around Columbus. The most common (and, arguably, best) route to Millikin Falls combines Quarry Trails Metro Park's Connector, Boardwalk, and Flat Rock trails for a scenic jaunt of less than 2 miles.
