Boonville is one of the more popular access points on the Katy Trail, the longest developed rail-trail in the United States at roughly 240 miles. The restored Missouri-Kansas-Texas (MKT) depot in town serves as the trailhead, with information, restrooms, water, and bike-rack parking. From here the trail crosses the Missouri River on a converted truss bridge — a long, exposed crossing with big views of the river bluff and the limestone cliffs upstream.
Cycling east toward Rocheport and Columbia is the classic ride, with limestone bluffs, river views, and a string of small wineries and bluff-side villages over about 30 miles. The trail is flat, hard-packed crushed limestone, and almost entirely car-free. Bike rental is available in town.
