For nearly 5 miles, the Columbia Bottom Trail meanders through the Columbia Bottom Conservation Area, which features forests, wetlands and open fields.
The trail is part of the Missouri River Greenway, which will one day follow the river for 50 miles from its junction with the Mississippi River to the western edge of St. Louis County. See the confluence of these two mighty rivers from an observation deck at the trail's eastern end near the Missouri/Illinois border.
Parking and Trail Access
From I-270, take the Riverview Drive exit and go north for about 2.5 miles to reach the Columbia Bottom Conservation Area. Riverview Drive becomes Columbia Bottom Road; several parking areas with access to the trail are available along this road.
