10 miles ONE-WAY to Chain of Rocks Bridge, and 1 mile over bridge. Return on Missouri side or on the eastern side of the river, using the Levee Rd. or Madison County Confluence Trail along Chain of Rocks Canal
About 1 mile northeast of the Gateway Arch and right near the Four Seasons Hotel is the start of the St. Louis Riverfront Trail. This is a bike path that goes for 11 miles to the Chain of Rocks Bridge, which is a pedestrian crossing over the river to the Illinois side. It is possible to loop all the way back to St. Louis on the eastern side of the river, using the Levee Road or Madison County Confluence Trail paths on either side of the Chain of Rocks Canal. Some parts of the path are great — and is a treat to run across the Chain of Rocks Bridge — while some other sections of the path, to put it one way, embrace some of the river’s historical and industrial past.
