Iowa Water Trail · Cedar River Greenbelt

Iowa's longest interior river stretches 300 miles through the agricultural heartland, passing through Cedar Falls, Waterloo, and Cedar Rapids. Broad riffles, wooded islands, and surprisingly diverse fisheries make the Cedar a year-round paddling destination and one of Iowa's most accessible water trails.

Data Quality

River conditions are community-verified. CFS ranges, difficulty ratings, and trip sections may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level. If you spot an error, use the Improve This River button at the top of the page — your local knowledge is what makes this atlas accurate.
