Yucky trial. We rode from Springfield out to South Bend. Deep gravel that was unsafe to ride on and lots of dog poop. We will not be back.

After starting from the Lewis and Clark National Historic Headquarters and Visitor Center, we bicycled across the awesome Bob Kerrey Pedestrian Bridge, rode the Iowa Riverfront Trail, and then crossed back to ride the Omaha Riverfront Trail.
I'm sorry to say it was less than impressive. We traveled from Southern California to experience the bridge and bike trails on both sides of the Old Muddy, and Omaha really let us down. There were some great views of the Bob Kerrey Pedestrian Bridge and the mighty Missouri River, but due to construction the downriver portion of the trail past the Lewis and Clark center was closed off!
Heading upriver was just as disappointing. After a mile or so the trail just comes to an end at a restaurant parking lot. We were tempted to ride through the parking lot, get on Abbott Drive to find where the trail eventually resumes, but these two senior citizens didn't particularly want to share the road with two ton vehicles whizzing past us.
OMAHA: We look forward to coming back when all of three sections of your Riverfront Trail are a connected Class IV Bikeway and construction free!

The wife and I thoroughly enjoyed our trip bicycling from the Nebraska side to Iowa and eventually back over on this awesome suspension bridge in October. Plenty of photo ops, pedestrians, and joggers!
Bicyclists: Plan on riding Omaha's Riverfront Trail and Iowa's Riverfront Trail on either side of the bridge to make a day of it! Council Bluff's Tom Hanafan River's Edge Park is especially cool with its large grassy areas, trees, and sculptures!

On a glorious Sunday morn in early October, my wife and I crossed the Bob Kerrey Pedestrian Bridge from Omaha into Council Bluffs to experience the Iowa Riverfront Trail.
On a vacation from Southern California to ride our bikes in ten states, I'm sorry to report that this trail was nothing to write home about.
In all fairness, the bridge is awesome, the Tom Hanafan River's Edge Park and amphitheater area with it's large grass area, trees and sculptures is pretty cool, and there are some awesome views of Old Muddy and the downtown Omaha skyline, but that's about it for highlights. As soon as you start riding in either direction from the bridge, it becomes somewhat disappointing.
After ignoring the temporary "Keep Off the Trail" sign and barrier , we headed upriver. It was OK with some pleasant Omaha views, but felt a bit sketchy when entering a woodsy area with obvious remnants of some homeless camping. Try to ignore the speeding cars racing by on the freeway.
Going downriver from the bridge was discouraging too. It's not especially picturesque, but you do get to ride through the parking lots of a couple of casinos!
I will concede that at least this is a great, well maintained, flat trail for the locals to work out on.

Enjoyable tree canopy trail that travels through western Iowa’s farmlands and small towns. Should be on everyone’s trail adventures list. We will definitely be back for another ride.

Beautiful tree canopy trail passing through western Iowa farm land and small towns. We can’t wait to come back and enjoy the trail again next year! Should be on everyone’s trail list.

Nice trail all cement hopefully they extend it before long support your local trails

The first eight or nine miles is fine except for finding large, very large grave(Gravel that will never break down unless semi’s drive over it, for years). These sections that are very uncomfortable to ride over. Then you get to the corn and soybean fields, do not go this way unless you like pushing your bike through soft sand and more of the large gravel chunks. Then you head towards Peru and the Trail is growing in nicely with weeds in the middle and you get to Peru hoping for a nice rest stop and someone has vandalized the bathrooms and it looks like it’s been that way a long time and you cannot go past this point towards Brownsville, barriers all over for that way. But the first 9 miles was very nice.

Road the tail to Peru back on hybrid bikes. First 6 miles is in the trees and great shape. The next 5 miles to Peru, the trail had rough spots and areas of loose sand and gravel but doable. The bathrooms at Peru are not working. Overall, great trail with no traffic.
