We rode the 26 +/- mile route in mid July 2019.... Very nicely maintained trail and quite well marked. Mostly level with a few grades, nothing major. Wind was a nuisance the day we rode, but still a great experience.

Was so surprised at how nice this trail system is; well maintained and laid out! Many cities should use this as a model for what should be!

Love our trail system. Ride it regularly! Pick you direction carefully so as to not have to ride UP the spillway ;-)

On my way to the black hills I stayed at one of the hotels near I-29 and just biked on the sidewalk a few blocks east to the loop. The 21 mile loop is all paved and smooth, and very scenic while along the rivers. The north section of the loop around the airport is on the top of a levy and kind of dull, but is flat and smooth so you can get a good workout if desired.
There is a good bike map on the city website.

We came to Sioux Falls specifically to ride the trails and they were absolutely delightful. There's a nice mix of urban and suburban cycling here. It's possible to get just about everywhere by bike. Many intersections include wide, well lit underpasses. Solid system. Five stars.

The city of Sioux Falls has created a wonderful biking experience for its residents and visitors!We road in October 2018 and could not have more pleased with the ever changing scenery and smooth trail surface.Road bikes work the entire 26 miles with very few cross roads to contend with.The trail passes through several city parks and South Dakotans enjoy the outdoors!Sioux Falls has many interesting restaurants and Airbnbs to add enjoyment to your visit.

We rode the entire loop last October and it was fantastic! So many cool things along the way including the spectacular falls park. Highly recommend!

We rode the entire loop today and this is an exceptional trail. It winds through park after park with smooth, wide lanes.

We rode several miles from Sertoma Park going south and east. These are a wonderful resource.
