The Great River trail (GCC Ride #4) was the first trail in the Quad Cities. This is a nice paved trail that runs next to the Mississippi River the whole way.
Duck Creek Trail was (GCC Ride #5) was the second trail in the Quad Cities. Another Paved trail and starting at the west side and riding east it is mostly down hill.
The Heritage Trail: Dubuque to Dyersville (GCC Ride #6) was paved on the Dubuque side but once you get out of town it is crushed limestone. Still a very beautiful trail. This is a Fee trail ($2 Daily Pass). It can be paid at the trail head or online @ Heritage Trail Pass For 2022 registration information at GetMeRegistered.com
