River Trail Loop is a 5.7 mile moderately trafficked loop trail located near North Branch, MN that features a river and is good for all skill levels. The trail offers a number of activity options and is accessible from April until December. Dogs are also able to use this trail but must be kept on leash.

the trails are nicely maintained and it's a beautiful area, but the trails are very poorly labeled!
There is good prairie hiking here with woodland and riverside trails too. Backpack-in camp would be nice though I have only done drive-in camping here. My favorite use of the park has been to rent horses and go for rides in the park (though the stable I used to do this with appears to only board horses now).
Very well maintained, if you are looking for prairie or hardwood forest hiking, then this is a great place.
