Initially, the Hank Aaron Trail ran slightly downhill through older neighborhoods on the outskirts of town, past single family post-war homes visible through the trees. It was a tree-lined, single car-lane sized concrete trail, meaning there was room for two bikes across, but not three. We were warned by another biker not to miss a sharp left turn ahead, which we found (following him) as we neared the very cool American Family Insurance Stadium.
Continuing towards the waterfront, the trail became a wide sidewalk alongside a fairly quiet industrial avenue lined with unused railroad boxcars. Beyond them was an active railroad yard and tracks that we crossed as the Milwaukee skyline came into view. Nearing downtown and the beginning of several waterways where small pleasure boats were moored, we passed the Harley Davidson Museum.
Signage got very spotty as the route became more complicated and we had to refer to TrailLink a couple of times after we crossed over the downtown river. We ended up riding on the city streets and sidewalks of the Historic Third Ward area. At that point, we abandoned trying to follow the trail (it ended somewhere nearby) and headed toward a descending drawbridge over a canal lined with sailboats.
While a large network of walking/biking paths crisscrossed the entire area, we rode close to the rocky revetments and corrugated iron seawalls that kept the Lake at bay. There appeared to be lots to see and do on the Lakefront: we passed an outdoor amphitheater, a small red lighthouse, other performing venues, a building designed to look like a large ship’s prow (Milwaukee Art Museum), Discovery World science and technology center, and more. The promenade eventually ended on a long, wide jetty, beyond which was McKinley Marina.
We found good beer and award-winning fried cheese curds at a brewery/restaurant north of downtown.

Very short trail, it does connect to the big bend muskego trail

We started this trail out at merton firemans park, and went east to the falls, trail is all paved, beautiful scenery, goes under 164, nice woods, great view of the quarry, great ride

Was very excited to try this trail between Fish Hatchery (Delafield) and Oconomowoc downtown....but was disappointed. So much of the trail is between power line poles and fairly uninteresting. The worst, however, was the stretch around Nemahbin Lake--where the trail literally disappears completely and you are left navigating a narrow, heavily travelled road with no shoulders in some places! I can't believe this portion is still called the Lake Country trail--when there is no trail. I would not recommend this route for families with young children, given this dangerous stretch with cars whizzing past.

...loved the concept of this path and the ability to enjoy downtown Delafield and downtown Oconomowoc, though. I just wish is was better developed and a bit more interesting/rustic.

I think the Kinnickinnic River Trail is a good riding trail. You can see lots of nature on the lower portion of the trail (south of Lincoln Ave). The upper portion runs along the railroad tracks which is separated by a chain link fence for safety reasons. Amtrak rolls by about every few hours. The day I rode it (Sunday afternoon in early Oct), the trail wasn't very busy. Probably due to Sunday afternoon football games.

The only bad part of the trail is that you have to ride the road for 0.7 miles to get to the lower portion. The good part about the road is that it isn't very busy and it does have bike lanes.

Really really liked the trail, I’m in town from Michigan for work and what an awesome way to spend the day. I’ve never road gravel before today and had a blast

It’s right in our backyard and we have been on every portion with e bikes. LOVE it all. See wildlife every time. Also hike in winter months

Picked up trail on Hwy K in Cedar Grove and took it to Kohler-Andre Park. Trails are nicely maintained, restrooms along the way. At Oostburg you are on country road the remainder of the way. Little to no traffic. Also, not very scenic. Kohler-Andre is great.

Beautiful trail between Lake Mills and Deerfield. Ice cream in Deerfield! No ruts - hard packed crushed limestone. I rode my road bike with out problem. Just wish they had ice
