The asphalt is beat up from tree roots, lots of debris on the paths, low hanging tree limbs, messes from homeless people. Signs missing to tell you where to turn making it hard to follow trail.
Has lots of potential, and could be an excellent path if maintained.

Starting from the Tower Park Trail head this path is a very easy 7 mile loop. M-91 was the only road crossing that was a challenge with higher speed heavy traffic. All other road crossing were light travel neighborhood streets.
The trail follows the river for the first half of the loop and you will cross M-57 and M-91 for the second time on trail under the road bridge.
The second half of the trail follow the roadway around the Greenville schools and a tunnel allows passage back under M-57.
A mile or so later you descend down a long hill to the beach at Baldwin Lake. When you reach the beach turn left and follow the lake front road. A left turn at Makoka lake road (just before crossing the small concrete bridge) will lead you back to the starting point, a loop of about 7.5 miles. Baldwin lake road circles the entire lake adding a couple of very enjoyable miles.
Overall the trail was great, in the shade most of the first half. I love that you can circle back to the start point almost all the way on trail.

nice, 12 foot wide fully paved path which goes through soybean and corn fields. almost all of it in the full sun. not too many riders. your only option to buy cold drinks is at a tiny convenience store in Conklin. your only option for food is at the Ravenna bar which has good food. Plenty of parking at the various parking lots such as Muskegon, Ravenna, and Marne. If you break down or have an accident there are so few riders that you might be out of luck. I imagine that this trail would be very beautiful on a late summer or early fall day when the leaves are turning.

I headed north from Parchment about 4 miles. The trail has a lot of sticks on it which caused me to stumble a few times and then has a lot of hills that don’t seem terrible going up, but are awful going down. I had to abort by running off the trail and into a bush lest I trip over the railroad tracks at the bottom and shatter every bone in my body. Maybe it’s better heading the opposite direction?

Rode 20 miles roundtrip north from Big Rapids. Much of the trail is very rough and bumpy. I rode this section two years ago and it has clearly gotten worse. It is apparent that snowmobiles are causing damage as the worst of the pavement is found in open areas that get more sun. It is a very pretty section of trail with views of the river and a lot of deer in the fields. I hope DNR decides to invest in this trail's maintenance before it becomes unrideable for road bikes.

Wow! Recently updated and paved. Such a great scenic route north. Walked 8 miles and so much wildlife and amazing scenery. Park at Creekside Park and walk a few minutes to the trail head.

Trail is a bit bumpy, with very little tree canopy for relief from the sun. Not as scenic as some trails. I’d probably ride it more in the Fall or Spring when you want sun for warmth. Summer is pretty brutal, not a lot of shaded areas.

The trail has many, many roots creating bumps in the asphalt. Additionally, especially on the western leg there are a lot of dips and gaps in the paving. Also while there are a number of trail maps along the way, the ones I looked at didn't have a "You are here" marker. Had I known about its poor condition, I wouldn't have driven out 2 hours to ride this trail.

Short connecting trail between Valhalla trail and the Lansing River trail. Good quality road, a wooden bridge to go under the highway, and several sharper turns. It’s hard to determine where you turn to continue on the Lansing River Trail from the Sycamore trail (pro tip: cross the street to start the Lansing river trail in Maguire park).
