I biked the entirety of the improved portion of this trail yesterday 10/9/19.
I started in Ovid, where there was parking by the trail but no public restrooms and headed west. As anticipated, the trail was improved and very nice until Smith Road just west of Owasso (about 7.5 miles). Past Smith Road, the trail was overgrown with grass 2-3 ft tall and trees growing across--impassable without a machete. I turned around there and rode all the way through Saranac, where the trail ended at mile marker 133. Past there, the trail had original railroad ballast with large stones, not passable even with a mountain bike. I then turned back and returned to my car in Ovid. The most beautiful part of the trail was West of Pewamo, as it was along the Grand River valley. East of Pewamo to Owasso, it is primarily farm land sheltered by a line of trees in most places. There is parking and restrooms along the trail in St. Johns, Fowler, Pewamo, Muir, Ionia and Saranac. The trail was beautifully, newly paved asphalt within all of the towns, and hard-packed crushed limestone in between. It was perfect for a cyclocross bike or mountain bike and most likely entirely passable with a road bike (some rare soft spots in the crushed stone could be difficult). I will definitely ride this again. 51.5 miles of improved trail total, for a round tip distance of 103 miles.

We parked at the Trailhead just South of Cadillac. Biked 2 miles into the city of Cadillac for lunch. There's also some great little shops in Cadillac.
Biked from Cadillac to LeRoy and back, approx 35 miles round trip.
Trail is very nicely paved asphalt through open areas and wooded areas.
Great ride on the Northern section of the trail.
Between Cadillac and LeRoy you will pass through Tustin which has a few small stores if you need anything.
Along the trail there are wooded sections of huge white pine trees.

We parked at the Jackson's Landing Trailhead in Greenville. Biked a few miles North on the Heartland Trail. This was after we biked on the Flat River Trail.
The Heartland Trail is newly paved and in very good condtion.
In Greenville there are places to eat and other services.
Hope to do more of this trail in the future.

We parked at Jackson's Landing trailhead. Large paved lot and portable restroom.
Trail is asphalt paved and plastic decking. The plastic decking sections are extensive and very rough and bouncy if traveling at a decent speed.
The trail goes along the Flat River. Coming out of Greenville the trail is more of a paved sidewalk, up near the High School.
Trail services include eateries nearby since most of this trail is within the city limits.
You can also access the Heartland Trail from Jackson's Landing trailhead.

As I am still a beginning cyclist with this being only my 3rd trail, I have come to appreciate the signage and directions each trail posts to help you stay on the right path. We parked at the Chippewa Nature Center & rode into Midland where the Tridge begins. As we came up to town, even though there was a slight detour due to construction on M20, it was well labeled. We rode to Sanford and found some special treats along the way. Looking like a scene from "Bridges of Madison County", I loved the different bridges along the way. At the Veteran's Memorial if you look closely, draped around the boot statue are the dog tags with a solider's picture on it which was such a nice tribute. We stopped at The Cottage Creamery which is accessible from the trail or Saginaw Rd. and tried the Apple Crisp ice cream. We got another treat as we sat on the back deck when the cute little chipmunks playfully ran around waiting for me to drop my ice cream. It is a pretty straight trail, but there is a lot to appreciate on this trail, and it's very bike friendly. I would like to finish the trail and head to Clare from Sanford. Walking or riding, people passing by are very friendly, and if you take a few breaks, there's definitely some awesome photo opportunities. Great Job Pere Marquette!! We'll be back for sure.

My sister talked me into doing the Lansing Riverwalk trail a week ago, and I was hooked for my first time ever riding a bike on a trail. As I impatiently waited for our next trail ride to Bay City, we looked up reviews, and I'm glad we did. Thankfully, we were prepared for the challenges. We parked at Veteran's Memorial Park and headed out from there. As several reviews stated the trail was poorly marked, so our first stop was not far at the ice cream shop where we asked for directions. As we got a little further into an industrial section, a gentleman passing by overheard us question if we were going the right way, so he casually responded, yes you are. After crossing a couple busy intersections with traffic, we rode until we came to the state park, and when the water view emerges, the view is breathtaking and worth the ride. Our view & course changed again when we entered into a forest area. Again, it was breathtaking, even with a few bouts of challenging sand. Once we got back to our starting point, we rode a little further the other way, and discovered a whole new area of beauty on the waterfront. We kept getting an aroma in the air of what smelled like peanut butter, but was informed by some locals it was the sugar beet plant. Overall we rode 25 miles, and for only my 2nd course and a few challenges, I am even more hooked now. The fact that it does not cost a cent, you get to see some really cool things along the way, meet some amazing people, and the memories are priceless make it well worth the adventure. We also decided to start trying new eating spots as well before our ride, so this time we stopped at Mr. Hot Dog in Bay City. Food was awesome and it was actually cheaper than stopping at fast food. Our Lansing ride took us to The People's Kitchen which I gave 5 stars!!! I think if you plan ahead for this one by printing the trail maps and know that you will be going through a variety of terrain & a mixture of city and trails, stay hydrated, and don't get frustrated, you're in for some real treats with the views. I cannot wait to get a few more trails in this fall, and look forward to our next adventure with the leaves changing color. Happy riding. :)

We arrived late in the day just as storm clouds were rolling in, but we managed a ride to Riverdale and returned to Alma just after sunset (17.5 miles). The trail appeared to have been recently re-sealed and, except for a 100 yard section west of Warner Road, it was buttery smooth. The only hazards encountered were the numerous bunnies running across the trail in front of us.

Planned and completed the entire trail starting from Grand Rapids Comstock Park to downtown Cadillac and back, last weekend. Was riding a gravel bike and can say that the gravel sections including the paved were so much fun to ride on. That being said, there are some deeper gravel and sand sections, mainly in the smaller cities at the crosswalks, so beware. Not bad, but you’d want to keep your eyes out for it. A fair amount of restroom stops, if you plan them. Highly recommend stopping in Rockford for a brew. Abundant campgrounds in Cadillac. Very much a friend and family group area though, so a little clustered. Stayed the second night at the Young’s Lake Campground and I could not recommend more! Very friendly owners greet you at the front and it’s not too big. It has its own little beach right in front of a lake. Some winding roads to get there, but super worth it. The stars were amazing. Great trail throughout, but when they do get to paving the entire trail, I’m sure it’d make the distance a lot easier and more accessible (although I personally liked the silence with no one else around but nature) FYI saw some Blue Racer snakes on the trail near Cadillac. Nonpoisonous, but you’ll be surprised. Recommend friendsofthewhitepinetrail.com for more details along the trail.

We rode from Alma to Erdmore and back.

The first 5 miles (or so) headed westward are smooth, but after that the trail deteriorates with frequent hard bumps (much repair is needed). The entire trail is over-grown and we were constantly dodging branches and thick weeds (again, attention needed). Few restrooms. No mile markers.

A high spot - 3D ice cream and pizza in Vestaburg. Great food, especially the ice cream, at reasonable prices.
