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.

Biked the trail from Middleville south on a cool clear weekday in late September. Trail was not crowded but a bit bumpy in a few spots. We also biked the new portion a mile long and it was beautiful. Nice restaurants in town near the trai.

Perfect for the family! Take bug spray if you’re walking.

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.

Not a bad ride for locals. Drove a couple hours to ride here. To be clear, this is mostly a paved path by the road with houses you ride by. You only have a few lake overlooks. Was hoping for much more lake and a lot less riding through what felt like a woody housing addition
