A huge shoutout to the organizations that put this trail together, maintain, and promote it - its remarkably well done. There are a few spots that could use some more signage (Westerville is pretty bad) but overall from top to bottom it's hard to get lost. I did this trail in 4.5 days from Cincinnati to Cleveland the last week of October with almost no bike experience. I also used a busted up old mountain bike from the 90s and had pretty much no problem with it.

I discovered this trail at the southern end of the Cardinal Greenway, and figured why not check out the trail by the gorge? It may well be the most scenic part of the entire connected trail system, going up to Gaston and including the White River Greenway Trail in Muncie. There's lots of green, a river (albeit usually hidden from view), and a good amount of elevation change in a short time. Definitely worth adding on to a Cardinal Greenway ride if you have the stamina to spare.

There also are some nice parks along the way, including by the piano/record factory, and at the veterans park near the northern edge, where you can see the difference in size between a light tank and a main battle tank in real life.

Still, there are a couple shortcomings that make this a trail that could easily be a 5, but isn't quite there yet. The largest is that there is a section near the southern end where the pavement is quite rough, which also corresponds with the steepest area, making it potentially hazardous. The connector up to the high school is even steeper and in rougher condition. There should be the next priority for fixing up.

There also was a tree across the trail almost at the southern terminus, which appeared to have been there for some time, and several of the wooden benches in the southern section were not in great condition any more.

It did look like the section by the veterans park was pretty new trail, and that the overseers were still working on an overlook above that park, so this trail may well still be receiving investment. With a little TLC on the southern section as well, it would definitely be a 5 star trail.

I rode the section of the trail from Richmond to Gaston over two days - essentially, all except the part above the gap to the north. It's a really good trail, but there are just enough shortcomings that I hesitate to put it at 5 stars, particularly compared to trails I've been on in West Virginia and Pennsylvania earlier in the year.

First, I'll note that I didn't notice any pig farms, despite expecting to on the southern section, nor any Rottweilers. There were some cow farms and a horse farm, but the only hazard were the many walnuts on the trail. I did see two cats, a lot of chipmunks, and quite a few blue jays, though ironically not a single cardinal.

The scenery is mostly fairly narrow wooded areas, with farms on the other side, though there are a few areas of denser wooded areas, notably by the nature preserve south of Muncie. This can be pretty, but it's also only partially shaded, and the afternoon sun slices through the trees pretty effectively. If you're doing a longer section, I recommend going northwest in the morning, and southeast in the afternoon if possible. I was going northwest and west in the afternoon of the first day, and the sun was doing an admirable job of trying to blind my left eye.

Amenities are good, but just short of great. There are restrooms every 4-5 miles, most of them with hand sanitizer, which is quite good. There are a decent number of water fountains as well, but of the three I tried on the northern section, two smelled bad, and one (by the Hitching Post, technically off of the White River Greenway but close to the Cardinal Greenway) didn't work. The southern section was reliable in this area. Outside of Muncie, there aren't a lot of places to pick up water in the northern section either, so err on the side of packing more water than you'll need.

The trail condition is generally very good, though it can be a bit bumpy in spots in Muncie. McGalliard Road is a more highly trafficked road crossing than most trails have, but it has an island in the center so you only need half of it to be clear at a time. I recommend jogging the bike across halfway at a time if it's a busier time of day.

The elevation gain is not negligible. Including segments on the White River Greenway in Muncie, and the Whitewater Gorge Trail in Richmond, I logged over 2000 feet of elevation gain, and it was noticeable, especially on the southern section where there were moderate, but extended, hill climbs. By comparison, I logged less than 1200 feet of elevation gain on the Greenbrier Trail in West Virginia, which is also longer. So don't assume that because it's in Indiana, you won't have some decent climbs!

I also should note that it's worth going into town in Muncie, whether that's the White River Greenway, which intersects with the Cardinal Greenway in two places, or grabbing some food at some of the excellent restaurants or breweries downtown, which is easily accessible from the trail. I always try to find a cool town or city to serve as a base when exploring a new trail, and Muncie did a great job in that regard.

I tried to ride from New Bremen to St. Mary’s. I read some reviews, but it wasn’t clear. I also talked via phone to someone who lives in New Bremen and he encouraged me to take the path. Well, 1 mile north of town it was just tall thick grass. Had to do a detour on busy roads

Got 6 miles in starting by Muncie.
This portion of the trail is just as the other couple parts I've experienced.
The paved trail is mostly flat, level and equally shaded/open.
The one thing to be aware of is a couple bad spots/cracks in the pavement that could result in an ankle injury or biking issue, but this should not deter one from using the trail.
So as always, if in the area and want to get a couple miles in, this should do.

Good for walking and running, a little narrow and cracked up in spots for cycling. No roller skates allowed around the lake.I took the Gorge trail and Walnut Falls trail to add some distance. Recommend.

Enjoyed the well maintained trail but at a few points it was confusing.

I parked at the train station in Trotwood and rode north west to the end of the trail in Verona and back. Trail is in good condition with places to take a break. The trail goes through the country and is very scenic. If you’re looking for a nice easy enjoyable ride this is it.

This is a trail of considerable contrast. The central part of the current trail encircles Austin Landing, a mixed-use retail district that includes retail stores, restaurants, motels, office buildings and contemporary apartments. There is lots of traffic in and around this mall as commuters enter and exit Interstate 75 at adjoining Exit 41. The trail along Austin Pike (or Boulevard, in front of the Mall) is very busy. At each intersection between trail and roadways there are crossing buttons at the crosswalks. However, with the exception of the crossing at the intersection with Springboro Pike none of these buttons work. You’ll just have to wait for the automated timing for the crosswalk signals to activate in order to cross these streets and highway ramps. My suggestion is to avoid riding along Austin Boulevard as much as possible by riding the portion of the trail that loops around Austin Landing.

There is much less traffic as you move toward either the current eastern or western end of the trail. To the east you will ride around the Miamisburg Soccer Association soccer fields and then through the Medlar Conservation Area. The conservation area is a preserve of over 400 acres that contains mature woods, fields, shrub-scrub habitat and wetlands that protects some of the last quality open space in southern Montgomery County. When you enter the Medlar Conservation Area after coming from Austin Landing it’s like you are in an entirely different world. The trail meanders through this preserve as it makes its way toward the Great Miami River Trail on the eastern bank of the Great Miami River. Once you enter the Medlar you will quickly become aware that you are dropping in elevation. That's not so bad if you are only traveling westward, but challenging if you know you will have to climb back out to return to your start. Fortunately, the planners of this trail put in enough switchbacks into this portion of the trail to make the climb reasonable for most adult riders. Young children would find this climb difficult.

The trail east of Austin Landing runs for about 2 miles along Austin Boulevard/Pike. This portion of the trail is less developed and mostly residential. It passes by Dayton Wright Brothers Airport, a small public civil aviation airport, and ends near Robert F. Mays Park in Washington Township, Ohio. This trail is intended to connect the Great Miami River Trail with the Little Miami Scenic Trail. The trail will be extended further east into either Greene or Warren County depending on the route selected to connect it to the Little Miami Scenic Trail. When this connection between the two river trails will be completed is unknown at this time.
