I rode the McPherson side today and with all the rain the region has had, the trail is still in fairly good condition. There are some soft spots in areas but most of al it’s a good ride.

This is a lovely trail. I camped at Vassar Lake for a few nights and rode sections out and back each day between Council Grove and Osawatomie. Trail conditions were great for a gravel, mountain or touring bike. There are a few rough bridges, and a few patches of ballast or deep sand, but nothing that will ruin your day. My first morning I followed a coyote following a turkey for the better part of a mile. In Ottawa you can also connect to the Prairie Spirit trail, which is also nice.

This trail is not ready for prime-time.
Unlike the R-Ts that I've done (GAP, Katy, Mickelson), there are no dedicated services such as water (cisterns or pumps), bathrooms or portapotties, no mileage signage, not even signs identifying towns at crossroads. Essentially NO SERVICES. I did count four (I think) benches on the 103 miles we rode. Though I have been told this will change quickly since the State has recently taken over the trail, about a quarter of it is virtually impassable due to inappropriate maintenance, if any. That's from about five miles east of Council Grove on and off to Osage City. 2-4 inch ballast rocks are dumped on the trail without grading or filling, no gravel for miles (just dirt jeep trail), no side rails on unimproved bridges (dangerous), grading done in wet weather where the grader tread tracks have become miles of almost-highway rumble strips and, finally, trash heaps along side the trail.. A terrible riding experience. Add to that an approximate three mile detour just west of Ottawa on yucky gravel county roads (not marked on any - including TrailNet - maps, but clearly a long-term function of the trail).
Now, from Osage City east to Osawatomie is from passable to good enough, mostly on the positive side of that spectrum.
BUT, the people we met were all wonderful, great experiences at every interaction. The Cottage House in Council Grove and the Koch Guesthouse (AirBnB) in Osage City were delightful, and Jeff and Yon at the Ottawa Bike Shop were outstandingly - I mean really - helpful.
If you want to do the Flint Hills R-T, do the eastern half or wait till the state at least fixes the surface on the western side. Otherwise, it can be a miserable experience. Either way, once the trail is fixed, it's still a long way from the standards set by the nearby Katy.

I began running along this trail on Friday afternoon on 4/12/2019. The weather was about 52°, sunny, and a bit windy. I found the trail to be difficult to run along. The trail is gravel, but not maintained very well. There was a steady undergrowth about 8” high that blanketed the trail. I found myself dodging bushes and dead, fallen trees lying across the path. In the two miles i ran, there were about three gates. After the fourth, i met a herd of cattle, and that’s when I turned back. Otherwise, the trail is very peaceful. I recommend it for walking or mountain biking. If tou do bike it, be sure to bring an extra tire!

Felt like riding a cobblestone road. I have great shocks on my mountain bike too.

Rode on an unseasonably cool and overcast July day. Trail is in excellent condition. We rode our street bikes. This section is doable for the casual rider and for families. Take water, there are no services. Beautiful ride through the flint hills. Bushong is the high point in this section.

Great ride on a super nice spring day. The trails were in very good condition. The only problem that we encountered was the 2 mile (2.5 mile?) detour that is west of Ottawa. It is on gravel roads, which is no problem for gravel riders. There are also a lot of dogs, most are of no consequence... but be on the lookout for an Ill-tempered pit bull on the west end of the detour. The owner was there and able to contain him so we could pass. This is the only reason I couldn’t give our experience 5 stars. Next

Did a 25 mile out and back east of Council Grove. Overall good condition with a little loose stone. Quiet ride with beautiful views of the working and natural landscape.

This trail has lots of shade trees which is perfect on hot sunny days! Great distance for a group to bike. Scenic and well marked! Will bike there again !
