Rode the trail starting in Osawatamie. Trail was in great shape, though some parts had a lot of leaf coverage. Despite this, no issues with surfaces or slippage. Such a peaceful trail to ride. And it flows super fast.

40 miles of outstanding trail. Rapid improvement of Flint Hills nature trail due to its designation as a state park. From Osage city to Allen the trail is 20 feet wide of crushed lime stone. From Allen to Council Grove 15 feet wide crushed lime stone with rock formations and fossils on both sides. Bathrooms,food, and water in Osage city, Allen, and Council Grove. Camping available in multiple sites along the way.

The wife and I have just started walking, as a means of much needed exercise. I am a former powerlifter and she was once an athlete, in golden years past. We have been walking by Shoal Creek, a great walk, and it is nearer to our house, but once we walked this trail we both fell in love. Great walk. Even when it is busy, there are quiet moments to see nature and wildlife. Most people you pass say hello, nod, or let you pet their dog. That may just be the people of Joplin, but still it is an incredibly beautiful, friendly, and surprisingly strenuous walk. We are gonna do the whole thing soon, and once we do she says we are going to mountain bike the whole thing. What a great natural spot to escape to. Joplin is blessed with such beautiful natural settings.

This trail is great for a stroll or a quick bike ride. Beautiful scenery and you can start either off of Allan St or from Briarbrook.

Having already biked from Ottawa to Welda, I went from Welda to Humboldt round-trip so as to complete the last remaining segment of the trail. Technically, the section from Iola to Humboldt is the Southwind Trail Trail, however it functionally is an extension of the Prairie Spirit. Regardless, I remain impressed with the condition quality of today's 26 mile section. The trail was packed down with minimal loose gravel, so as to allow for a surprisingly smooth ride. Simply excellent condition. Considerably more tree cover than I expected as well, which was quite welcome on a hot day. Several sections had foliage covering the trail to create a tunnel effect, which was a treat. If you have the opportunity, do yourself a favor and treat yourself to a trip on this very well-maintained rail trail.

Not realizing that the Prairie Spirit Trail stopped in Iola and transitioned into the Southwind Rail Trail from that point to Humboldt, I was surprised to see the Southwind sign after biking down from Welda. What a pleasant surprise it was. The trail is in excellent condition, packed down with minimal debris/rocks, and made for a reasonably smooth ride. More shade was provided by foliage than I expected, which helped keep me cool on a boiler of a day. Not sure who to thank for maintaining this trail so well, yet I hope they read this - I'm grateful.

First time on any section of this trail, and rode from Ottawa to Richmond and back. The trail is in good shape - no vegetation overgrowth, no trees blocking the path. Care should be taken when crossing roads, as there are some significant bumps at the intersection - if you don't stop or slow down significantly it could be problematic. The trailheads at Ottawa, Princeton, and Richmond all had working restrooms and maps. The only challenge with this trail is that it's not particularly scenic, however that's the nature of my home state and not on the folks who created and maintain the trail. It's flat, straight, and a great option for a safe and pleasant ride.

First time riding this trail. Well maintained, very quiet trail. Rode Humboldt to Iola today, and only saw one other rider the whole time.

Today we rode the Flint Hills Trail from Osawatomie to Ottawa and back. We had a great time and this trail is highly recommended! The trail is a "Rails to Trails" route that follows the Marais des Cygnes river, so it is predominately flat. The gravel surface is packed very light chip, so almost any type of bike will work (we rode gravel bikes). In a few places, the recent heavy rains washed away the light chip top coat and exposed the more coarse RR bed gravel below, but it is not a problem. We did not see any of the thorns etc. mentioned above in posts from previous years. The trail head is a little hard to find, and Google maps did not help. If you find the Osawatomie elementary school and then proceed down that same road about 3/4 mile further, the trail head (with some parking) is on your right. Leaving on the trail from Osawatomie, the first 6 miles are completely shaded by trees arching over the trail. After that the trail is about 1/2 shaded and 1/2 open meadows - so this is a great trail for warm summer days (and should be beautiful in the fall). There are many bridges, views of the river and wide open farmland to see along the way. Today, at 9 miles in, there was about 200 yd where water covered the trail from the big overnight thunderstorms, but this is not normal. There are no drinking water stops along the way - so bring at least 2 good sized bottles per person. There are however farm houses all along, so if you really needed help in an emergency, it is not far away. Ottawa is about 18 miles from Osawatomie and you will know that you are close when you pass under the I-35 bridge (about 2 miles to go). If you want lunch, turn left off the trail at 7th street (it is well marked), go ~1 mile south on 7th and you will hit Main street. Subway is 2 blocks to your left (9th street) on Main, or you can go to downtown and have a variety of food choices. We had a really nice ride today and hope that you can ride this trail soon too!
