This is a very hilly park, and all of the trails are either going up or down for the entire length, some of it in the shadow of the Six Flags rollercoasters!
If you haven\'t been to Greensfelder recently, you\'re in for a pleasant surprise. The Dogwood Loop has been almost completely rerouted to lengthen it and bring it up to IMBA standards, as well as adding a number of new features, such as a banked s-turn, and some rocky sections. GORC has also added about 0.5 miles of new trail to DeClue which leaves almost all of the existing trail in place, but bypasses one unmaintainable section. If you like choosing your lines, fast narrow descents, and rocks to test your skills, then you\'ll love this new section.
Due to the number of trail features, and its rocky surface, DeClue is considered a fairly technical place to ride. Expect a tough workout, and some sections that may require hike-a-bike (for short runs). Dogwood is fast and flowy, with some rocky spots thrown in to keep you on your toes.
Trail traffic often includes horses, so be careful and courteous when encountering equestrian traffic. Always dismount your bike and go off the downhill side of the trail. But for the most part, this park is underutilized. Make sure and take the bug spray in the summer.
If you want to \"taste\" Greensfelder before diving in, ride the Dogwood trail first. Depending on how you choose to ride the loops, you can get in rides from 7 to nearly 15 miles. (pasted from GORCTRAILS.COM)

There are a number of trails here that really make you work for the downhill portions. Be prepared to climb. Im impressed with the upkeep on the many trails here. This is a great place to ride if you have a few hours on the weekend. Its one of my favs.
| ThankGreat trail lots of people
| ThankIf you haven't experienced the new Beulah section heading back to the shelter from the lookout, you are truly missing out. Technical climb out(CCW), but, oh so fun ridden back down (CW). Lots of challenges and 2 alternate lines in rock garden.
| ThankThere has been so much work done to this trail. It really is a world-class trail, especially for the Midwest. It is much longer than 2 miles. You can do around 18 miles at this park one-way by connecting with a couple other trails.
| ThankThe best in Missouri
| ThankGreensfelder is my favorite place to ride. I was surprised to see Green Rock so far down the list. There is only one review I guess is the reason. This trail is fantastic
| Thankwow! loads of fun with a good bit of rocks and roots, just about all do able by an old guy like me. stays out with a bit of a traverse then drops into valley for most of the circuit. the last maybe half mile regains all the elevation lost previously, and which seemed a bit unreasonable, but what goes down must go up ;-) all things horsey in evidence except the beasts themself.
| ThankThere has been so much work done to this riding area in the past few years. It's one of the best in St Louis. There are around 15 miles of trail now.
| ThankThis killer trail is part of a network of trails at Greensfelder County Park. There's so much good riding there, it's worth it every time I go. Right now the trail is in excellent shape.
| ThankRode Dogwood and parts of DeClue, Eagle Valley, Deer Run, and Green Rock. Most trail was fun and rocky. Some parts were overgrown and/or pounded into oblivion by hooves. In all it was a good place to ride and I can't wait to come back and try some other loops.
| ThankLots of offshoot trails. Good riding!
| ThankThis is a long trail that goes all the way trough Greensfelder park. It starts to the north in Rockwoods Reservation, travel clear through Greensfelder and ends in Rockwoods range. It utilizes part of DeClue, Dogwood, and eagle valley trial and is a mix of single and doubletrack. I set my review at advanced due to the amount of technical trail features and the length of the trail. If you park at one end and ride it as an out and back it is a long ride!
| ThankShort trail that leads to a scenic overlook. The view is well worth the detour from the main singletrack in Greensfelder park. If you are on this side of the park take this short trail to the overlook and enjoy the view while taking a nice snack break.
| ThankThis is a trial mostly used by equestrians and you can tell it when you ride there. It is pretty beat up and needs some serious maintenance but unless it is going to get a lot more mountain bike traffic I'm not sure it will get the attention it needs. the only reason I graded this as intermediate is because of the damage it makes it tougher to ride for beginners. If you are on a full rigid I would suggest staying away from this one!
| ThankThis is a partial singletrack and part doubletrack trail with very steep climbs that are a bit long! There are some serious lung busters on this trail! You better bring your big boy or girl legs on this one! Some good fun trial though, come out and enjoy it!
| ThankDogwood is the most beginner friendly trail in the Greensfelder trail system. This trail is chock full of buff fast flowy singletrack. There is some descent elevation change but it is still ok for a beginner, it is good for building up your muscles and getting use to tougher trails and then you can move onto DeClue trial just over Allenton Rd.
| ThankDeClue trail is the most technical trail in the Greensfelder trail system. It is jam packed with rock gardens and steep baby head rock covered climbs and descents. Hit this trail up to hone your mountain bike skills set. I enjoy the challenge that DeClue puts in front of me and every time I ride it I feel I become a better mountain biker because of it. Every time I clear a section that I was unable to clear the ride before! Super fun trail, go getcha some!
| ThankBeulah is an extremely eroded mess at the moment and is stupid steep. It is in the planning stages at the moment but it is going to be a multi year redesign and re-rout that will add a few miles of buff singletrack to this wonderful park system. Keep an eye out for this to start and come out and help during one of the many trail builds that will be planned for this project!
| ThankGreensfelder park has fast become my favorite park to ride and is packed full of technical features and rock gardens. and in between everything there is fast buff singletrack. There is going to be a lot of activity in this park for the next few years to re-route some seriously eroded trail that was equestrian only trial into sweet multi use singletrack! We are looking to add many more miles on buff sinlgetrack for the mountain bikers very soon. Keep an eye on this jewel of a park in St. Louis county!
| ThankGreensfelder is one of the more technical parks to ride around the St. Louis area. There are a lot of rocky climbs and descents. Quite a few areas that beginners will need to hike a bike and lots of fun rolling hills that this part of Missouri is known for. It is a fun park to ride even as a novice there are good challenges with more than enough space between to keep you from getting frustrated. This was the second park I ever rode and had a blast. You can really pound out the miles here too. Pretty easy to get 20 in one day.
