Print Friendly MapThe Meramec Greenway Trail is a scenic route connects residents to the Meramec River and many parks in the region as it winds along the river and limestone bluffs, and through woodlands and the heart of several communities.
Just over 20 miles of the greenway are open in the five disconnected segments outlined below from west to east.
Eureka (1.5 miles, paved)
In Eureka, the trail begins at Lions Park, which offers parking, restrooms, and picnic pavilions. From there, the paved trail heads east for 1.5 miles, ending at the much larger Route 66 State Park. Over an expanse of more than 400 acres, the park offers hiking, biking, and horseback-riding trails, as well as river access for boating and fishing.
Glencoe (5.8, crushed stone)
North of Eureka, another segment of the trail begins in the small community of Glencoe and spans nearly 6 miles; there is a trailhead with parking at the end of Grand Avenue. This section of the greenway, known as the Al Foster Memorial Trail, has a crushed-stone surface and is heavily wooded.
Traveling east along the river from the trailhead, the trail follows the route of the former Missouri Pacific Railroad and enjoy the sight of soaring limestone cliffs and perhaps wildlife, especially white-tailed deer. Heading north from the trailhead (away from the river), you will be on the Hamilton-Carr Greenway, which takes travelers past the La Salle Institute campus and toward the Rockwoods Reservation. Farther along, you’ll also have the opportunity to connect to the Rock Hollow Trail. From there, the Al Foster Memorial Trail heads southeast, crossing under an active railroad trestle and entering Sherman Beach Park, where there’s another trailhead with parking. The trail continues east to its end in Castlewood State Park.
Valley Park (3.5, paved)
After a gap, the trail picks up again in the city of Valley Park. This segment is paved and stretches 3.5 miles from the Arnold’s Grove trailhead to Greentree Park in Kirkwood along the north bank of the river. Wonderful river views, a public boat launch, and distinct orange-hued sand make it a memorable experience. For the young at heart, Greentree Park also offers a remote-controlled car track. Midway, trail users can cross Marshall Road to enter Simpson Park, which encompasses forested areas and a large lake. There are also restrooms and water here.
Fenton (6 miles, paved)
On the other side of the river, 6 more miles of paved trail roll out from Unger Memorial County Park, where herons, egrets, and other waterfowl can frequently be found in the park’s shallow lake. South of the park, the trail passes a major soccer park and then a baseball complex before traveling under the interstate and into the town of Fenton. A short section of the route is on-road along Riverside Drive before becoming trail again in Fenton City Park, where trail users can stop for restrooms and water. The trail ends at George Winter Park on the banks of the Meramec River.
St. Louis (2 miles, paved)
The last open segment is a paved, 2-mile section completely within the county’s Lower Meramec Park. Thick river lowland forest dominates this trail. Waterfowl and other wildlife are plentiful here. Trailheads with parking are available at either end of the segment.
The Meramec Greenway Trail runs in five distinct segments between Lions Park (Eureka) and Lower Meramec Park (St. Louis), with parking available at both ends.
Parking is also available at:

Started in Glencoe at the miniature railroad depot. Trail started out promising but seemed to get more and more narrow and is poorly marked. We attempted to follow the Al Foster trail. This really isn’t a 10 plus mile trail as it’s broken up. We originally started in Eureka and quickly realized the trail stops after roughly 1.7 miles. Luckily for us that after a few miles of an ever shrinking trail, we decided it wasn’t for us. Got back to our vehicle and put everything away just before a storm came through.
Flooded just below Simpson Park on segment two. March 7th we are expecting rain the next 2 days so plan your route accordingly
We started south of Fenton. It took us 2 tried. We got to the northern terminus and dangerous stop sign. We rode back 11 miles. Trail all broken up and poorly marked both directions. Trail was paved and it pretty good shape
This has got to be the most ridiculous trail around. It's broken up and spaced out so far you almost have to drive a vehicle to reach section. Not to mention hope short each section is. The 20+ mile trail distance is VERY misleading.
This is my new favorite trail. We'd done the Rock Hollow portion before, but had never ventured past it. The Al Foster Trail was beautiful and pretty much completely flat. It was fun to see the miniature trains full of people along the route as well. This trail is top on my list!
We enjoyed this trail very much! Unfortunately it was a 1/2 mile too short for what we needed, but lovely paths that go through shade, sunny spots, and nice views of the river. It was a gorgeous day and while the trail had lots of activity, it didn't feel crowded at all! PLENTY of benches about every 1/3 mile to rest and relax. An absolute treasure!
First ride on the trail, I believe was segment 2, exceeded our expectations. Second ride was just as enjoyable. The first ride was during the week with thoughts the trial would not be very busy. It wasn't so we were able to take it all in.
The second ride was on a late Saturday morning. We expected the trail to be busy it wasn't. I believe it may have to do with the length of the trails and all the many areas to pull off and take break to enjoy the views.
I'm sure we will put this trail on top of our list.
first segment (Al Foster) trail is so gorgeous. perfect for lone bikers/walkers/runners and connects easily to Hamilton Carr trail at NW end and mid way roughly on western portion has the Rock Hollow trail. families...weekends in May-Oct the railroad runs [$4 donation] and is fun for kids. Trail is primarily gravel but is well maintained and is great for beginning bikers [even this 60+ new biker] and longtime bikers ...take the Stinging Nettle trail over to Castlewood to get some off road biking in. Excellent fun!!
We've traveled segment 2 from 141 to Simpson Lake and loved it. Will continue to go back. Kid friendly and very scenic.
