Meramec Greenway

Greentree Park to Arnold's Grove Park

This greenway and surrounding roadways were impacted by flooding.  Cleanup is underway, but be aware there may still be some sand, mud or other flood debris on the Riverside Trails at Simpson Park. A small section of the greenway along the river near RC park has been rerouted due to damage to the trail. There is still sand and mud adjacent to the greenway in some areas that may wash across the pavement– particularly after it rains. You can still explore and enjoy the greenway, but please use caution. A permanent fix is in the works. 10/10/2017

Things To Do


Trail Info

3.6 Miles

This 3.6-mile paved trail travels between Greentree Park in Kirkwood and the Arnold’s Grove trailhead atop the levee in the City of Valley Park. It is flat and shady with some up close views of the Meramec River. It is an ideal trail for new cyclists and we often recommend it for families with small children because of the shade, slower pace and many places to stop along the way.
