Stunning and windy trail that is known for being steep and rocky. While the wooded areas surrounding the Declue Trail are familiar, the off-trail environment offers a unique savannah and prairie ecosystem. Grassland vegetation, and wildflowers define this landscape. The local flora has adapted to thrive in these dry conditions, with trees often growing horizontally due to limited competition from other trees or shrubs.

Greensfelder Park, once a site of logging, mining, and various industrial activities in the 19th and early 20th centuries, has transformed into a cherished natural oasis. Its journey from a rugged landscape to a serene park began when Charles Evans offered a 300-acre tract to the City of St. Louis for use as a park in the late 19th century. Although the dam constructed in 1895 was washed away a year later, the mining activities continued. In 1963, this historical land was generously donated to St. Louis County by the Trustees of the St. Louis Regional Planning and Construction Foundation. The park was originally known as Rockwood Park but was officially renamed Greensfelder Park in September 1965. Today, it stands as a testament to the area's rich history and its transformation into a beautiful parkland for all to enjoy.
