Blue Heron Trail
This trail connects the visitor center to the
campground and is one-half mile long. It runs alongside an
oxbow lake that formed when the Meramec River cut a new
channel and began flowing along a different course. This
trail passes by Onondaga Spring, the natural entrance to
Onondaga Cave and the site of the old Davis Mill. During the
spring and summer months this trail is decorated with bright
orange butterfly weed, wild hyacinth and delicate wild
columbine, all of which grow along the bluffs and rocky
hillside glades of this trail. Blue Heron Trail is marked
with blue arrows.
Deer Run Trail
This trail makes a two- and three-quarter mile
loop. It starts at the amphitheater trailhead in the
campground. This trail will take you through upland forest
and glades, and treats you to some scenic views of the
Meramec River from the bluffs along it. Deer Run Trail is
marked with green arrows.
