Grotpeter Trail is a 2.7 mile heavily trafficked loop trail located near Saint Louis, MO that features a river and is rated as moderate. The trail offers a number of activity options and is accessible from March until October. Horses are also able to use this trail.
Varied routes and the challenging terrain with numerous elevation changes make this a popular trail with all users. In addition to the main trail, five white connector trails, totaling 2.6 miles, are available to enhance, shorten or lengthen the users experience. From the trailhead, east of the park office, the trail crosses Kiefer Creek Road before climbing up and over a hillside. The trail then winds up another hill to the top of a long ridge. White connector trails 1, 2, 3, 4 and 5 can be used to bypass steep sections of the trail. After reaching the pinnacle, the perimeter trail follows the crest of the ridge before starting a long downhill back into the Kiefer Creek valley and back to the trailhead.
Beautiful trail. Some intense inclines
Great trail, well marked, mostly uphill, rocky down hill! Less traffic than other Castlewood Park Trails.
Easily my favorite trail in STL. Varied trail surfaces, lots of inclines and declines, and the beauty of these Woods make for a great hike. it takes me about an hour and 15 minutes to get round the entire thing but there are offshoots that allow you to lengthen or shorten as you like. It is primarily a mountain bike trail so be prepared to step off the trail as they come by.
In the summer, it gets hot and muggy back there so bring water. And it gets pretty ticky too, so don't skimp on bug spray.
For an extra bonus, pick up the Lone Wolf trail connector to go up on the bluff overlooking the Meramec River. Great views.
This trail was great. It was well-maintained for the most part. I really liked how the walking surfaces were varied—it made it more interesting (gravel, hard packed earth, wood chips, etc)
There were only a couple parts that I found to be pretty tough, but I'm very new to hiking, and not in the best shape yet. There was a really long steep hill near the beginning that just kept going and going... but I felt fantastic when I reached the summit :-)
