It’s only a few minutes off of I-77, but it is hidden. GPS took us directly to it, just know that you’ll pass a large steel manufacturing plant and a neighborhood on the way.
The trail was a bit muddy, so I’d recommend having something to wipe / clean your shoes with afterwards. The preserve is not staffed, so you are free to roam and read the signs provided. The trail is clear (though muddy) and is marked well. Signage on site warns of alligators, snakes, etc. but we didn’t encounter any. There are also signs noting that certain parts of the trail may flood during heavy rains. Given the state of the walking path and the surrounding areas, this may not be the best stop for small children who tend to stray from your side.
Overall you can’t beat the price (FREE!) and it’s a nice place to stretch your legs if you aren’t afraid of getting a little bit dirty! :)
