The park has some great informational signage that tells you about fossils in general AND the fossils you’re likely to find onsite.
In addition to the signs at the foot of the hill, they’ve marked the hillside with signs that specify the area of bedrock.
The park is absolutely free (no permit needed and no admission fee) and is open dawn to dusk. People from all over the United States have come here to hunt for fossil treasures.
The City of Sharonville states on their site that there’s also a trail that leads to a hilltop view of Cincinnati. I am sorry to have missed that and will return to check it out, especially while the trees are bare and the air is clear.
There is a water fountain and a few picnic tables but there are no restrooms. Wear sturdy shoes as the hill is (of course) rocky with uneven pavement. You might want to bring bags for your treasures too.
Trammel Park is located at the end of Tramway Drive (off Hauck Rd.)
