The riverbed at Rock Glen Conservation Area is famous for its Devonian-era fossils, dating back more than 350 million years, long before dinosaurs existed. At that time, this region was covered by a shallow tropical sea. As Rock Glen Falls and the Ausable River erode the surrounding rock layers, fossils are continually exposed along the creek bed. Visitors often spot remains of ancient marine life such as brachiopods, horn corals, and crinoid stems embedded in the limestone. Fossil collecting is allowed here, but only one fossil per person may be taken and digging or tools are not permitted.

The Ausable River Trail is a shaded path through southern Ontario’s Carolinian forest, with steep banks, tall trees, and quiet stretches along the river. The route includes some muddy sections and minor bushwhacking, especially near Mystery Falls, a secluded 5-metre waterfall tucked beneath an overhanging rock ledge just a few steps off the trail. It’s a relatively moderate trail with a few scrambly spots, so it’s best tackled with good footwear to enjoy exploring this beautiful area.
