Located on the outskirts of Arkona, Rock Glen Conservation Area is a unique island of nature within the Ausable Bayfield watershed jurisdiction. Whether taking a hike along the Ausable Gorge or within Rock Glen's important Carolinian forest, you'll see many trees, plants and wildlife that are provincially distinct to this area.


The park is home to the Arkona Lions Museum and Information Centre which houses an impressive collection of Devonian Era fossils, minerals, and artifacts found in the local area. There are stairs, boardwalks and bridge allowing visitors to safely explore the steep sides of the glen and the 10.7-metre high waterfall just upstream of the Ausable River.

Visitors and amateur archaelogists from all parts of North America have found many fossils in the exposed beds dating back 350 million years. Scientific names for these ancient treasures include crinoids, brachiopods, and trilobites.

The story of civilization around Rock Glen dates back to the time when the Paleo or Early indigenous peoples utilized the nearby hills to hunt the barren ground caribou some 10,000 years ago. Succeeding the Paleo age were the Archaic people who had adapted to a much milder climate some 6,000 years ago. The museum displays "fluted points" associated with the Paleo age and many "cache" blades from the Archaic indigenous peoples.

Accessible trails allow all visitors to see the park highlights including the scenic lookouts, museum and picnic areas.

This is a growing destination for weddings. #RockGlenWedding
