Arisaig Provincial Park overlooks the warm waters of the Northumberland Strait and offers a fascinating window to life on earth some 443 to 417 million years ago. One of North America’s most continuously exposed sections of Silurian rock, representing 4 million years of earth history, is found here. These sedimentary rocks are rich in fossils and features that have helped geologists interpret the ancient environment of this area.   

A 1.6-km (1-mi) loop trail provides access to many interesting features. From the interpretive kiosk, the trail winds towards the shore through a forest of white spruce. The shoreline portion includes a viewing platform and several access points to the beach. Another viewing station overlooks Arisaig Brook. From Arisaig Brook, the trail climbs a short but steep hill to the top of a small open field, where it returns to the kiosk along the ridge.
