Tourism is another important industry in Lambton County, especially along the lake and river. The community of Grand Bend and the Pinery Provincial Park are especially popular tourist destinations, attracting thousands of people each week throughout the summer to their long, uninterrupted beaches. The part of Lambton County along Lake Huron known as Lambton Shores depends almost entirely upon the seasonal industries of tourism and agriculture for its well-being. There are also popular conservation areas along the St. Clair River, and a conservation area named Rock Glen Falls near Arkona along the Ausauble River internationally known for its Devonian period fossils.
