Karst Features

Karsts are geological formations including underground drainage, caves and passages caused by dissolving rock, found in limestone formations like the Niagara Escarpment. The Eramosa Karst contains examples of 16 different karst features. The Ontario Ministry of Natural Resources designated the Eramosa Karst lands as an Area of Natural and Scientific Interest in 2003, because it is believed to have the largest number of unique karst features in any single area in the province. Several of its karst features are provincially significant. These include: soil pipes, a high concentration of suffosion dolines and sinking streams, overflow sinks, dry valleys and a 335 metre-long cave (the tenth longest in all of Ontario). There is also a natural dolomitic limestone bridge at the entrance of one of the sinkholes. The surface and groundwater drainage system that created the karst originated about 13,000 years ago, after the last glacier retreated. Today the drainage system sustains the karst and provides examples of karst processes and features in different stages of development.

Walking on the Trails

The diversity of geological and hydrological features, and its central location in the Greater Golden Horseshoe, makes the Eramosa Karst one of the best sites in Ontario for education and research opportunities. Click here for more information on HCA education programs.

With more than four kilometres of trails, boardwalks and bridges take you through escarpment forests and meadows, unique geological formations and a beautiful natural amphitheatre. Interpretive panels throughout display facts about the area's natural inventory and history.
