Filled with underground caves and streams, meadows and forests, the Eramosa Karst is one of the watershed’s unique natural gems. Eramosa Karst is located in the south western section of Stoney Creek area of Hamilton. A perfect location for hiking, nature appreciation, and education, Eramosa Karst is a one-of-a-kind property in Hamilton’s natural inventory.

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.

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.
