About the Ganaraska Forest

The 11,000 acre Ganaraska Forest is one of the largest blocks of forested land in southern Ontario. Today the forest is a living example of how the principles of integrated resource management can be used to balance many different uses of forested lands on a sustainable and ecologically sound basis. The forest is home to the Ganaraska Forest Outdoor Education Centre, and public washroom and shower facilities. The area provides abundant recreational opportunities and is managed for a sustainable yield of wood products. Day passes or annual permits are required to use the forest. Office hours are 8:30 am - 4:30 pm weekdays, the Gatehouse is open for sales on weekends from 9:00 am - 4:00 pm, or day passes and memberships can be purchased online.


Poison Ivy is very prevalent on the Ganaraska Forest recreation trails. The oil from this three-leafed plant can get on exposed skin and cause an ugly, extremely itchy rash; a reaction that has a three-day incubation period. In order to minimize the effects of exposure, it is advisable to wash any exposed skin with detergent, and rinse well. There are showers in the washroom facilities located across from the gymnasium at the Ganaraska Forest Centre.

It is also wise to wipe bikes, shoes, tires and gear that may have come into contact with the oil. Pets can also carry the oil on their fur for a period of time after exposure. A good rule of thumb is: Leaves of Three? Let them be.
