Thornton Bales Conservation Area
Thornton Bales Conservation Area is famous for its steep slopes and rugged beauty. This Area of Natural and Scientific Interest (ANSI) is part of the Oak Ridges Moraine, and has an elevation that drops 54 metres from its southwest corner to its northern boundary.
Nicknamed "The 99 Steps", this conservation area is best suited to people who are in good physical condition and enjoy a challenge. Water bottles and supportive footwear with rugged soles are strongly recommended for hikers targeting these woodland trails. Among the wildlife that can be found in this ravine-like setting are pileated woodpeckers and white tailed deer.
The Koffler-Bales side trail provides access from Thornton Bales Conservation Area to the University of Toronto’s Koffler Scientific Reserve at Joker’s Hill.
Fun fact: The change in vertical elevation from the top of the 99 steps to the bottom is a larger change in elevation than the drop over Niagara Falls!
The Thornton Bales Management Plan is now complete!
What's a Management Plan? A guide that establishes how we'll care for a property in a way that balances recreation and conservation. Through public consultations, goals and strategies are set to implement enhancements.
Management Plans are reviewed periodically to ensure the special green spaces we know you love stay healthy and accessible. View the final plan here!
