Thornton Bales Conservation Area

Nicknamed "The 99 Steps", this conservation area features an accessible lookout to enjoy the breathtaking panoramic views at the ridge of the forest. After that it gets a bit more challenging on the Red Oak Trail.
The only downside is there are only 8 spots to park (and parking on the road will get you a ticket or towed) so if there's no room try nearby Scanlon Creek in Bradford or Rogers Reservoir in East Gwillimbury.
