Journeys in ancient and old growth forests
West Duffins Creek (Seaton Trail) 
The Seaton Trail follows the creek valley through a variety of forest types with fantastic views, creek-side walks, and patches of old-growth hemlock forest.
Park Name:  
Size: 250 ha
Age of oldest known trees: 200 years
Forest Type: Mixed 
Conservation Status: Provisionally Protected 
Land Use Designation: mixed, mostly publicly owned 
The majority of the creek valley is owned and operated by the Ontario Realty Corporation (ORC), with smaller parts by the Town of Pickering and the Toronto & Region Conservation Authority (TRCA). 
Most of the valley is younger forest, but along the steeper slopes some old forest and very old individual trees can be found. At the Forestsream stairway (just south of Clarkes Hollow parking) you ascend through a 130+ year-old hemlock forest. Pockets of hemlock occur at many places along the Seaton Trail, a spectacular and ambitious 13 km hike in the east of the GTA.
