Hike in Any Season

Oak Ridges Moraine Trail

The Oak Ridges Moraine stretches for over 160 kilometres across the most populated area of Ontario. It is the source of 65 major streams or rivers and provides clean, safe drinking water to over a quarter of a million people living on the Moraine. The Moraine forest, wetlands and open meadow are vital in maintaining a healthy ecosystem for Toronto and the GTA. It also provides beautiful space for recreation use.


The Oak Ridges Moraine Trail is a key water resource, a rich bank of bio-diversity, and a beautiful landform ideally suited for hiking.  Much of the surface is said to have a kame and kettle relief.  Hummocky hills (kames) are interspersed with hollows (kettles).  The hills are composed of sandy and gravelly materials with the underlying till or boulder clay sometimes protruding to form high ridges.  A kettle forms where a huge block of ice broken off the glacier is surrounded or buried by materials released by the melting glacier.  When the ice melts, a hole is left, often forming a lake, such as Mary Lake and Lake Seneca in King.   


There are 7 different trails for hiking in King.

The Oak Ridges Trail Association offers guided hikes on a year round basis.  These are a fabulous way to get close to nature, meet new people, and have some fun exercise.
