ORCT: 👀 Tri Century Challenge 👀 Mystery Cache

This section of the Oak Ridge Trail (ORT) has a series of challenge caches covering a 3km section from Lakeridge (Durham 23) to Ashburn Rd and will take hikers through a lovely section of wooded forest, past wetlands and open meadow that make up the Oak Ridges Moraine. The Oak Ridges Moraine stretches over 160 kilometers north of the GTA and is the source of 65 major streams or rivers, providing clean drinking water to over a quarter of a million people who live on the moraine.
