Oak Ridges Trail Association
We are the Oak Ridges Trail Association (ORTA) and we want you to join us! Come out on one of our organized hikes on weekdays and weekends. The fun of meeting people who share the same love of the outdoors is gratifying. Get some good, low impact, enjoyable exercise and bring the children along, too.

At present about 275 km of main trail, plus various side trails, have been completed. The trail starts in the west with a link to the Bruce Trail, north of Mono Mills (Hwy #9 & Airport Road), and continues through the Northumberland Forest in the east, before splitting to two gateways at Castleton and Warkworth.   More...
