The Milne Outdoor Education Centre is located at Roy H. Crosby Public School in Markham, Ontario, CANADA. Established in 1990, Milne now serves 38 schools in the southeastern portion of the York Region District School Board. The centre is operated by one York Region teacher serving a term of four years and one outdoor education technician.

Adjacent to the Milne Outdoor Education Centre is Milne Dam Conservation Park. Located in the heart of Markham, Milne Park is a 120 hectare urban wilderness that has become a central feature in this community. The Rouge River, flowing from its headwaters in the Oak Ridges Moraine to its mouth at Lake Ontario, bisects the park from east to west and represents Milne's most significant natural feature. Today, the park contains a remarkable diversity of natural communities supporting a wide range of plants and animals.

In many respects, the Milne Centre is ideally situated. Most visiting schools are found within a 15-20 minute radius by bus. When in the park, students are introduced to an important element of Markham's natural heritage. They see direct evidence of both the positive and negative impacts their town has had on the natural environment. Most importantly, they experience the many interrelationships that exist between humans and nature and discover that there are numerous ways that we can contribute, both individually and collectively, to protecting and enhancing the environmental health of our community. Many positive elements have combined to produce a unique site, rich in potential for well designed environmental education programs.
