Skiing was popular during the 1950s at a ski hill located adjacent to what is now Blue Forest Drive. In the summer of 1956, the valley below the ski hill was the site of Bathurst Manor Day Camp, later Forest Valley Day Camp, and now a part of the Forest Valley Outdoor Education Centre. At its peak, it was the largest privately owned summer day camp in Canada, with over 900 campers, and operated through 1993. In 1973 the grade ten students from Downsview Secondary School built a suspension bridge across the ravine as part of their workshop experience. The bridge was dismantled some years later when it was considered an insurance liability. Beginning in 1998, Camp NAORCA summer camp operated by Toronto Parks, Forestry and Recreation Division moved here from its previous location at Seneca College, King Campus, and the Toronto District School Board uses this space during the school year to educate 21,000 students per year.
