Ontario Rock climbing 3,476 routes in region

Canada's 2nd largest province by area, and largest by population, with most of the population along the north and west shore of Lake Ontario -- metro Toronto and outwards.

Ontario is of generally low relief -- the highest point is about 690m (2260ft) above sea level. This tends to make for a lack of large cliffs and long routes, so Ontario has a reasonable amount of decent cragging, but nothing that is destination climbing.

The northern parts of Ontario tend to be nearly uninhabited wilderness and crown (publicly owned) land. Southern and south-western Ontario, especially the areas around Toronto, are more densely populated and access issues are often complicated.
