The oldest provincial park in Canada, Algonquin is the go-to experience for nature lovers from the nearby metropolises of Ottawa and Toronto. Quite large, there are plenty of campsites along the exterior of the park, but the intrigue is in footing it or canoeing to the many campgrounds on the parks interior. There are innumerable picturesque waterways (okay, about 2400 lakes and 6 major rivers. Pretty much innumerable) and a diversity of plant and animal life that reflect the region's position between coniferous and deciduous forest.
The official park website provides information that outlines where you'll find campsites, whitewater adventure, serene canoe-rides, hiking trails, and the best of the park's natural attractions. Located a 3 to 4 hour drive from Toronto, make sure to pick up $16 day permits at the park office or a provincial park permit, costing $80, which allows entrance into a provincial park for the extent of a year. If you plan on doing a bit of eco-tourism in Canada, this could be a great deal.
