St  Lawrence Islands

The first national park of Canada east of the Rocky Mountains, St. Lawrence Islands National Park is formed by all or part of 24 islands and more than 80 shoals and islets in the Thousand Islands region of the St. Lawrence River. The park was established in 1904 as a response to concerns of the locals about preservation of natural beauty on the majority of the Thousand Islands which were privately held. Just a few hours of ride from Toronto you can find the rocky islands, windswept pines, and refreshing waters which are just a perfect place for vacation with the flavour of the northern wilderness. Place is also the traditional summer home to Haudenosaunee and Mississauga Anishinaabe whose historic summer sites are in interesting contrast to the rugged islands with spectacular animal inhabitants, turtles and eagles including. Presence of the Great Lakes makes climate in the area moderated by the effect of a "heat sink". Services are offered May to mid-October, while the park is open-year round.

The Thousand Islands were formed ten thousand years ago by a granite chain of more than a thousand mountains from retreating glaciers scraping sediment of the landscape around present Kingston. Today, the area contains winding necklace of river jewels, whispering marshlands, rock outcroppings and a rich diversity of plant and animal species which attracts visitors from around the globe to admire beauty of 24 islands, 129 islets, and 8 mainland tracts known as St. Lawrence Islands National Parks.

With only over 24 square kilometres, St. Lawrence national park is the third smallest national park in the country. Its area takes over 80 kilometres of the upper St. Lawrence River. Substantial part of the park is naturally accessible by boat only. Park's visitor centre can be found at Mallorytown on the mainland.

Many species found here occur nowhere else in Canada, most notably the pitch pine. Prescribed burns in the park promote its regeneration, otherwise at risk in the province. The variety of habitats and vegetation is reflected by the faunal diversity. More than 30 species of reptiles and amphibians (only Georgian Bay Islands National Park boasts greater diversity of them), 200 species of birds, 80 species of fish, and 50 mammal species can be spotted in the area. Some of the larger islands are inhabited by deer, red fox, and coyote. Black rat snakes, wild turkey, and osprey are species whose population numbers are monitored in the park. Other notable examples of species common in the area, but rare in the rest of Canada, are rue anemone and bittern. You can still see deerberries on some islands.
