An expanded guide to the best places in Ontario to connect with the natural world.

The best-selling 100 Nature Hot Spots in Ontario now features 10 additional destinations. This reader-friendly guide explores the remarkable splendor and diversity of the province, from its soaring clifftops, subterranean caves and thundering cataracts to the province's tallest white pine, the oldest rocks on Earth and the warbler capital of North America.

The guide is organized by region, and each destination includes a descriptive profile illustrated with color photographs and at-a-glance information about special features and contact details. Regional maps showcase locations. Some of these hot spots are surprisingly close to towns and cities, some are hidden urban treasures, and many are ideal for a day trip.
