This park stretches across 7,650 square km (2,954 square miles), containing nearly 2,500 lakes, 272 bird species, 45 species of mammals, and 50 species of fish and encompassing forests, rivers, and cliffs. The typical visitor is a hiker, canoeist, camper, or all three. But don't be put off if you're not the athletic or outdoorsy sort. About a third of Algonquin's visitors come for the day to walk one of the 17 well-groomed and well-signed interpretive trails or to enjoy a swim or a picnic. Swimming is especially good at the Lake of Two Rivers, halfway between the west and east gates along Highway 60. Spring, when the moose head north, is the best time to catch a glimpse of North America's largest land mammal. Getting up at the crack of dawn gives you the best chance of seeing the park's wildlife. Park naturalists give talks on area wildflowers, animals, and birds, and you can book a guided hike or canoe trip. Expeditions to hear wolf howling take place in late summer and early autumn. The park's Algonquin Logging Museum (late-June–mid Oct., daily 9–5) depicts life at an early Canadian logging camp.
