A short 1.5 km, but popular and challenging loop takes hikers up to the cliffs overlooking the Barron Canyon and River. Caution is required along cliff edges, which are not fenced from the trail.

In the northeast corner of the park, Grand Lake provides backcountry campsites on its southern shore. From Grand Lake, you can also access Carcajou Bay to see waterfalls flowing over granite, or portage to the Barron River and Barron Canyon. Achray Campground is located here, so visitors can combine daytime canoeing with car camping, in a more remote location than the Highway 60 corridor.
The park's largest lake, with rentals and access off Highway 60. The expanse of the lake and wild shorelines create a scenic route for canoeing, but also provide little shelter from strong summer winds. Some paddlers time their departure to avoid strong winds, or use a motorboat water taxi to skip Opeongo completely. Many backcountry campsites dot the shores of each arm of the lake.
An outdoor pathway and reception building details the history of logging in Algonquin Park, including outdoor exhibitions of historic and modern equipment. The buildings are open in late spring to early autumn, but the outdoor trail and some exhibits are accessible in winter.
An easy 1.5 km flat loop, with sections of wooden boardwalk, takes walkers and birdwatchers across Sunday Creek into the bog.
About 450 million years ago, a large meteorite created a "bowl" in the hard rock of the Canadian shield, 3.8 km wide and about 427 m deep. Evidence suggests that the area was submerged under water at the time; if not, the force of the impact would have likely knocked over nearly every tree in the park. In the millions of years since, erosion and glacial movement has filled most of the crater, so the forest and small lakes at the bottom are now only about 60 m below the road. An observation platform provides a panoramic view from a hill along the road. A self-guided interpretative walk explains interesting points along the Brent Crater Trail, a 2 km loop, or about 3.2 km if you include a detour to Tecumseh Lake.
An easy 3 km looping trail through an area that was logged in the 1880s. Today, the remaining white pines have matured, and the area is one of the best preserved old growth white pine forests in the park.
