Bonnechere Provincial Park is a recreational park which offers camping, rustic cabins, sand beach with roped swimming area, and facilities such as showers, washrooms, recycling, gift shop.
The trails are well maintained and provide easy walking. The main feature of the park, aside from Round Lake, is the Bonnechere River. This river flows east from Algonquin Park, through Round Lake, Golden Lake, Eganville, Renfrew and empties into the Ottawa River east of Renfrew.
In Bonnechere Provincial Park old oxbows are features that are visible along the trails. The park is mostly forested consisting of White Pines, White Spruce, Large-toothed Aspen, and other species typical of the Great Lakes St. Lawrence Forest. The McNaughton Trail passes through conifers and mixed forest, wetland, passes oxbows and the banks of the Bonnechere River. Black-backed Woodpecker seems to be a permanent resident as it has been recorded in 30 years of breeding birds surveys. In 2010 it was heard between the road to the rustic cabins and the oxbow bridge. Other commonly heard birds along the trail are Broad-winged Hawk, Blue Jay, Hermit Thrush, Red-breasted Nuthatch, Yellow-rumped Warbler, Nashville Warbler, Magnolia Warbler, Swamp Sparrow and Purple Finch.
Bonnechere River Park connects BPP with Algonquin Provincial Park to the west.
