Achray Campground sits on the northern shore of Grand Lake in the eastern reaches of Algonquin Provincial Park, Ontario. The campground offers 45 non-electrical campsites along with a single lakeside yurt that sleeps up to six.

Facilities are considered primitive compared to other campgrounds in the park, though the site carries notable history — its stone park store was built in the 1930s by park rangers using stone quarried from the opposite shore of Grand Lake.

The campground serves as a trailhead for several hiking routes, including the interpretive Berm Lake Trail, the Jack Pine Trail, and the Eastern Pines Backpacking Trail, which leads to a waterfall on the Barron River.

It is also a popular launching point for canoe tripping into the Barron River system. Reservations can be made through Ontario Parks online or by phone.
