Achray Campground, situated on the northern shore of Grand Lake in the northeastern corner of Algonquin Provincial Park, serves as Access Point 22 for backcountry paddling and is also a developed car-camping destination.

The campground offers 45 non-electrical campsites and is notably more primitive than other park campgrounds. A historic stone building on site was constructed in the 1930s by park rangers using stone quarried from the opposite shore of Grand Lake.

Grand Lake itself is the primary backcountry launch point in the area, with Carcajou Bay and its campsites reachable within a few kilometres by canoe.

The Eastern Pines Backpacking Trail and the shorter Berm Lake interpretive trail are both accessible from the campground. Nearby attractions include the Barron Canyon, High Falls, and a popular sand beach with views over Grand Lake.

The access road beyond Sand Lake Gate is unpaved and can be rough.
