Petroglyphs Provincial Park has been designated as a National Historic Site of Canada, showcasing the largest known concentration of Pre-Columbian era Indigenous rock carvings in Canada.

Petroglyphs is a day-use only park, open daily (excluding Mondays and Tuesdays in the spring and fall) from 10:00am to 5:00pm (no vehicle access after 4:00pm). It operates from the second Friday in May to the second Monday of October. While the park is officially closed and the entrance gate locked between mid-October and mid-May, it is possible to park at the gate and walked the access roads and trails. In the off-season the park is very popular with hikers, skiers, dog walkers and nature enthusiasts and the limited parking space is often filled by mid-morning (note that there is no parking on the shoulders of Northey's Bay Rd - CR 56 or adjacent Cheboutequion Drive). The western portion of the park's loop road is plowed in winter, but the eastern portion is not. Note also that while dogs are allowed to be on-leash throughout the park, they are not permitted at the Petroglyphs site.

During the operating season there are pit toilets available at the picnic areas and the Learning Place parking lots.
