I assume you were talking the last second picture. Yes, it's in Gatineau Park. Park your car at O'brian Beach and take the trail. After a steep downhill and across the bridge, keep going about 5 minutes, you will get to a "T" intersection. Take the trail that has no sign . Walk for about another 5 minutes, you will get to the place, where is called Wilson Ruins. And that's the place.
