The Redpath Museum is on the beautiful McGill campus right in downtown Montreal. The museum is curated by McGill and is always free! It is a stunning building inside and out. The McGill campus itself is worth taking a stroll around in my opinion— really! Inside there are three floors that display everything from ancient Japanese culture and art to giant skeletons of dinosaurs like the t-rex. The museum is quiet and the ambience is really soothing. I've often taken my four year old here— he never tires and we always learn something new! Plus, it's free!
