Fodor's Expert Review Sydney Mines Heritage Museum and Cape Breton Fossil Centre
Two affiliated facilities across the harbor from Sydney proper chronicle the area's prehistoric and more recent pasts. The mines museum, which occupies a small converted train station, surveys area history but focuses on Sydney's coal-mining connection. Displays at the fossil center include 300-million-year-old specimens from the Sydney Coal Fields. The fossil center's curator leads two-hour fossil-hunting field trips, by reservation, on Tuesdays and Thursdays at 10 am; you'll need your own transportation to the trip's starting point.
