Geology & Discovery.
Craigleith Provincial Park's flat fossil-bearing limestone shelves extend into Georgian Bay along the south shore between Collingwood and Thornbury — Ordovician shales famous for trilobite fossils. Scenic Caves works the same Niagara Escarpment limestone in vertical form a short distance inland: fissure caves, ledges, and crevices in dolostone roughly 450 million years old, on a site within the UNESCO Niagara Escarpment Biosphere.
The brief.
Collection of fossils, plants, or other natural objects is prohibited at Craigleith Provincial Park under Provincial Parks rules — the experience is interpretive viewing, not collecting. The shoreline shelves are accessible during the park operating season (typical mid-May through Thanksgiving).
Scenic Caves is a privately operated attraction with seasonal programming and admission; the cave-and-cliff trails are walkable for most fitness levels with stairs and tight passages in the cave sections. Together they cover both the shoreline and cliff-edge geology of the south Georgian Bay escarpment edge.
