North Head Geology and Migration Lab

North Head is where children can feel the coastline thinking on a larger timescale. The cliffs and headland show what happens when rock, wind, salt and water spend enormous stretches of time working on the same edge. Sandstone looks solid, but weathering keeps breaking it down. Little cracks widen, surfaces flake and the whole shape of the coastline slowly changes.

This is also one of the best places to talk about migration. High headlands give humans wide views, and they help explain why whales and seabirds use predictable coastal pathways. Animals moving long distances do not travel randomly. They follow routes linked to food, currents, safety and geography. At North Head, geology and biology are tied together in one big science lesson.
