From Darlington, there’s a two-hour loop walk to the Fossil Cliffs and the old brickworks. If you have more time (four hours return from Darlington), climb Bishop and Clerk (620m) for a bird’s-eye view while you eat your packed lunch on the exposed, rocky summit. Mt Maria (711m) is the island’s highest point; it’s a seven-hour return hike through the eucalypt forests from Darlington, with brilliant views over the island’s isthmus from the top.
