The tuart is a type of eucalypt that only grows on coastal limestone 200km either side of Perth, and this 20-sq-km strip squeezed between the Bussell Hwy and the Indian Ocean is the last pure tuart forest left. An alternative route to Busselton from Bunbury leads through the shade cast by these giants, some more than 33m tall.
Turn off the highway at Tuart Dr, 4km southwest of Capel. After 11km, turn right into Layman Rd for Wonnerup House, a National Trust homestead (1859). Continue past the seaside village of Wonnerup and follow the coast to Busselton.
