If you thought the Great Ocean Road was one long coastal drive, then this leg through the Otways may surprise you. Here the road heads inland, through shady rainforest with towering trees and fern gullies; it's home to a plethora of wildlife, most notably koalas. Cape Otway is the second-most-southerly point in mainland Australia (after Wilsons Promontory), and features a lighthouse that overlooks a beautiful, rugged coastline that's notoriously treacherous for shipping.
After Cape Otway the road enters the fertile Horden Vale flats, returning briefly to the coast at tiny Glenaire. Six kilometres north of Glenaire, a 5km detour goes to Johanna Beach, known for its massive surf; swimming here is not advised. From here the road heads inland again and north to the historic logging township of Lavers Hill.
The Otway region is home to the Gadubanud people; you can learn about their culture at the Cape Otway Lightstation.
