I am planning on driving from Melbourne to Kangaroo Island Oct. 17-21. The first night I was planning on staying in Apollo Bay. I'd like to do a night walk in Melba Gully to see the glow worms. Do I need to be on a tour? I'd also like to do the Otway Fly Tree Top Walk. Would it be better to spend the night in Lavers Hill? Second night in Warrnambool. 3rd night Mt Gambier. What is the fastest, most interesting way to go from Mt. Gambier to Cape Jervis to get the ferry to Kangaroo Island? Where should I spend the 4th night before driving to the ferry?
