An interesting question came up yesterday, what sort of good bushwalks can you do, that are accessible by train? We are assuming day-trips; back the same day. My first thoughts – as I said where The Dandenongs: Belgrave Station (where Puffing Billy departs from). I’ll update this later when I work out what walks go from there.
Another idea may be a country bus trip or combined train/bus trip. Time for some research.
