Along the way expect to see: the city's oldest surviving structure, built by convicts in 1828; iconic sculptures from across the ages; the City Hall; the General Post Office; Anzac square; two landmark Gothic Revival cathedrals; and a surprisingly illuminated toad.

All this plus puzzles, challenges, rest-stops at great bars and cafes and plenty of surprises.
