Luna Park, Melbourne
In keeping with the Edwardian theme, Luna Park exudes a tacky turn-of-the-century thrill seeking. It is strongly reminiscent of its forebear on Coney Island, New York. It was built in 1912 and still retains its original roller coaster - the Scenic Railway - which is the oldest ride in the world still in operation. Despite its kiss-me-quick aura, it's a small part of Melbourne's history, and a St. Kilda institution - everyone remembers it from their childhood.
This is a typical family funfair park. The admission is free, and the rides cost $7 (November 2005 prices) each or you can purchase an unlimited ride ticket for $33.95 (adult fare). The rides are pretty tame compared to those you would find in larger theme parks. The park doesn't open everyday - check the website for the opening times.
For those who like theme parks with rides and games then Luna Park is the place. Open every weekend.
