The relationships between cities and tourism are much wider than the scope of this chapter. Much tourism clearly occurs outside cities, but the importance of cities is easily argued and only the most relevant aspects of these interactions will be considered here. Most tourists originate from cities and most either seek out cities as holiday destinations in themselves or use services or visit attractions located in cities while staying on holiday elsewhere (Page 1992, 1995; Berg et al. 1995; Borg et al. 1996; Law 1993, 1995). However, more directly relevant for the purpose here is to specify those aspects of cities that contribute towards a tourism that not only occurs in cities but is also distinctly urban. It is these characteristics that relate the specific activity of urban tourism to the distinctive forms and functions of cities and underpin much of the discussion of policy.
