- The tourism development should assist conservation, supplement local people's incomes, bring new use and value to historic structures and enhance reclamation of derelict land.

- Planning, designing and siting of tourist developments should be compatible with and, if possible, enhance the local landscape

- Control of tourism should remain as far as possible in local hands; this control and the ensuing benefits should contribute to environmental conservation and enhancement.

- Tourism investment should support the local economy and encourage a steady dispersal of activity, so avoiding congestion and minimizing impacts

- The tourism industry should actively assist the understanding of both the local populations and the tourists - information, interpretation, and education.
