The local community was contributing to ecotourism development through respecting their culture, protecting nature and by involving in much tourism related activities.

Regarding to nature, 48% of sample respondents reported the higher respection of female to nature than male, whereas, 46% of respondents said male. Moreover, 84 and 79% of the respondents said that married people give more value for both nature and culture, respectively. Of the total respondents, 50% said illiterate have more respect to nature but the remaining said the literate ones.
