The main obstacles of ecotourism development are the lack of specialized guides and
the tourists‟ lack of appreciation of ecotourism. Environmental interpretation materials
have been provided in many national parks, but they are often of poor quality. Many
ecotourism resources still lack the readiness to attract and serve the more serious ecotourist.
Moreover, many tourists behave inappropriately at ecotourism sites. For
example, they are noisy and throw their garbage everywhere and show disrespect of
local or indigenous cultural values. It is very difficult for the entrepreneurs such as tour
operators and guides to control them as they have no real authority over the tourists.
