This research attempts to present the notion of understanding through the empirical studies on environmentally responsible behaviour for strategies development with an emphasis on the role of facilitating conditions. A total of 263 usable questionnaire responses were collected for data analysis. The major findings show that environmental concern and environmental knowledge are important for environmental attitude in order to cultivate the environmentally responsible behaviour among tourists. Conversely, environmental facilitating conditions are directly related to environmentally responsible behaviour instead of having the moderating effect on environmental attitude. This study contributed in reassuring the tourists' participation in the environmentally responsible behaviour with commitment in environmental concerns and interest in knowledge towards environmental and sustainability issues while visiting natural sites.
