“…However, the entry fee amount must be evidence-based and match WTP for both domestic and foreign visitors (Shahabuddin, 2009). Earlier studies have concluded that most visitors are ready to pay to enter to frequently visited natural areas (e.g., Abala, 1987;Depondt and Green, 2006;Baral et al, 2008;Svensson et al, 2008;Reynisdottir et al, 2008;Uyarra et al, 2010;Peters and Hawkins, 2009;Thur, 2010;Gupta and Mythili, 2011;Chung et al, 2011;Dhakal et al, 2012). Many studies, however, showed that visitors WTP in several cases are higher than the existing fee (such as Riley et al, 2006;Thur, 2010;Asafu-Adjaye and Tapsuwan 2008;Peters and Hawkins, 2009;Szell and Hallett IV 2013;Tyrväinen et al, 2014;Baral and Dhungana, 2014;Vincent et al, 2014).…”
