Abstract. The Philippines has a diversely beautiful topography which is an awe-inspiring combination of mainland and thousands of smaller islands. But as to the development of tourism, there is still a large gap between the Philippines and other Southeast Asian countries with highly developed tourism. However, the Philippines takes "original ecology" as a unique way to attract tourists, which provides a solution to alleviate the fund pressure of the construction of tourism facilities, better meets the ecological protection requirements of the international community and provides a new development idea for other countries with less advanced tourism.
