Tosari District is one of the tourist villages in Pasuruan Regency that has potential ecotourism because it is the gateway to Mount Bromo National Park. There are protected areas with the socio-cultural values of the Tenggerese Tribe. Ecotourism is an appropriate concept because it prioritizes sustainability, environmental conservation, and the uniqueness of tourist attraction objects. Developing sustainable rural infrastructure is the key to inclusive development to improve the concept of Ecotourism, thereby increasing economic resilience and engaging community productivity. This study aims to analyze the development of rural infrastructure that can improve ecotourism management. This study uses a qualitative approach to identify problems that are closely related to the provision of the physical infrastructure to reduce disaster levels, infrastructure that can boost agricultural productivity, and social infrastructure that needs to be established for ecotourism purposes. The need for infrastructure development is translated into the provision of waste management, disaster protection infrastructure, and improvement of road and communication infrastructure. The concept of a cultural approach requires carrying out tourism operations and preserving the culture of the Tengger tribe.
