Анотація: (English) Every year, more than 300 million people visit U.S. national parks. Managing such large numbers of visitors without harming the environment requires specific solutions, and over the past century, these solutions have been compiled into a body of documented best practices. This article examines which approaches have proven effective, where unexpected consequences have arisen and what practical lessons can be learned from this experience by managers of protected areas. The role of travel agencies is also considered: data from three independent Ukrainian agencies showed a reduction in the number of incidents during trips of between 47% and 58% following the introduction of mandatory pre-departure briefings for clients. The article concludes that a combination of regulatory, educational and technological measures, aligned with continuous monitoring of the actual state of ecosystems, is key. The pre-departure preparation methodology developed by the author, formalized as the CXC-360 Visitor Preparation Framework, represents a scalable model applicable beyond the Ukrainian context.
