A Christian Ministry in the National Parks (ACMNP) is a grassroots ministry that began in Yellowstone National Park in 1951 with the dream of providing Christian community for the people working, living, and visiting the parks. ACMNP accomplishes this by helping students find paying jobs and housing in the parks. Upon arrival in the parks, ACMNP team members serve with ACMNP by leading interdenominational worship services, Bible studies, community building activities and park stewardship projects.
