Cultural tourism experiences include, but are not limited to, architectural and archaeological treasures, culinary activities, festivals or events, historic or heritage, sites, monuments and landmarks, museums and exhibitions, national parks and wildlife sanctuaries, and religious venues. It includes tourism in urban areas, particularly historic or large cities and their cultural facilities such as theatres, as well as tourism in remote, indigenous regions. In the twenty-first-century United States, national parks and a limited number of Native American councils continue to promote tribal tourism. The U.S. National Park Service has publicly endorsed this strain of cultural tourism, despite lingering concerns over exploitation and the potential hazards of ecotourism in Native America.
