A tourism board for a popular national park is seeking to enhance accessibility for visitors with disabilities. The park offers various services such as guided tours, camping, and scenic viewpoints, but the staff has noticed that visitors with mobility and visual impairments are often unable to fully enjoy the park’s offerings. The tourism board is interested in assessing the park’s physical accessibility (e.g., pathways, restrooms, signage) and its online services (e.g., website, online ticketing). They want to determine the best method to carry out a comprehensive accessibility audit and implement improvements.
