{"chart":{"slug":"fastest-growing-national-parks","title":"Which national parks grew fastest over 10 years?","takeaway":"Over the 10 years to 2025, Redwood's recreation visits grew 128%, the most of the parks compared. Hot Springs (76%), Kings Canyon (67%), Pinnacles (66%) and New River Gorge (66%) came next. Only parks with at least 100,000 visits in the first of those years are compared. A sudden one-year jump can come from a change in how a park counts visitors, not only from more visitors.","topic":"National parks","chart_type":"bar","ranking":false,"x_label":"National park","y_label":"Change in recreation visits over 10 years (percent)","unit":"percent","points_count":15,"source":{"name":"National Park Service, Visitor Use Statistics","url":"https://irma.nps.gov/Stats/"},"license":{"name":"Public domain (U.S. government work); source National Park Service","url":"https://www.nps.gov/aboutus/disclaimer.htm"},"data_as_of":"2025-12-31","updated_at":"2026-10-17T18:50:40.949Z","url":"https://chart.ly/charts/fastest-growing-national-parks","api_url":"https://chart.ly/api/v1/charts/fastest-growing-national-parks","csv_url":"https://chart.ly/charts/fastest-growing-national-parks/data.csv","image_url":"https://chart.ly/charts/fastest-growing-national-parks/image.png","embed_url":"https://chart.ly/charts/fastest-growing-national-parks/embed","credit":"National Park Service, Visitor Use Statistics, via Chartly (https://chart.ly/charts/fastest-growing-national-parks)","credit_html":"National Park Service, Visitor Use Statistics, via \u003ca href=\"https://chart.ly/charts/fastest-growing-national-parks\"\u003eChartly\u003c/a\u003e","average_label":null,"zero_axis":true,"data":[{"label":"Redwood","value":128.1},{"label":"Hot Springs","value":75.9},{"label":"Kings Canyon","value":66.6},{"label":"Pinnacles","value":66.2},{"label":"New River Gorge","value":66.1},{"label":"Indiana Dunes","value":60.3},{"label":"Big Bend","value":48.8},{"label":"Capitol Reef","value":47.5},{"label":"Acadia","value":45.1},{"label":"Joshua Tree","value":44.8},{"label":"Great Sand Dunes","value":44.4},{"label":"Kenai Fjords","value":43.4},{"label":"Great Basin","value":38.8},{"label":"Zion","value":36.6},{"label":"Glacier Bay","value":34.2}],"annotations":[]},"docs":"https://chart.ly/developers","terms":"Free to use with credit: wherever you show or quote a chart's data, name Chartly with a link to that chart's url (each chart's credit line does both) and credit its source as its license asks.","credit":"National Park Service, Visitor Use Statistics, via Chartly (https://chart.ly/charts/fastest-growing-national-parks)"}
