Chiricahua Becomes a National Park in the United States

Chiricahua National Monument in Cochise County, Arizona, was redesignated as Chiricahua National Park on 20 October 2026. The designation made it Arizona’s fourth national park and the 64th in the United States. The site covers approximately 12,000 acres and is known for volcanic rock formations, including tall spires and hoodoos.

From National Monument to National Park

The area was established as Chiricahua National Monument in 1924 by President Calvin Coolidge under the Antiquities Act. The Act, enacted in 1906, authorises US presidents to proclaim national monuments on federal lands to protect objects of historic or scientific interest. The Chiricahua National Park Act, signed into law by President Donald Trump, authorised the redesignation. US Representative Juan Ciscomani and US Senators Mark Kelly and Ruben Gallego sponsored the legislation. The House of Representatives passed it in March 2026, and the Senate passed it in September 2026.

Geography and Protected Features

Chiricahua lies in southeastern Arizona, within Cochise County. Its landscape includes distinctive rock spires and hoodoos formed by volcanic activity. The national park designation retained the site’s existing boundaries and provides protections for traditional cultural and religious sites. The law also provides for Tribal members to continue accessing those sites for customary uses. Chiricahua’s status as a national park places it within the United States’ national park system, which is administered by the National Park Service.

Park Administration and Access

National park designation can bring changes in visitation and management responsibilities. Local officials, including Willcox Mayor Greg Hancock, have anticipated increased tourism and visitor spending in the region. The National Parks Conservation Association and the Association of National Park Rangers have raised concerns about staffing and funding needs for the park and its infrastructure.
