Arizona is more than the Grand Canyon. Here are 5 other national park sites to visit

The National Park Service will offer free admission to all of these sites throughout the year.

Arizona is well-known for the Grand Canyon National Park, which sees millions of visitors from all over the world every year.

But our state has much more than just this one park. Arizona is home to two other national parks—Petrified Forest and Saguaro—as well as over a dozen national monuments, memorials, historic sites, and more.

On certain days, the National Park Service (NPS) offers free admission to these sites. Here’s the list of the remaining free park days in 2025:

• June 19: Juneteenth
• July 16: Bureau of Land Management’s Birthday
• Aug. 4: Anniversary of the Great American Outdoors Act
• Sept. 27: National Public Lands Day
• Oct. 27: First Sunday of National Wildlife Refuge Week
• Nov. 11: Veterans Day

Here are some spots that can satisfy the desire to get outside—just be sure to check the website or call ahead to check for any closures before heading out.

1. Fort Bowie National Historic Site

Fort Bowie, about 90 miles east of Tucson, represents a quarter-century of conflict between the Chiricahua Apache tribe and the US Army in the late 1800s, according to the NPS. A 1.5-mile hike brings visitors to a visitor center and the ruins.

The site also includes a cemetery that was active before and after the fort was in use. According to the NPS, 22–32 bodies may remain.

The fort is also a good place to see wildflowers in the spring and summer. More than 600 plant species have been recorded there.

2. Montezuma Castle National Monument

For those looking for something more near the Valley, Montezuma Castle is about an hour and a half drive north of Phoenix. The castle, which the NPS describes as a “20-story high-rise apartment,” is built into the side of a limestone cliff.

The Sinagua people lived in the area for over 400 years. After the site was established as a national park in 1906, visitors could climb ladders to access parts of the monument. But this caused damage to the structure, and public access was cut off in 1951.

3. Organ Pipe Cactus National Monument

For a taste of the border, head to Organ Pipe Cactus National Monument, about 100 miles west of Tucson. The site, which is also an International Biosphere Reserve, features 30 species of cacti in addition to its namesake.

There is evidence that humans lived there at least 1,600 years ago. The Hohokam people inhabited the area for about 1,450 years, and several miles of their canals are still visible in the park.

The area has over a dozen hiking trails and two campgrounds. However, multiple roads are closed for public safety. Check the website before going to plan your route.

4. Sunset Crater Volcano National Monument

While many people associate Flagstaff with Humphrey’s Peak, there’s another big sight to behold there—Sunset Crater Volcano.

The 1,000-foot volcano erupted in 1085 and set off a plume of fire 805 feet tall. It took 400 years for vegetation to return to the area.

There is another volcano nearby, too: the Lenox Crater Volcano. It is much older than Sunset but only 300 feet tall.

Both volcanoes are included in the national monument, which was established in 1930.

5. Tonto National Monument

For those looking to be near water, Tonto National Monument is located right next to Roosevelt Lake, about a two-hour drive from Phoenix.

Visitors can see two cliff dwellings in an area inhabited by the Salado people from 1250 to 1450. There is still one complete room left, with walls built from stone and mud and saguaro ribs and clay used for the roof.

The Woodbury Fire in 2019—one of Arizona’s largest wildfires in state history—burned 88% of the national monument’s land, but neither of the structures were damaged.

While the monument’s visitor center is open 8 a.m. to 4 p.m., visitors must begin their hike to the Lower Cliff Dwelling by noon. The trail can close due to excessive heat or lightning. Hikers can only access the Upper Cliff Dwelling via guided tour, and those are offered November–April.
