An extraordinary array of national park units — 34 in all, which include national monuments and historic sites in addition to parks — blanket Arizona from border to border. This is where we keep our most exquisite scenery, our storied history and wide-open spaces. Parks range from the volcanic sprawl of stone hoodoos crowning Chiricahua National Monument to the gaudy badlands of Petrified Forest National Park to the miles of seductive shoreline at Glen Canyon National Recreation Area. And there’s even a certain canyon known to steal hearts and alter lives. 

Last year brought cutbacks to staff and funding, putting a strain on our national parks. Let’s show our support in 2026 by rediscovering these crown jewels. To get you started, here are 10 of the best hiking trails in Arizona’s national parks. 

Organ Pipe Cactus National Monument, Victoria Mine Trail

Starting from the campground, this 2.2-mile trail rambles across a rolling desert plain to the foothills of the Sonoyta Mountains. The trail highlights the range of cactus species the park protects as it dips in and out of arroyos on its way to the remains of the Victoria Mine. Founded in the 1890s, the Victoria produced enough gold and silver to keep men digging for decades in this lonely place. Rusting equipment lies scattered about and the ruins of the company store still stand. Return the way you came for a 4.4-mile outing or continue on one of the other trails connecting here.

Tonto National Monument, Lower Cliff Dwelling

Even without the big payoff at the end, the hike to the Lower Cliff Dwelling makes a gorgeous desert outing. The paved trail twists up the slope in a series of curves. Signs are posted along the path providing information on native plants and animals, and a good reason to pause and catch your breath. As you climb, the views across the basin widen. What starts as a slivered peek grows into a broad panorama with a bristling foreground of saguaros and a distant backdrop of mountains framing the blue of Roosevelt Lake. At the top of the trail, a rough stone house fills the eye socket of a cave. Built more than 700 years ago by people of the Salado Culture, it contains about 20 rooms. A docent is on hand to answer your questions.

Chiricahua National Monument, Heart of Rocks Loop

Hidden in the southeastern corner of the state, Chiricahua National Monument is a place of remarkable beauty, sheltering an array of sculpted stone. Massive columns, slender spires and impossibly balanced boulders loom above the timber. The skyline seems built from the splintered remains of ancient castles. An interconnected network of trails provides visitors with several options. The short loop through Heart of Rocks is the craggy core of the park, where you’ll find the most spectacular formations. Easiest route to reach Heart of Rocks is via a trio of trails: Ed Riggs, Mushroom Rock and Big Balanced Rock. The Heart of Rocks twists through a weird stone garden filled with formations like Thor’s Hammer, Duck on a Rock, Camel’s Head and Totem Pole. Mileage totals 7.3 miles round-trip.

Saguaro National Park, Hugh Norris Trail

Unlike the cruel slog of most summit hikes, the Hugh Norris Trail (10 miles round-trip) is an airy jaunt that keeps your noggin on a swivel while you gawk at one sweeping view after another. There are some steep pitches but that only sweetens the deal, making it feel like you earn the expansive vistas, among the best in Tucson. Set in Saguaro National Park West, the trail carves a route through classic Sonoran landscape to the top of 4,687-foot-high Wasson Peak. The trail starts out on a cactus-studded bajada and switchbacks upwards to snag a rocky ridgeline. From there the trail angles towards Wasson, hugging first one side of the high shoulder and then the other.

Grand Canyon National Park, South Kaibab Trail

Screamingly steep, shade-less and sun-beaten may not sound like an endorsement but it’s what makes the South Kaibab astounding. Most canyon trails follow a fault line limiting range of vision. But Kaibab is a torpedo, launching from the South Rim and chasing a ridge down and out across the canyon. In just under a mile, the canyon cracks open wide at aptly named Ooh Aah Point. At 1.5 miles you reach a comfy plateau called Cedar Ridge, the most popular day hike option. Only the fittest hikers should continue to Skeleton Point atop the Redwall Limestone, offering your first glimpse of the Colorado River. This makes for a 6-mile strenuous round-trip.

Details: Park admission: $35. 928-638-7888,www.nps.gov/grca.

Petrified Forest National Park, Blue Mesa Trail

This 1-mile loop appears to wind its way through the suburbs of the moon. The path from the parking area starts out paved but switches to gravel as it makes a sharp descent into a small basin wrapped in an otherworldly array of bluish bentonite clay badlands. These are haunting hills streaked with a soft, mournful color palette. Sprinkled amid this lunar landscape is a colorful collection of petrified wood. Watch for pedestal logs, remnants of ancient trees perched atop a crumbly stand of thick clay as if on display. Numerous plant and animal fossils have been found in the layers of Blue Mesa.
