Who doesn’t love things that are free, especially if those things involve a bit of a road trip? Our national park system has just the thing! Each year, about six times per year (depending on circumstances, of course), selected National Parks throw open their doors and welcome all comers. This makes for a budget-friendly adventure fit for families and adult travelers alike. Below are some of the national parks in New Mexico that offer free entrance days:

1. Aztec Ruins National Monument (Aztec)
725 Ruins Rd, Aztec, NM 87410, USA
Ena G./ TripAdvisor
Here live the roots of the Pueblo people. This monument, in the Four Corners area, lets visitors explore the ruins of a walled city built by the Ancestral Pueblo people in the 1100s. Though a "ruin," the site is remarkably well-preserved. Completely walled, the settlement has more than 400 rooms and a dozen kivas. The completely restored "Great Kiva" is the oldest and largest reconstructed kiva in North America. The self-guided trail around the site is about a half-mile long. Just 14 miles from Farmington, the Aztec monument is easy to reach by car.
2. Bandelier National Monument (Los Alamos)
Bandelier National Monument, New Mexico, USA
Pallav B./TripAdvisor
Bandelier National Monument is most well known for the cave dwellings dug into cliffs. Almost resembling an apartment building, the caves were dug from the volcanic tuff cliffs by the Ancestral Pueblo people who lived at Bandelier in the 12th Century. The monument spans 33,000 acres, but there is no way you can see it all. For the best ruins, take the trail into Frijoles Canyon. Also, climb the four wooden ladders to reach the Alcove House, a petroglyph-covered cave with a reconstructed kiva. Read more about exploring these ruins up close.
3. Capulin Volcano National Monument (Capulin)
Capulin Volcano National Monument, New Mexico 88418, USA

Capulin Volcano rises almost 1,000 feet above the surrounding landscape. However, don't worry, it is long extinct. If you have ever wanted to explore a volcano up close, here is your chance. You can drive right up the side and park at the rim. From there, a trail leads to the bottom of the crater. Aside from the majesty of the volcano itself, catching the scenic vistas is the "to-do" thing at Capulin. You can also check out the visitor center for ranger-led programs and a short film about the volcano.

4. Carlsbad Caverns National Park (Carlsbad)

Go underground at Carlsbad Caverns for an other-worldly view. This is another New Mexico must-do experience. The Big Room is the grandest cave of the 119-cave system. It is big enough to hold more than six football fields. Many consider it the most visually interesting, with features like the Bottomless Pit and Painted Grotto. Pro Tip: Hang out until dusk and catch the Brazilian free-tailed bats exit the cave in masse, in search of their evening meal. Before you go, check out more information about this beautiful, underground attraction.
5. Chaco Culture National Historical Park (Nageezi)

It's a little tough to get to Chaco Canyon. It's 70 miles from any town and the drive involves a long bumpy ride down a washboard road. Just chalk it up to part of the experience. Though remote by today's standards, Chaco was once a center for Puebloan culture. The ancient inhabitants had complex engineering and architectural skills. The excavated ruins on this site prove this out, with Chacoan "great houses," kivas, roads, and a mystifying geometric layout. If the history thing bums you out, this park also has hiking, biking, and even night sky programs. Learn more about these incredible ancient ruins.
6. Gila Cliff Dwellings National Monument (Silver City)
Gila Cliff Dwellings National Monument, 26 Jim Bradford Trail, Mimbres, NM 88049, USA

Gila is another national site that takes a little planning to get to. It's in the Gila National forest, at the edge of the Gila Wilderness. The 553-acre site contains the ruins of cave dwellings built by the Mogollon peoples between 1275 and 1300 AD. The dwellings are interlinked and built across five cliff alcoves. After you're done exploring the cliffs, look for hot springs in the area, too. The Lightfeather spring is easy to reach. It takes about 30 minutes to walk to from the visitor's center. At Gila, be sure to hike to this aboveground cave.
7. White Sands National Monument (Near Alamogordo)
White Sands National Park, New Mexico, USA

Since sand shifts with the wind, White Sands National Monument is never the same. Here, pure white gypsum covers 275 square miles, making it the largest gypsum dune field in the world. Unlike other types of sand, the gypsum crystals at White Sands don't get hot. The park opens early and stays open past sunset. White Sands is always breathtaking but the light at dusk and dawn amplifies the beauty. Check out some spectacular video footage of White Sands!

Look for free entrance days around holidays like Martin Luther King Jr. Day, Presidents’ Day, and Veterans’ Day. The National Parks Service also celebrates its birthday and National Public Lands Day with free park entrances. Keep in mind, not all parks participate in every free-admission day. Be sure to call the park before you plan your free trip. For more information, visit the National Park Service Free Entrance Day information web page.

National Parks to Visit in New Mexico

What are the best state parks in New Mexico?  

New Mexico is home to 35 amazing state parks. It’s far more beautiful than most people tend to give it credit for; they assume it’s a desert wasteland and skip it in favor of, say, Colorado – but they shouldn’t. New Mexico is amazing, and its state parks reflect this well. Some of our favorites include the amazing White Sands National Monument, which features some of the most amazing dunes in the nation and countless photography opportunities. It’s located at the northern end of the Chihuahua Desert and is well worth a visit to show you just how amazing the desert can be. Then there’s the world-famous Carlsbad Caverns National Park, which features 119 mapped caves and one of the most amazing cave systems on the continent – right here in little ol’ New Mexico. We also love Cerrillos Hills State Park, south of Santa Fe, for amazing views and great hikes, and Morphy Lake State Park, found in the eastern Sangre de Cristo Mountains, is home to a crystalline blue lake that you’ll never want to leave. Need more inspiration? Check this article out for some of our favorite underrated state parks in New Mexico. 

What are the best hiking trails in New Mexico?  

New Mexico is host to no less than 1,400 amazing hiking and biking trails. We’re not surprised; as underrated as this state tends to be, it’s definitely known for some of its amazing hikes, like the Williams Lake Trail, which can be hard or moderately challenging depending on which way you decide to hike it. Take Williams Lake Trail on its own and you’re in for 4.2 miles of good times and great lake views in a mountainous landscape. Branch off onto Wheeler Park Trail and head to the tallest point in New Mexico – an 8.5-mile trek – instead, though that hike is considered hard and should be attempted only by experienced hikers. We also love the Nambe Lake Trail, located in Santa Fe National Forest. This one is challenging and 6.7 miles long, but it leads through the amazing southern Rocky Mountains and is well worth the effort.
