Families can explore accessible lava tube caves like Big Skylight Cave, hike across otherworldly aa and pahoehoe lava flows, and climb extinct cinder cones that rise dramatically from the desert floor. The monument's unique geology creates natural ice caves that stay frozen year-round, while its pristine night skies offer some of the darkest stargazing in the Southwest. What truly sets El Malpais apart is how it combines raw volcanic drama with living cultural history—ancient Zuni-Acoma trading trails still cross the lava flows, showing how Indigenous peoples navigated this challenging terrain for over 5,000 years.
Junior Ranger Program at El Malpais National Monument
The Junior Ranger program at El Malpais challenges young explorers to investigate volcanic features, learn about desert adaptations, and understand how people have lived in this harsh environment for thousands of years. Kids complete activities focused on geology, archaeology, and desert ecology while earning their official Junior Ranger badge through hands-on exploration of this fascinating volcanic landscape.
- Exploring accessible lava tubes and ice caves
- Learning about volcanic formations and how lava flows shaped the land

Best Ages for El Malpais National Monument
Ages 6 and under
Young kids complete just 4 activities plus the ranger chat, making this very manageable for short attention spans. The animal hide-and-seek and safety activities work perfectly for this age group, while the Monument Bingo gets them actively exploring. The volcanic geology activities might need parent help, but the hands-on exploration keeps little ones engaged.
Ages 7-9
This age group completes 6 activities and typically loves the lava tube maze and constellation connect-the-dots challenges. The fact-versus-opinion section helps develop critical thinking skills, while the desert word search reinforces vocabulary they're learning about volcanic features. Kids this age can handle more of the scientific concepts about how lava flows formed the landscape.
Ages 10-12
Older kids complete 9 activities and dive deeper into the monument's complex geology and cultural history. The hypothesis-building section about environmental changes challenges them to think like scientists, while the explorer journal writing lets them imagine crossing the lava flows themselves. This age group typically finds the cultural connections between Ancestral Puebloans and modern Zuni and Acoma communities especially fascinating.
Planning Your Visit
Getting There
The visitor center sits just off I-40 at Exit 85 in Grants, with excellent highway access for any size vehicle. No roads cross the monument itself—you'll need to drive Highway 117 south for eastern features like La Ventana Natural Arch, or Highway 53 north for El Calderon Trail and Bat Cave. Most families find the visitor center makes an ideal starting point for understanding the monument's layout before heading to specific trail areas.
Van & RV Notes
The visitor center parking lot accommodates Sprinters easily but can get tight for larger RVs during busy periods—arrive early morning for best positioning. No camping exists within the monument, but El Morro National Monument 23 miles west offers a small campground that handles bigger rigs, and Grants provides full-service RV parks with hookups. Highway 117 and 53 access roads handle any size vehicle, though some trail parking areas work better for smaller rigs.
Best Time to Visit
March through October offers the most comfortable hiking weather, with spring wildflowers and fall colors enhancing the dramatic black lava landscapes. Summer brings spectacular bat flights from Bat Cave but also intense midday heat—plan early morning or evening activities. Winter visits can be magical when snow caps the cinder cones, and the ice caves become even more impressive, though some higher elevation trails may be icy.
How Long to Spend
Plan a full day to truly experience El Malpais, splitting time between the educational visitor center exhibits and outdoor exploration. Most families spend 2-3 hours on trails like El Calderon or Lava Falls, plus time for the Junior Ranger program completion and ranger chat.
Don't Miss
The bat flight spectacle at Bat Cave during summer evenings absolutely mesmerizes kids—thousands of Mexican free-tailed bats spiral out of the lava tube in a living tornado that can last 45 minutes. Walking inside Big Skylight Cave provides an unforgettable underground adventure where families can see how lava tubes formed and spot the unique formations described in the Junior Ranger booklet.
Fun Facts for Kids
The lava flows at El Malpais are so young that some formed just 3,000 years ago—meaning Ancestral Puebloan people witnessed these volcanic eruptions
El Malpais contains both aa (AH-ah) lava with sharp, jagged surfaces and pahoehoe (pah-HOY-hoy) lava with smooth, ropey textures—kids love learning these Hawaiian names
Ice caves within the monument stay frozen year-round because cold air sinks into the lava tubes and can't escape, creating natural refrigerators
Mexican free-tailed bats from Bat Cave can fly up to 99 mph, making them among the fastest flying animals in the world
