4. We know, from pictographs in the area, that Native Americans lived on this land starting from 12-14,000 years ago. It is believed that they used the caves near the surface long before they were “discovered.”

5. In the 1880s, people didn’t go into the caves to admire them. Instead, they were there to mine for bat poop! Apparently, guano is a powerful fertilizer.

6. Some people are under the impression that James (Jim) Larkin White was a cowboy who stumbled upon the caves by chance. He was actually a guano miner who explored the far reaches of the caves in his downtime. It is up for debate who first found the entrance to Carlsbad Caverns.

Where can I hike to a cave in New Mexico?

Carlsbad Caverns isn't the only place where you can explore caves in the Land of Enchantment. You can actually hike to a cave in New Mexico at El Malpais National Monument! Situated about 35 minutes outside of Grants, this rugged destination features underground lava tubes created eons ago by molten lava flowing beneath the surface. There are a total of five tubes you can explore and they're all fairly beginner-friendly. Some degree of rock scrambling, climbing, and squeezing through narrow passageways is required, but you don't, by any means, have to be an expert spelunker. Just remember to bring two light sources, plenty of water, gloves, and layered clothing!

Can I hike to abandoned places in New Mexico?

If you've never taken a hike to abandoned places in New Mexico before, the Mexican Canyon Trestle Trail is sure to ignite the adventurer within you. This historic rail-to-trail conversion in charming Cloudcroft leads to a now-defunct railroad bridge known as the Mexican Canyon Trestle. Located on the National Register of Historic Places, this 323-foot-long bridge was part of the Alamogordo & Sacramento Mountain Railroad, which provided the sole means of access to the town until the 1940s. The 1.2-mile Mexican Canyon Trestle Trail is short, easy, and incredibly scenic, leading to a viewing platform that overlooks the trestle.

What are the most beautiful hikes in New Mexico?

One of the most beautiful hikes in New Mexico is, without a doubt, the Dripping Springs Trail. Located inside the Dripping Springs Natural Area near Las Cruces, this 2.7-mile trek is situated at the base of the Organ Mountains, whose towering peaks rise above you as you hike. Not only does the trail showcase stunning views, but it also leads to several unique historical landmarks, including an old resort and a camp that once serviced it. You'll also come across Dripping Springs — the trail's namesake — which is a natural spring that features a gorgeous waterfall.
