Overview:
This backpacking route explores a long chain of small volcanic cinder-cones and finishes with a crossing of the El Malpais (“Bad Country”) National Monument on the the dramatic Zuni-Acoma Trail. It features desert grasslands, juniper and ponderosa forest, cinder cones, lava tubes and the opportunity to dance the Scoria Shuffle. This hike could be done as a loop that includes a 20 mile walk on NM-117 (paved). Most hikers will prefer to set up a shuttle or to hitch-hike the paved section.
Driving Directions:
- From Interstate-40, west of Albuquerque, take exit 89 signed for NM-117 East / Quemado.
- At the end of the exit ramp turn onto NM-117 East. The initial direction is actually south; west-bound drivers will turn left and and east-bound drivers will turn right.
- After 14.9 miles on NM-117 turn right into the Zuni-Acoma trailhead. There is a brown Forest Service sign for the trailhead on NM-117. If you are setting up a shuttle then leave the first car here.
- After 19.2 more miles on NM-117-E turn right onto County Road 42 (dirt). The junction is signed. You can thank your driver and stop hitching when you reach this corner.
- In less than 0.1 miles on County Road 42, besides an information kiosk (that is, a signboard) on your left, park the second shuttle car.
A sign at the start of County Road 42 warns that this road is unusable when wet. Judging from the deep ruts on this date, that sign is not exaggerating.
Trailhead:
Apart from the information posted on the kiosk there are no services at either the Zuni-Acoma trailhead or on Co. Road 42. The CDT leaves from the east side of the Co. Road 42, across the road from the kiosk. Look for cairns or the white and blue plastic tags that mark the trail.
On this route the trail bears northwest, then north, northeast and southeast. All of this meandering is simply described as “north” in the text below.
Data:
Map note: my GPS unit is still misbehaving. The above map is not a GPS-measured track. Instead, it is a “route” traced from the CDT map on Caltopo. The line traced on this map may be somewhat distant from your actual position in the wilderness!
Distance between trailheads: 55.8 miles

Hike Description:
From the kiosk on County Road 42 find the trail and follow it as it slowly diverges away from the road. This is open desert grassland and the trail usually leaps out at you. But, setting a major pattern, the tread will occasionally play out. Sometimes it simply sinks into the grasses and at other times it weaves into cattle paths that are much better defined than the official trail. Look for cairns. At 1.2 miles from the trailhead the trail arrives at the edge of lava flow. Initially the trail skirts to the left, but soon nerves-up and leaps onto the black and convoluted surface. Bobbing east, ducking north, swerving west and even veering south, the trail tracks lava tubes, chases lava crevasses, mounts lava mounds and dives lava depressions. The last of these can be loess-filled and grassy, but scoria still protrudes above the soil. Watch your footing! That’s hard, because you must also watch constantly for cairns, your only guide across this trackless terrain.
At about 2.2 miles the trail leaves the lava and regains the grassland. The pace picks up as the tread improves. At roughly 5 miles from the trailhead you will see a windmill to the south (on your left for north-bound hikers). On this date the mill appeared to be in good repair and was spinning – there might be some water there. The trail swoops across shallow depressions and threads rocky outcrops, but on balance it gently rises. Very large cairns are placed off the trail on the top of the higher knolls. These may be intended as beacons for the lost. At about 10 miles, nearing the Cerro Brillante cone, a juniper forest makes a tentative first appearance.
The tread swings southwest to contour around the small cone adjacent to Cerro Brillante. It then contours north and gains a small amount of vertical (that alarming spike shown in the elevation profile at 12.7 miles). Aside from the scoria underfoot this is very pleasant walking. Ponderosa pines offer gratifying shade. The woodlands are open. Deer, elk and cattle regard you with dark suspicion. At 13.3 miles cross a faint two-track and look to your left to find a water tank made of an old tractor tire. (It is at several hundred yards off-trail). On this date the water in the tank was pretty good, although green enough to encourage careful filtering.
The tread bumps upward on the flanks of the next cinder cone and then descends to the plain that will lead to the cone beyond, creating a new pattern. In this way you pass Cerro Colorado (Red Hill), Cerro Negro (Black Hill), Cerro Chatito (Dawn Hill, maybe?) and Cerro Chato (Flat Top Hill? – it is a cratered cone with a huge breach in its northern wall). The trail comes its high point on the flanks of Cerro Lobo (Wolf Hill). The trail is nowhere steep and the ponderosa offer numerous and comfortably shaded rest spots.
Camping between the cinder cones is easy. The conifers put down a lot of duff and level ground is abundant. Beyond Cerro Lobo there is a scattering of very small cones, often hidden by the forest. Then then CDT climbs the flanks of a second cinder cone dubbed “Cerro Negro” and descends to a crossroad at 24.7 miles. Watch for it! If you go off-trail, 0.5 miles to the east along the road, then you will come to a metal tank. On this date the tank had very good water in it. The regulator looked broken – it is possible that the tank has water only when the rancher has recently activated the pump! Return to the trail and continue north.
The trail, which has been heading almost due-north, now bends to the northeast. Passing Cerro Leonides (Lion Hill), Cerro Americano and Cerrito Comadre (Midwife Hill?), the trail returns to County Road 42 at mile 30.2. Follow the road north (go left if you are north-bound). But, if you happen to be short on water, then first turn right onto the road and walk about 200 yards to an earthen water tank. On this date it was extremely shallow and muddy – but it could be a life saver.
The CDT stays on County Road 42 for the next 5.7 miles. This seems like an odd trail-engineering decision. Soon, however, you come to to a region where the terrain on your right is paved with shattered and knife-edged lava; the reason for staying on the road becomes evident. Towards the end of the road, just past Cerro Bandera (Flag Hill), watch for a second earthen tank on the left side of the road. On this date the tank had barely an inch of water in it, but the water was exceptionally clear. County Road 42 ends at a T-intersection with NM-53, which is paved. Go east (right for hikers going north) on NM-53. At 37.5 miles from the trailhead you regain the signed top of the continental divide.
The road-walk ends at the El Malpais Information Center, 39.6 miles from the trailhead. The CDT goes into this complex and passes on the west side of the eastern-most building. On the east side of this building is a water faucet. An attendant at the complex said that hikers can use that faucet. There is every conceivable luxury: picnic tables, clean water and even a trash receptacle! Make a meal here because there is no water for the remainder of this hike. Camel-up, fill your bottles and go to the other side of the building to regain the tread. Oddly, this tread gets on top of an earthen berm and stays there for more than a mile. Is it an old railway? An abandoned aquecia? It is hard to say. Past the berm the tread becomes entirely sketchy. The ground is piled with scoria and in many places there is no tread. It becomes routine to stop and scan (and rescan) the surrounding woods to find that next cairn.

At 41.8 miles, on ground characterized by brown dirt, brown grass and brown rock, come to a T-intersection with a trail that has been covered with crushed white limestone. Suddenly, almost surreally, you are presented with a foot path that could not be more obvious. Turn left and enjoy this short break from navigational challenges. Those challenges return when the trail brings you to a trailhead boasting vault toilets. Go left around the toilets, where the trail regains its now-you-see-it, now-you-don’t nature. The trail jukes and jives as it winds its way around huge, winding, and partially collapsed lava tubes. Give yourself extra time in this leg of the trip, the footing is an authentic challenge.
Come to the last of the cinder cones, Encerrito, at 47.6 miles from the trailhead. This is the last good opportunity to camp before entering the heart of the malpais. Ponderosa and juniper produce duff here, although the ground bristles with scoria. Setting a tent peg is difficult. The trail loops around the south end of Encerrito. On the east side the CDT reaches a signed junction with the Zuni-Acoma Trail. Go east (right if going north) and follow the combined trails into the heart of the malpais.

This is extraordinary terrain. Much of it is naked lava, forming steep hillsides and narrow gullies. Vegetation will not be denied, however, and every crack in the rock is an invitation for claret cup cactus, grama grass, juniper and mullein to colonize. Some of these cracks, moreover, are less like “crazes” in a sidewalk and more like crevasses in a glacier. Stresses in the cooling rock apparently introduced yard-wide gaps, gaps that cleave downward more than 25 feet. Fortunately, trail builders have been at work here for more than a 1000 years. Bridges were constructed by dropping rocks into the crevasses to chock across the gap, then pouring more rocks on top of the chock stones. These bridges makes crevass-crossing much easier, but looking down is still vertigo-inducing. And, again, navigation is not trivial. It takes time, but try to find that next cairn before leaving the previous cairn. Eventually the lava ends. It is just another two miles until, having traveled 54.8 miles, you arrive at the Zuni-Acoma trailhead.
Recommendations:
I did this in two and a half days, which was silly. A four day schedule would be better and there is currently enough water to support such a trip. Give yourself time to explore some of the cinder cones and investigate (cautiously) some lava caves.
This has been a markedly cool and wet year. Warm gear was a huge asset at 8000 feet. Good water-filtering gear, including filter-flushing gear, is essential.
The CDT Water Report presents a table listing water reports filed by CDT hikers. This one table covers the entire CDT. As a consequence it is huge and awkward to navigate. The easiest way to get started is to use the “Search By Mile Number” option at the top of the page. If you search for mile number “471.9” (without the quotes) then you should get an entry named “Junction To Water Tank”. This is the first water report on the Chain of Craters segment. It displays the single, most-current report for the tire tank. You can click on the “read more” button to see if there have been other reports for this resource. Browse down the table to check out the remaining water resources – the last relevant report is for the El Malpais Information Center.
Other than the faucet at the El Malpais Information Center, all water resources are provided by ranchers. It would not be possible to hike this stretch without their profound courtesy. Please return the favor by quickly collecting water and moving away from each water source. Your presence can stress the cattle (and wild life) badly.
This is not a good place to test out shoeless hiking! The sharp-edged lava is merciless – even the soles of trail shoes will take a beating. Consider wearing boots since the opportunity to twist an ankle is exceptionally high.

A succinct and well-written discussion of the Chain of Craters portion of this hike can be found at the Four Corners Tourism site, here. (Note that the southern-most portion of the trail no longer stays on County Road 42, but instead departs immediately from the Co Rd 42 at the kiosk).
Rambling Hemlock, an experienced backpacker, has a report on hiking the Chain of Craters as a two day venture in 2015. Some of the water resources were dry, and the hikers got by on the strength of tiny snow patches.
New Mexico Nomad has compiled an extensive report on the outdoor resources near the El Malpais National Monument, including the Narrows Rim Trail. If you are visiting and want to see it all, then this is a valuable resource.
