Trail Description

NOTE: Trail has been closed off at Private Property

Note: This trail was made in my Jeep, but it can be a great hike. Especially since this trail is scheduled to be "Decommissioned" by the Coronado National Forest when they publish their new Motor Vehicle Use Map (MVUM), then it will be the only way to visit the area. Please see their website for further information. Did you know that the new MVUMs released by the Forest Service will be closing more than 50% of the forest roads in Arizona? I would also recommend you voice your opinion on these closures. After all the discarded backpacks along the trail, I believe most of the traffic this trail receives is from illegal immigrants, not the 4WD community, and closure will not significantly reduce the environmental impact to the area.

Peña Blanca Canyon is a wonderful area and if you time your trip just right, it will be as though you're traveling through portions of the Amazon rain forest.

We got lucky on the day we made this trip. The area received about 3/4 to 1 inch of rain early that morning, roughly two hours before we got there. The wash was flowing nicely along its entire length on our drive to the waterfalls. Streams from side canyons created mini-waterfalls, pools and watery playgrounds for us to explore. The road was laden with water crossings it seemed to be bursting with green foliage, insects, amphibians and other critters. All of this made this adventure one of the best I've had in recent years.

One our way out (at about 1:30 pm), almost all the water in the first half of the trail was gone. Given this, I would rate the adventure 5 stars, but I also understand that not everyone will be that lucky. My guess is that on a "normal" day this would probably rate 3.5 out of 5 stars.

95% of the trail is an easy hike along a 4WD road with little elevation gain. You may have to get your feet (or more) wet along this trail if you go after any significant rain accumulation.

General Information and History

Peña Blanca Canyon is a small canyon in the Pajarito Mountain foothills about 10 miles north of our border with Mexico and the city of Nogales. The canyon runs north-south and is broken up by Peña Blanca Lake.

Peña Blanca Lake takes up about 50 acres of Peña Blanca Canyon and was created in 1957 by the Arizona Game and Fish Department. It's a beautiful desert oasis surrounded by grassy, oak-dotted hills and bluffs of limestone. Peña Blanca Lake is a popular recreation and fishing spot and can be crowded on the weekends in the summer.

The lake was drained in 2009 due to chemical contamination and to remove non-native plants and wildlife, It has been refilled and a new boat ramp installed. The new ramp is 48 feet long and 22 feet wide. It can be used to launch motor-powered boats, but boaters are restricted to one electric motor or one gasoline motor of 10 horsepower or less.

The Trail

NOTE: Trail has been closed off at Private Property

Note: This trail was originally done as a 4WD adventure, but could be done as a hike too. The pictures and video are from my original 4WD trip.

You can park at Waypoint 001 or follow the dirt road to the end of the road and start the hike from about Waypoint 002A if you want to cut off about a mile (roundtrip) from the hike. If you start at Waypoint 001, take a left onto the dirt track leading down into the wash (red track).

This part of the canyon is wide open and easy going. The trail crisscrossed the water when we were there. Continue walking in the wash for about another 1/2 mile and you will see some large concrete ruins on your right. Not sure what this was. During our visit, there were about 20-30 vultures crowded in a few of the trees.

They didn't seem to care that we were there and looked very content just sitting in the trees. I was able to get within 10 feet of them before they would reluctantly fly off to the nearest tree. I wondered why they were behaving so strangely. It was almost like they were stoned. As we left, we found the cleanly picked remains of a cow nearby. Now I knew why the vultures were acting like that. They were fat and lazy from what must have been something like a Thanksgiving dinner.

After another 1/4 of a mile, you'll reach the National Forest boundary (Waypoint 002A) and see a road to the right (yellow track). Keep going straight down the wash. Walk about another 1/2 mile until you reach Waypoint 003. Bear right at either the first or second trail (both take you into the correct canyon). You can see the gasline road heading out of the canyon on your left.

It is at this point that the Forest Service will be closing the road in the future. The track on the right leads through Walker Canyon (FR 223), which looks like it will be kept open. I have not taken this road yet.

Keep on the red track for another third of a mile and you will come to a fence line and a gate (Waypoint 004). Go through the gate and continue up the canyon for another third of a mile until you reach Waypoint 005. There's a nice camping spot on a high area and a small canyon that can be explored on your right.

After you're done exploring, continue up the canyon. After a nice rain, you will see a small waterfall coming off the side of the canyon a few hundred feet from the camping spot.

Continue up the canyon for another 1.75 miles until you reach Waypoint 006. There are a few other small side canyons you can explore and some beautiful spots along the way. Enjoy!

There's a large area under a shady tree at Waypoint 006. You will also note some shallow caves across the creek. It's obvious that illegal immigrants use this spot fairly often for shelter and a rest. We saw lots of discarded backpacks, water bottles and other trash in the area. But, it's still a beautiful spot.

Continue down the remaining portion of the road (which is less than 1/4 of a mile). When we drove this there was a lot of water and it was really deep here. A few hundred feet up from Waypoint 006 was the deep water crossing where the water went up to the middle of my doors.

Walk the 0.15 miles to Waypoint 007. This is the end of the road and the hike from here on gets a little more challenging. To get to the waterfalls, you must hike the next 0.15 miles. It's probably almost twice that distance if you consider the amount of times you need to crisscross the creek.

The waterfall is awesome (Waypoint 008). We saw a great deal of wildlife along the way: bright red and orange dragonflies, HUGE and colorful spiders, butterflies, small fish in the ponds and squirrels. The water comes from Peña Blanca lake not very far from the waterfall. I don't know for sure, by my guess is the water here is perennial.

When you're done enjoying the waterfall, head back the way you came in. Wasn't that awesome?
