Trail Information

Highlights

This route has many highlights. Make sure to bring the camera for great desert scape photos. The Boulder OHV area is free to use and offers camping, bathrooms, and an OHV practice arena for kids. Quickly you'll find an optional obstacle, a small-waterfall for some shenanigans that allows you to get some flex on. Just after the waterfall you will find an old windmill with a larger area to make a stop. This trail takes you through sandy washes and up to the tops of roller-coaster-like peaks with breathtaking views. This is a very narrow trail when climbing the high peaks that give a bit of the pucker factor with little to no room for turn arounds. You descend back down into the wash and end the loop where you began -- making it nice for vehicles that are towed to the trail head or if you are camping out.

Did this trail today. It’s lots of fun. The waterfall obstacle is fun to play on for sure. There’s one steep climb that is fun. There is one decline that is steep, bends to the driver’s side out of view, and has a large washed hole along the driver’s side. Take it slow and be prepared for the rear ended to slide a little. Not sure if it should be a 5. Waterfall is optional and there isn’t really anything after that which cannot be done in a stock Wrangler. Fun trail just out of Phoenix. I recommend it for a fun time.

Due to extremely high fire danger, exceptional drought conditions, resource availability, and increased fire activity, the Department of Forestry and Fire Management and the Arizona State Land Department will implement closures to State Trust Land throughout Arizona. These closures are also in conjunction with our USFS partners. As of 8am on June 25, 2021, closures will be implemented on state-owned and managed lands in all 15 counties. All state-owned and managed lands are closed to entry for recreational purposes, including hunting, camping, and off-road vehicle use. Target shooting and fireworks are prohibited year-round.

We completed this trail in two different visits. The first time, on a Saturday, we came in via Morgan City Wash and met up with the trail at Waypoint 16. We than ran the trail backwards. That greatly reduced the brush and increased the fun factor climbing out of the wash with the steep incline, loose dirt, curved trail, and the small ledge in one of the curves. The front camera got a good workout due to numerous peaks where otherwise you only saw the hood and the sky. The second day we came in through the staging area and followed the trail to Waypoint 9 where we left this trail to follow LP9 north to meet with the northern end of LP10. From there we followed LP10 to meet back up with this trail at Waypoint 13 and continued on for the rest of this trail ending up back at the staging area. I much preferred the northern routes that we took on both days ... more steep inclines/declines and great views of the surrounding mountains and Lake Pleasant. The southern route from Waypoint 16 through Waypoint 20 spent more time down in the washes ... although it was still a a fun trail. Both days were dry and sunny with temps around 70 degrees ... doesn't get much better than that.

Having never explored the Boulder HOV area, it was suprising to see the vast network of interconnected trails–unless you know where you're going, you could easily get lost on one of many side trails. We ran this loop in what I'm guessing is the reverse of what the majority do, and the climb out of the wash was especially… interesting. I wouldn't recommend running it that way if you have a fear of heights, a very steep climb, and a sheer drop-off all in one ascent. The TrailsOffroad description "narrow trail when climbing the high peaks that give a bit of the pucker factor with little to no room for turnarounds" was pretty spot on - We had to help a broken down Jeep coming in the other direction stuck in the trail, and it required a lot of manuevering to get them to a safe spot so vehicles could get by.
