The Pinnacles Trail is one of the most popular trails in the Hog Canyon trail system. It is named after the interesting Pinnacles rock formation, also called the Beehives, encountered about a third of the way into the trail with an established picnic area next to it.
While this trail is known as the 'softer' route through the Hog Canyon area compared to the extreme route through Tom's Canyon, it is still a difficult trail requiring a modified 4WD vehicle, preferably with lockers. This trail is highly scenic and fun to drive, with much of it feeling like a sand and slickrock roller coaster as you cross numerous washes and gullies following the hillside above South Fork Hog Canyon. Steep sandy hills, slickrock ramps, rocks, and ledges abound. The most challenging obstacle is a series of sand-covered ledges on the final climb out of the canyon just before the end, for which lockers are very helpful.
From the end of the trail, you can either turn right on the Mosdell Trail and descend the difficult Mosdell Hill to loop back to the Hog Canyon Staging area or turn left and take the easier route out to the Crocodile Staging Area in Johnson Canyon. There are no established campsites along this trail.
