This elongated vessel of a rock has an interesting shape, but isn't as photogenic as others in the area: nestled in the canyon and colored in beige tones, it doesn't catch the sunlight in the same way. Getting to Submarine Rock, though, is more interesting than seeing it. You can drive up FR 179F, a very technical jeep trail that should be attempted only by highly skilled off-road-vehicle drivers, or you can take a jeep tour offered in town.
For experienced mountain bikers, Broken Arrow Trail, used heavily by cyclists and hikers, rolls across washes, red clay, and large mounds of slickrock. The 2-mile path is moderate but best done in the early morning in summer. Note that Submarine Rock is not the best retreat for serenity seekers: the rock abuts a popular jeep trail, which is clogged with tour jeeps revving over the rugged terrain.
