This is not the same as the Porcupine Ranch or Porcupine 4x4 Trails.

This is a fun little trail of ledges and rock, right on the edge of the canyon rim at the end. This is a very popular bike trail so watch out for them.

The Porcupine 4x4 Trail ends very near the start of the Porcupine Rim trail. You'll see it as a tight turn downhill near the start. To stay on Porcupine Rim, stay high and continue fairly straight at the intersection. Porcupine Rim follows the edge of Negro Bill Canyon as it heads east.

The trail starts near a pit toilet as a narrow climb on dirt mixed with slickrock spots. There are a few ledges right away, and many of them require careful tire placement. This is the start of many obstacles that lean you out toward the canyon.

You follow the trail up to and along the rim, always on rock slabs. There are a few ledges and some tight places to make your heart skip a beat. There are two obstacles that will require careful tire placement, and there is no room to turn around.

You'll see an optional right turn that heads uphill once you start to pull away from the main obstacles at the canyon's edge. You can take this for a short trip back up to Sand Flats Road, or use it later as a fast exit if you want to skip the obstacles on the way down.

Once you're away from the edge of Negro Bill Canyon, the obstacles aren't as precarious. The biggest ledge is fun but it has a bypass. Then there is one more ledge before you come to the edge of Porcupine Rim.

Don't drive too fast unless you can always see what's in front of you, because the trail basically ends at a cliff called High Anxiety. You can stand right on the edge of one of the highest cliffs Moab 4x4 trails let you get near. This is a great place to break for lunch and watch people on bicycles come through on their way along the Whole Enchilada trail.

You can keep going for a little while, riding along the edge of the cliff. Eventually it turns into a bike trail only and you have to turn around and go back out the way you came in.
