The trail begins out the main gate on Camp Casey. You cross the bridge and make a left along a narrow road. A little further up, you'll make another left and start the Machesan Trail.
The loop begins with a tough climb up a paved Machesan Fire Road. This road will eventually turn into a dirt Jeep trail. You'll then continue up to a ridgeline on Machesan Trail that flows up and down for a couple of miles. From there, you can either turn around at any nice viewpoint and ride the trail back or continue along Machesan Trail and down another road.
