UPS is the upper most singletrack on the Porcupine Rim. It connects the Kokopelli Trail with LPS
UPS starts at a juntion with the Kokopelli route on the right shortly after a cattle guard; it's well signed.
UPS is the kind of trail where things get really good, really fast. After the short climb to the rim from the trail junction, you'll be overlooking Castle Valley. From here, the trail begins connecting short bits of wavy slickrock. The frequency of rock depends on how close you get to the rim. The closer you are, the more slickrock there is to enjoy.
After going along for a bit, you'll get to large slickrock. The trail is to the right, but there are multiple ways to get down.
The steep slick rock area will lead to Malloy Park and the Porcupine Rim Camping Area. The trail braids here a bit, but keep heading north along the rim and you'll get back on track. Afterwards, a little more smooth trail and slickrock will connect you with LPS
