Trail Information


The valley below Pierson Mountain is known as Pierson Park. Pierson Park Road South travels through the backcountry south of Estes Park, Colorado. Along the trail, you will find several opportunities to view the iconic 14er, Longs Peak, which is only a few miles to the west. With an abundance of dispersed camping along the road, Pierson Park is a popular destination for those visiting the Rocky Mountain National Park and Estes Park, Colorado. In 2013, heavy rainfall created havoc on the landscape of the surrounding area. The excessive rain caused a significant landslide from the Twin Sisters Mountain that borders the western edge of Pierson Park Road. The landslide was deemed unstable by the US Forest Service and the Pierson Park Road was basically cut in half by the natural disaster. Today, the once-through road is open as an out-and-back from the north and from the south. Remnants of the landslide are still clearly visible on the eastern slope of Twin Sisters Mountain.

This was my first time running this trail. It seemed to be in good shape. On this Tuesday morning run I only saw 1 other Jeep and 1 SxS. You're in the trees most of the time but there are some great views from the clearings.

Another great trail. I linked this up with Johnny Park this afternoon. The trail is in good condition for the most part. UTVs are digging holes at waypoint 5, they look worse than they were to drive. Awesome scenery, I might need to go back and camp out there...

Went down this in a stock height escalade esv on 285/70s. The drop into the valley is slippery at waypoint 5 and not the best time for long wheelbase vehicles. It's a pretty tight turn at the top coming into it. Beautiful trail.

You’re in trees the whole time so not many views (except on the way back out, awesome views of Long’s Peak). Reminded me of Balanced Rock road off Rampart.
