Route Description

Start at the Mount Princeton Trailhead, located at 8,900 feet elevation. The trailhead is accessible via County Road 162, about 4 miles west of Nathrop. A high-clearance vehicle is recommended to reach the higher parking area at 11,000 feet, but if you have a lower clearance vehicle, you can park lower and hike the additional distance.

From the trailhead, follow the rough 4WD road up to the radio towers at around 10,800 feet. This section is steep and rocky, but it’s well-defined. If you parked lower, it’s about a 3-mile hike to this point.

Continue past the radio towers along the 4WD road. After a short distance, you’ll encounter a trail junction. Take the right fork, leading towards the summit.

As you climb, the trail will become less distinct, transitioning into a boulder field. Use cairns (rock piles) to guide your way. The route through the boulder field requires careful footwork; take your time to navigate the loose rocks safely.

Continue ascending until you reach the saddle between Mount Princeton and Tigger Peak at approximately 13,000 feet. From here, the summit push begins. The trail becomes steeper and more rugged.

Follow the well-marked trail along the ridge. The final section involves some light scrambling over large boulders. Ensure you maintain three points of contact and check your footing.

At the summit (14,197 feet), enjoy breathtaking views of the Collegiate Peaks and the Arkansas River Valley. On a clear day, you can see for miles, taking in the vast beauty of the Rocky Mountains. Be sure you descend early enough to avoid afternoon thunderstorms and lightning.

Trailhead

There are two trailheads for Mount Princeton, including a lower 2WD-accessible trailhead and a 4WD-accessible trailhead further up along the access road.

There are no restrooms, drinking water, or trash service available at either trailhead. Come prepared with water and be ready to pack out your waste.

Lower 2WD Trailhead

The lower trailhead is accessible by all vehicles, high or low clearance alike. There is a large parking area with room for RVs, trailers, and other large vehicles.

The lower trailhead is open all year-round.

Upper 4WD Trailhead

The upper trailhead is accessible only by 4WD, high-clearance vehicles. This is a much smaller parking area, with room for 10-12 vehicles (at most). Get here early to secure a spot.

The upper trailhead closes each fall after the first major snowfall and reopens in June when the snow melts completely from the access road.

Directions

From Buena Vista: From the center of town, drive west on the County Road (CR) 306 for 0.7 miles. Turn left on CR 321 and continue south for 7.2 miles. Turn right onto CR 322 at a large sign. On CR 322, drive 0.8 miles to a fork in the road. Bear right into the Mt. Princeton trailhead. This trailhead is at 8,900′ and there is a large parking area.

If you have a good clearance 4WD, you can continue up the narrow 322 (Mt. Princeton) road. Just after the lower parking area, there is a fork in the road – stay right on the main road. Drive 3 miles to the radio towers at 10,800′. There is parking here for a couple of vehicles or turn left and continue on the 322A road.

About Mount Princeton

Mount Princeton, one of Colorado’s iconic 14ers, stands at 14,197 feet (4,327 meters) and is part of the Collegiate Peaks in the Sawatch Range of the Rocky Mountains. The mountain was named by Henry Gannett of the Hayden Geological Survey in 1873 after Princeton University, reflecting a common tradition of naming peaks in this range after prestigious universities.

The area around Mount Princeton has a rich history, initially inhabited by the Ute tribes who utilized the land for hunting and gathering. With the arrival of European settlers in the mid-19th century, the region saw an influx of miners during the Colorado Gold Rush. The town of Buena Vista, at the base of Mount Princeton, was established in 1879 and served as a hub for mining activities. The hot springs near the mountain were a significant draw for settlers and continue to be a popular destination.

Geology

Mount Princeton is part of the Sawatch Range, which was formed around 70 million years ago during the Laramide Orogeny, a period of mountain building that affected much of western North America. The geology of Mount Princeton is primarily composed of Precambrian granite, which is over a billion years old, and younger Tertiary volcanic rocks.

The mountain’s rugged terrain and prominent peaks were shaped by glacial activity during the Pleistocene epoch, which ended about 12,000 years ago. Glaciers carved out deep valleys and left behind moraines and other glacial deposits. One of the notable geological features of Mount Princeton is the Chalk Cliffs, located on the lower eastern slopes of the mountain. These cliffs are composed of highly eroded volcanic ash and tuff, creating a striking white appearance that contrasts with the surrounding landscape.

Mount Princeton also hosts several hot springs, which are a result of geothermal activity. These hot springs have been popular for centuries, initially with Native American tribes and later with European settlers and modern visitors seeking their therapeutic benefits.

Ecology

Mount Princeton’s ecology is typical of the high-altitude environments of the Colorado Rockies. The lower elevations of the mountain are characterized by montane forests, primarily consisting of Ponderosa pine, Douglas fir, and aspen trees. As you ascend, these forests give way to subalpine and alpine ecosystems.

The subalpine zone, found between approximately 9,000 and 11,000 feet, is dominated by Engelmann spruce and subalpine fir. Above the tree line, which is around 11,500 feet, the alpine tundra takes over. This zone is characterized by hardy grasses, mosses, and wildflowers that can survive the harsh conditions of high altitudes. Common wildlife in the area includes mule deer, elk, mountain goats, marmots, and various bird species such as the Clark’s nutcracker and the American pipit.
