Mount Princeton rises to 14,200 feet in the Collegiate Peaks of Colorado's Sawatch Range, named in honor of Princeton University. Its most striking characteristic is vertical relief: the mountain surges nearly 7,000 feet above the Arkansas River valley in only six miles, making it one of the most abrupt ascents in the range. The first recorded summit came on July 17, 1877, when William Libbey of Princeton University reached the top, though local miners had likely preceded him. The nearby Mount Princeton Hot Springs make the area a popular destination for both climbers and those seeking a post-hike soak.
The standard East Slopes route is rated Class 2 and begins along a forest road that climbs the flanks of unranked "Tigger Peak," a 13,300-foot subpeak. At around 11,800 feet, the road gives way to a trail that traverses a rocky ridge marked by cairns before ascending steep talus to the summit. From the 2WD trailhead at 8,900 feet the round trip covers roughly 13 miles with 5,400 feet of gain; a rougher 4WD road shortens this to about 6.5 miles and 3,200 feet. In winter, the north face of Tigger is avalanche-prone, and parties should plan to go directly over the subpeak rather than traverse beneath it.
The broad summit offers wide views across the Collegiate Peaks, the upper Arkansas valley, and the Mosquito Range to the east. Afternoon thunderstorms build quickly in summer, so an early start is essential.
