Mount Princeton Road to Tigger Peak

While listed for jogging, the Mount Princeton Road to Tigger Peak route is primarily a strenuous hike, especially beyond the initial road sections. The lower part of Mount Princeton Road (CR 322/322A) is a gradual dirt road that can be jogged. However, past the radio towers (around 10,800 feet), the terrain becomes a challenging "rocky mess" with steep inclines, loose rocks, scree, and talus fields, making it unsuitable for running.

The initial section along Mount Princeton Road is a well-groomed dirt road. However, once you diverge onto the proper Mount Princeton Trail, the terrain drastically changes. Expect a very rocky path with steep ascents, loose rocks, scree, and talus fields. Some sections may even require scrambling. Patchy snow can persist on the ridge well into July, adding to the challenge.

You can start at the Mount Princeton Road Trailhead. For those with a 4WD vehicle, it's possible to drive further up to the Mount Princeton Upper Parking Area, which significantly shortens the strenuous ascent. Be aware that the road to the upper parking areas can be primitive and rough, and is subject to seasonal closures from November to June.

The best time to tackle this trail is typically from late June or early July through September, after the snow has largely melted from the higher elevations. However, even in summer, patchy snow can persist on the ridge. Always check current weather and trail conditions before heading out, as high altitude weather can change rapidly.

Yes, dogs are generally allowed on this trail within the San Isabel National Forest. However, they must be kept on a leash to protect wildlife and ensure a safe experience for all trail users. Given the challenging and rocky terrain, ensure your dog is accustomed to strenuous hikes and consider paw protection.

No specific permits are typically required for day hiking or jogging the Mount Princeton Road to Tigger Peak trail within the San Isabel National Forest. There are also no entrance fees for accessing this area. However, always check the latest regulations from the US Forest Service or local authorities before your trip, as rules can change.

This trail offers spectacular panoramic views throughout. You'll see expansive vistas of the Upper Arkansas River Valley, unique geological features like the sheer chalk cliffs, and other prominent peaks in the Sawatch Range such as Mount Antero and Mount Yale. The views from the ridge leading to Tigger Peak and the summit of Mount Princeton are consistently described as breathtaking.

Yes, this route utilizes sections of several other trails. You'll find yourself on parts of the Colorado Trail Seg. 13 North Cottonwood Creek Road to Chalk Creek Trailhead, Collegiate East, Mount Princeton Road, Lucky Mine Road, and the Mount Princeton Trail. It also briefly touches upon the main Colorado Trail (Segment 13).

Tigger Peak, at 13,300 feet, is an unranked "13er" adjacent to Mount Princeton. It's often climbed in conjunction with Mount Princeton and is unofficially named due to Princeton University's mascot, the Tiger. It offers excellent views as part of the larger Mount Princeton ascent.

Mount Princeton reaches 14,197 feet, and Tigger Peak is at 13,300 feet. High altitude is a significant factor on this trail. Proper acclimatization is highly recommended to avoid altitude sickness. Drink plenty of water, consider spending a day or two at a lower elevation (like Buena Vista) before attempting the full ascent, and be prepared to turn back if you experience symptoms of altitude sickness.

For a more manageable experience, especially if you're not attempting the full Mount Princeton summit, consider driving a 4WD vehicle to the Mount Princeton Upper Parking Area. This significantly cuts down on the initial road walk and elevation gain, allowing you to focus on the more scenic and challenging alpine sections. However, be aware of the seasonal road closures and the rough conditions of the upper road.
