The ridge walk to Tigger Peak also involves rocky sections, offering a challenging but rewarding experience.

This loop is considered a strenuous, Class 2 hike. Its difficulty largely depends on your starting point; beginning from a lower 2WD trailhead makes it a very long and challenging day with significant elevation gain. Starting from the Mount Princeton Upper Parking Area (accessible by 4WD) can reduce the mileage and elevation gain considerably, making it more manageable but still demanding.

This loop offers incredible panoramic views throughout. You'll see the valley below, the prominent Chalk Cliffs, and neighboring peaks like Mount Antero, Cronin, Grizzly, and Boulder. From the summit of Mount Princeton, the entire Sawatch Range is visible. The ridge walk to Tigger Peak also provides continuous scenic vistas.

Given the trail's difficulty and exposure, bring plenty of water, high-energy snacks, sun protection (hat, sunscreen), layers of clothing for changing weather, rain gear, and sturdy hiking boots. A map, compass or GPS device, and a first-aid kit are also highly recommended. Trekking poles can be very helpful on the rocky and loose sections.
