How to Run Mt. Bierstadt

From the parking lot, take the trail toward the summit. The trail is well defined nearly the whole way. You’ll be paralell with the lake about 0.3 miles in. At 0.7mi, there is a shallow river crossing with plenty of large rocks to hop across [7]. From here, you’ll be in the willows. They are taller than most people’s line of sight, but the trail is wide and gentle [8]. At mile 1.8, 12,200ft, you’ll be on the saddle of the mountain. The terrain from here is extremely fragile alpine grass. Leave no trace by resisting stepping on any grass surface [12]. Large cairns and poles will mark the way. Near mile 3 at 13,200ft, the trail becomes thin and dissipates into rock. Follow cairns across generally stable, large rocks to the summit. Some big steps may be required, and use of hands for balance, though, vertical falling risk is minimal if you stay on route [16, 17]. The summit is rocky and offers views of a lake, and Mt. Evans and the Sawtooth [18]. The Sawtooth is technical class 3 travel, with vertical exposure and falling risks and is not for beginners. Weather can be extremely variable on this mountain, even in summer months. Go prepared.
