    The Mount Bierstadt hike is a popular trail and a great introduction to hiking a Colorado 14er. If you are hiking in the early or late part of the season be sure to be ready for some snow and ice as you hike this spectacular Colorado peak!

    Route Description for Mount Bierstadt Hike

    The Mount Bierstadt hike might be the best introduction to a Colorado 14er. This popular mountain is an easy drive from Denver. Starting the hike at the Guanella Pass Trailhead, the most popular route up the mountain is via the West Slopes.

    Follow the Mount Bierstadt Trail along a flat marshy alpine meadow and across wooden bridges to the base of Mount Bierstadt, which is directly ahead of you. The start of the trail descends from the Guanella Pass trailhead toward Scott Gomer Creek, weaving through willow trees on wooden bridges and well-marked trails. An impressive view of the Sawtooth Ridge will be visible to the left of Mount Bierstadt. Cross the creek and pass away from the willow trees, beginning the ascent of Mount Bierstadt itself. As the trail climbs in elevation, the trail switches back across the west slope of the mountain.

    Pass over the rocky shoulder, and you’ll see the summit rising up ahead of you. Eventually, the trail will become steeper and rockier as you approach the summit. This part of the trail is prone to very strong winds, so take care and make sure to come well prepared with plenty of layers. Follow the cairns across the large boulders through the Class II section of the hike. The summit of Mt. Bierstadt (4,285 m) will level off with a panoramic view of the Colorado Front Range and Mount Evans to the east. If you have the energy, you can extend the hike by continuing to Mount Evans itself.

    To return, hike back the way you came.

    Hiking Trail Highlights

    Mount Bierstadt

    Mount Bierstadt is a high mountain peak in the Colorado Peaks of the Rocky Mountains, near Denver. This mountain is not only a popular hiking destination, it’s also a wonderful place for climbers. This is because even though it's 4,285 m tall, it's considered to be one of the easier climbs for a mountain over 4,267 m, also called one of the 14ers.

    Mount Bierstadt was named after the famous American landscape painter, Albert Bierstadt, who reportedly made the first recorded summit of the mountain in 1863. Some of his best-known work was inspired by his trip to the region, including the painting A Storm in the Rocky Mountains, Mt. Rosalie. This spectacular landscape has been inspiring artists and writers ever since.
