Steep climb out of willows onto west slopes. Trail becomes rockier with loose scree sections. Switchbacks up to the ridge. Great views of Mount Evans begin. This is where you make up the elevation you lost and then some.

What's Special About Mt. Bierstadt?
Closest to Denver
Only 60 miles from Denver with fully paved highway access. You can leave Denver at 4:00 AM and be on the trail by 5:30 AM.
Introduction to Class 2
The Class 2 boulder field is well-cairned and provides excellent practice for hand use and route finding without serious exposure.
Clear Route
The trail is heavily trafficked and easy to follow. Cairns mark the boulder field clearly. It is very difficult to get lost.
Moderate Elevation Gain
At 2,850 feet of gain, this is less than many other 14ers. The initial descent through willows means less net climbing.

When to Go
Best Time of Year
July through early September
These months offer the safest conditions for beginners with minimal snow coverage and the most predictable weather patterns. Mid-July to mid-August is peak season with the best trail conditions.
Caution: Attempting this peak in June or late September significantly increases difficulty due to snow conditions. Winter attempts require mountaineering skills.
Time of Day
Early start for parking and to be off summit before noon thunderstorm window. Summer weekends fill parking by 6:00 AM.
Sunrise Bonus: Starting at first light gives you beautiful alpenglow on Mount Evans and Bierstadt as you hike through the willows.
Weather Considerations
Colorado mountain weather is unpredictable. The boulder field and summit are extremely exposed with zero shelter. Afternoon thunderstorms with lightning are the biggest danger. Be off the summit by noon. Take this seriously. If storms threaten, turn around immediately.
Pro Tips
Trekking Poles Essential
Trekking poles are highly recommended for the descent through the boulder field and for stream crossings in the willows. Your knees will thank you.
Watch the Willows
The willow section can be very muddy and boggy, especially early season. Waterproof boots help. Stay on boardwalks where provided to protect the fragile wetland ecosystem.
Sawtooth Ridge Connection
Advanced hikers can continue from Bierstadt to Mount Evans via Sawtooth Ridge, but this is a serious Class 3 scramble with significant exposure. Only for experienced climbers.
