Mt Bierstadt Route Description
A word on parking – the Mt Bierstadt route is extremely busy, especially on weekends and summer months. Those hiking Mount Birstadt should aim to arrive before dawn if they want a parking spot at the pass. If the upper trailhead is full, you may need to park at a lower pull-off, adding miles and frustration to your start.
The start of the Mt Bierstadt route leaves the Guanella Trailhead along the well-groomed trail. Looking ahead, if there is enough light, you will be able to see the Sawtooth straight ahead and above of you. You’re hiking Mount Bierstadt, which is the tall peak to the right of this jagged ridge.
You’ll lose several hundred feet of elevation as you approach Scott Gomer Creek. There are great boardwalks to keep you out of mud, and you pass by good areas to see elk and moose by the lake. At the Creek crossing, use the rocks to cross and take your time… Take care as you cross to avoid getting wet shoes – no fun at all!
After the creek crossing, the Mt Bierstadt route gradually picks up elevation as you head towards a small rib – this is your route up to the broad, gentle west slope. The trail here gets more rocky and the elevation gain picks up considerably. Take breaks as necessary to catch your breath and take a drink of water, and admire the view as you climb higher.
Once up on the West Slopes, you begin to take a series of gentle switchbacks up the mountain. Be mindful of the trail – cutting the path leads to long-term damage. Look for the series of large poles installed by the Colorado Fourteeners Initiative along with the large cairns (rock piles) to stay on track. This is a good spot to stop for a break and check the weather before continuing hiking Mount Bierstadt.
This next part of the Mt Bierstadt route can feel monotonous and exhausting as the altitude really begins to sap your strength, but the summit is worth it!
Continue following the trail and cairns, switchbacking slightly and heading across the slopes. Reach the saddle below Mt. Bierstadt, and admire the view down into the gorge below from a distance. In early summer and spring, stay away from the snow cornice that forms along this ridge, as it can fail and take you with it.
After you reach this summit ridge, take a left straight up the hump of boulders lying in front of you. From here, you aren’t hiking Mount Bierstadt, so much as you’re climbing it. There are many different ways to scramble up this final section. You can look for cairns to mark trail segments that are easy, or create or own line for more of a challenge. There may be snow if you are climbing early in the year – avoid it if you can unless you have the right gear to handle it.

Leave No Trace at Mt Bierstadt
When setting out to hike Mount Bierstadt, integrating Leave No Trace (LNT) principles is crucial for preserving the delicate alpine environment of this Colorado 14er.
The following section offers guidance on how to minimize your impact while enjoying the great outdoors:
Plan Ahead and Prepare
- Understand the regulations and special concerns for the area you’ll visit.
- Check the weather forecast, and be aware of the terrain challenges you might face on Mt Bierstadt.
- Preparation reduces the likelihood of resource damage and contributes to your safety.
Travel and Camp on Durable Surfaces
- Stay on established trails and avoid cutting switchbacks, which can lead to erosion.
- In the alpine tundra, plants take years to grow and mere seconds to be destroyed by trampling.
- If camping is part of your trip, use designated campsites at lower elevations to minimize impact.
Dispose of Waste Properly
- Pack out all your trash, leftover food, and litter.
- It’s essential to carry a bag for collecting waste.
- For human waste, dig a cat hole 6-8 inches deep at least 200 feet from water, trails, and camp. Cover and disguise it when finished.
- Pack out all toilet paper and hygiene products.
Leave What You Find
- Preserve the past; examine, but do not touch, cultural or historic structures and artifacts.
- Leave rocks, plants, and other natural objects as you find them.
- Avoid introducing or transporting non-native species by cleaning gear and boots before and after your hike.
Minimize Campfire Impacts
- Campfires can cause lasting impacts in the alpine environment.
- Use a lightweight stove for cooking and a lantern for light.
- If fires are permitted, use established fire rings, keep fires small, and burn all wood to ash.
- Put out fires completely and scatter cool ashes.
Respect Wildlife
- Observe wildlife from a distance and never feed them. Feeding wildlife damages their health, alters natural behaviors, and exposes them to predators and other dangers.
- Control pets on a leash at all times, or leave them at home.
Be Courteous to Others Outdoors
- Respect other trail users and protect the quality of their experience.
- Use headphones, not bluetooth speakers, and keep your noise down.
- Give uphill hikers the right of way.
- Step to the downhill side of the trail when encountering pack stock.
- If stopping, move off the trail to allow others to pass.
Incorporating these LNT principles into your Mt Bierstadt adventure is a commitment to conserving the mountain for future generations to experience and enjoy. By acting as stewards of the land, we can all contribute to the sustainability of the natural beauty that draws us to these heights.

Safety Tips for Hiking Mt Bierstadt
Mt Bierstadt, standing tall at over 14,000 feet, offers a majestic experience but also poses unique challenges. It is one of the most difficult class 2 peaks in the state, and people have been seriously injured or killed there in recent years. Prioritize your safety with these essential tips:
Acclimate to Altitude: Spend a day or two at a lower elevation near Mt Bierstadt to get your body used to the altitude. Altitude sickness can be a serious concern and can strike regardless of fitness level.
Check the Weather: Mountain weather is notoriously unpredictable. Before you set out, check the local weather forecast and be prepared for sudden changes. Start early to avoid afternoon thunderstorms common in the Rockies.
Stay Hydrated: At high altitudes, your body dehydrates faster. Carry plenty of water — a minimum of 2 to 3 liters per person — and drink regularly throughout your hike.
Research Your Route: Take time to review trip reports, route descriptions, maps, and photos to help you navigate in the field and know if you are on the right track.
Dress Appropriately: Layer your clothing to adapt to the variable conditions. Include a moisture-wicking base layer, an insulating layer, and a waterproof and windproof outer layer. Don’t forget a hat and gloves, even in summer.
Stay on the Trail: For your safety and the environment’s protection, stick to designated trails. Shortcuts can lead to erosion and habitat destruction and can also put you at risk of getting lost or injured.
Know Your Limits: Mt Bierstadt’s terrain can be challenging, with loose rocks and steep sections. If you’re not an experienced hiker or if you’re feeling unsure, consider hiring a guide or joining a group.
Emergency Plan: Have a plan in case of an emergency. Inform someone of your route and expected return time. Carry a whistle, a mirror, and a small first aid kit. A satellite messenger or personal locator beacon (PLB) is advised for remote areas where cell service is not reliable.
Bring a Buddy: Never hike alone. Use the buddy system to ensure safety. If one person gets injured or sick, the other can go for help.
- Share Your Itinerary: Tell someone dependable back home that you are climbing Mt Bierstadt and share as much of your plans and itinerary as possible. Tell them you when you will check-in with them, and who to call if you fail to do so.
Respecting these safety guidelines will help ensure that your climb up Mt Bierstadt is memorable for all the right reasons. Stay alert, stay safe, and enjoy the grandeur of the Rockies.

About Mount Bierstadt
Mount Bierstadt is named after Albert Bierstadt, a famous landscape painter after he climbed it in 1863, the first recorded ascent. However, it is likely native Americans have been ascending and hiking Mount Bierstadt for hundreds, if not thousands of years.
Mount Bierstadt is one of the busiest fourteeners in Colorado, with thousands hiking Mount Bierstadt every summer. This popularity, due to the peak’s proximity to Denver, accessible trailhead, and easy route, is increasing each year. The 14er is typically climbed in summer via the West Slopes, a class 2 route. It can also be climbed from Mount Evans via class 3 routes along its east ridge or the Sawtooth.
During winter months, the Guanella Pass area closes, adding around 1 mile to the climb up Mount Bierstadt. Even with this extra distance, hiking Mount Bierstadt remains one of the best winter 14er adventures for beginners. Be sure you plan ahead and bring the right gear if attempting a winter ascent. With nearly empty trails during winter months, this may be the best time of year for hiking Mount Bierstadt, if you’re prepared.
With use continuing to grow in the area, the Forest Service is considering new use restrictions or policies. Help manage the impact in the short term by hiking Mount Bierstadt on non-peak visit days, and by following Leave No Trace ethics when you visit.

Mt Bierstadt Frequently Asked Questions
Below are some of the most common questions we get asked about hiking Mt Bierstadt.
If you do not see your question addressed below in our FAQs, leave it in a comment at the bottom of the page and we will get an answer to you as soon as possible.
A: Everyone moves at a different pace based on their fitness, acclimation, gear, and experience. On average, people take around 5-7 hours round-trip to climb Mount Bierstadt and get back to the trailhead. If you are climbing in poor conditions or during the spring or fall, it will likely take a little longer.
A: The Mount Bierstadt 14er hike is relatively easy compared to other peaks in the state. However, it still requires you to hike for 7 miles and gain nearly 3,000 feet of elevation in a low-oxygen environment. Most people move much more slowly and get tired much faster than they do normally while hiking. Give yourself plenty of time to reach the summit and try not to overestimate your abilities if it is your first 14er.
A: During the summer the biggest issue is finding a parking spot at the extremely busy Guanella Pass trailhead. I recommend arriving before dawn on weekends – around 5am if possible – if you want to be certain you’ll get a spot. During the week, 6am is usually early enough for good parking. During the spring and fall when there are less visitors, you can stretch it to 7am if you need to.
A: You do not need any reservations or permits to hike Mt Bierstadt. However, the area is very busy and parking is limited. Plan to arrive pre-dawn if you are visiting during the summer on a weekend or you might not be able to find parking to hike Mt Bierstadt. Camping in the area is limited to designated campsites and campgrounds; no dispersed camping is allowed on Guanella Pass.
A: The parking lot at Guanella Pass is pretty barebones. There is a pit bathroom open from late spring through early fall, as well as a sign with information at the trailhead. Other than that, you are on your own.
A: First, get there early. Parking is very limited and fills quickly during the summer, especially on the weekend.
Second, be mindful of the route as you move through the Willlows as it can be easy to lose the trail.
Third, remember to pace yourself – this is not a race. It is better to move slower but more consistently than to move quickly with frequent breaks. Likewise, it is better to take fewer, longer breaks than to take many short breaks.
Lastly, remember to leave no trace while visiting Mount Bierstadt. Keep your dogs leashed and on the trail and clean up after them. Pack out trash, leave what you find, and be respectful to wildlife and other people sharing the trail.
