Hiking Mount Blue Sky | 14er Route Description, Map & Advice

Mt. Blue Sky is one of two 14ers with roads to their summit. However, that also means it’s relatively easy to climb by foot. It’s named after the man who ordered the Sand Creek Massacre that killed hundreds of Native American men, women, and children. Despite the dark history, climbing the peak is a refreshing treat, with many options for advanced routes due to the accessibility of the high country. Taking the road almost to the top and stopping at Summit Lake leaves you in the right place to climb the West Ridge. 

Here’s what you need to know to safely and successfully reach the summit.

Mt Blue Sky Route Description

The Mt Blue Sky route begins only 2,000 feet below the summit. Leave your car at the Summit Lake trailhead, and head north along the shore until you meet a sign marking a trail up Mt. Spalding. To begin hiking Mount Blue Sky, follow a loose trail up through the rocks to the ridge – don’t take the lower trail along the lake to your left.

Head up to the top of the ridge proper to get to a better trail. Climb until you reach the summit of Mt. Spalding (a good launch spot). The large basin you’re leaving was carved thousands of years ago by glaciers formed at the cliff walls above you.

From Mt. Spalding, you must head south to the saddle below the west ridge and Mt. Spalding. Follow a trail marked with cairns, but don’t worry if you leave the trail at times. Aim for the base of the ridge, just beyond this side (which has cliffs).

Work your way along the Western Ridge, following the cairns to find the path of least resistance. This can be a long, slow section of hiking Mount Blue Sky, with a bit of elevation gain and loss as you scramble up and down. Take your time and move carefully here. A fall is unlikely but wouldn’t be good for you.

With a bit of grit, you will soon come across the parking lot full of confused tourists wondering why you bothered hiking up a mountain with a road. Join the short trail from the summit parking lot to reach the summit before heading back for your descent. 

For an easier day out, come with two vehicles and leave one parked at the top for an easy drive back down. Enjoy your time, and make sure you head back to the tree line before the afternoon to avoid summer thunderstorms.

Leave No Trace at Mt Blue Sky

When setting out to hike Mount Blue Sky, 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 Blue Sky.
  • 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 Blue Sky 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 Blue Sky

Mt Blue Sky, 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 Blue Sky 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 Blue Sky’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 Blue Sky 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 Blue Sky is memorable for all the right reasons. Stay alert, stay safe, and enjoy the grandeur of the Rockies.

About Mount Blue Sky

Mount Blue Sky is the closest fourteener to Denver and the front range metro area, visible rising over the city skyline miles away. The mountain was originally named after John Evans, the controversial former Territorial Governor partially responsible for the Sand Creek Massacre. It was renamed Mount Blue Sky on September 15, 2023, which was a name suggested by the Arapahoe Tribe – it is a translation of their tribal name.

The road to the peak of Mount Blue Sky was built over a period of years from 1915 through 1930. It was originally part of a scheme by the city of Denver to develop Mount Blue Sky as a National Park. While the mountain was never granted this status, a road was still built to the summit, now the highest paved road in North America. The summit includes the remains of an old gift shop and restaurant which burned down in 1979. The foundation today is a viewing platform for visitors and those hiking to the summit.

Mount Blue Sky has been a significant place of research over the past 90 years due to its high altitude and road accessibility. Experiments into cosmic rays were carried out there in the 1930s, and the University of Denver maintains a telescope on the summit today for astrological research. It is also the scene for physics research, including a study that verified time dilation, a theory of Albert Einstein.
