Hiking Colorado’s 14ers: Everything You Need To Know

By Ellie Stanton

Updated:

Colorado is home to 53 mountains with summits that reach over 14,000 feet. Colloquially referred to as fourteeners, these peaks promise great views, challenging adventures, and a whole lot of walking. Whether you want to bag all 53 or just see what the state has to offer, here is an ultimate guide to hiking Colorado’s fourteeners.

When to Hike 14ers in Colorado

The fourteener season depends on winter snowpack and conditions. Though all 14ers can have snow year-round, in general, most trails are dry by late June and early July. Shorter days, harsher weather and lower temperatures come around early October, marking an end to the summer 14er season. If you are looking for a chilly adventure, some 14ers like Quandary Peak and Mt. Sherman can make for exciting winter ascents. You can learn more about snow hiking here!

Timing your hike depends on several factors including the mileage and elevation of the trail, your personal fitness and acclimation level, and the technical difficulty (learn more about this under the section “The Rating System”). To avoid summer thunderstorms, the rule of thumb for Rocky Mountain fourteeners is to summit by midday and return to the valley by early afternoon. Many fourteeners require “alpine starts,” or waking up before the sun rises. If you are a certified anti-morning person, don’t stress too much; I promise the views are worth it!

How to Train

Hiking a Colorado fourteener is no simple task. A well-thought-out exercise regimen will prepare your body and increase your chances of summiting. Here are some recommendations on how to train for hiking a fourteener:

  1. Plan Ahead: No amount of running uphill will prepare you if you just started doing it the day before your hike! Depending on your fitness, experience, and acclimation, plan on starting your training around 3 months before your adventure.
  2. Cardio vs. Weight Lifting: Training for a fourteener, like many sports, requires a combination of cardio and strength training. Aerobic workouts, like running and biking, will improve your body’s ability at transferring oxygen to your tired muscles. Activities that build your aerobic index is critical before high altitude missions like hiking a fourteener. I recommend frequent, moderate intensity exercise at 70 to 80 percent of your maximum heart rate. To prepare your muscles for steep trails and lots of steps, incorporate around 3 days of strength training to your workout routine. Here are some exercise and fitness tips from Backpacker magazine to get in shape for hiking.
  3. Stay Loose: All this training can put a strain on your muscles. Stretching and rest days are crucial for muscle recovery and growth. Try throwing in some mindfulness and meditation in your training routine to strengthen your physical and mental health. Check out your local yoga studio for some classes! If you prefer to stay home, check out free classes on Youtube from channels like Yoga with Adriene.
  4. Know and Grow Your VO2 Max: Your VO2 max is your maximal oxygen uptake – the maximum amount of oxygen your body can use during intense exercise. VO2 max is a great indicator for your cardiovascular fitness level and/or aerobic endurance. You can measure your VO2 max with a fitness tracker or using an online VO2 calculator. Any kind of challenging, aerobic activity will increase your VO2 max. Try adding short bursts of intense intervals to your workout, where you reach around 85 percent of your maximum heartrate for ten to twenty minutes. No worries if you find yourself winded after these exercises! Remember that training is a process, respect your body and its limits, and drink lots of water! You can learn more about how to measure and improve your VO2 max here.
  5. Train up High: The summit of a fourteener is at or more than 2.5 miles high. So, not only are you hiking a ton but you are doing it with a lot less oxygen! To acclimate your body and prevent altitude sickness, bring your training regimen to the hills.
  6. Train with Weight: Some fourteeners are multi-day adventures. If you plan to carry a heavy pack, practice hiking with extra weight. I like to stuff my backpack with bottles and/or milk jugs filled with water, and take to my local trails.
  7. Lengthen Training Sessions: No matter your fitness level (even if you are Kyle Richardson), a fourteener will take you more than a few hours to summit. To prepare your body for a long day (or days!), extend the duration of your training sessions. Dedicating a weekend or day to a big hike is a great way to get started.

Safety Tips

Each year, there are a few casualties on Colorado’s fourteeners. Some of the deadliest summits, like Longs Peak, happen to be the most popular. Here are some safety tips when hiking a fourteener:

  • Pick a Partner: Though experienced hikers can safely summit a fourteener on their own, make sure to bring a partner if you are beginner. A hiking buddy can help if you get hurt or lost. When choosing a fourteener to hike, keep in mind that a group is only as fast as its slowest member. Make sure that everyone is comfortable with the length and technical difficulty.
  • Choose Wisely and Know Your Limit: Colorado’s fourteeners vary in difficulty, so make sure you understand the different classes before choosing a fourteener. Scroll down a little further to learn about the hiking rating system!
  • Understand Rocky Mountain terrain: This mountain range lives up to its name – erosion is slowly disintegrating every mountain, making rock fall a frequent occurance and couloirs a hazardous obstacle. Ask the locals about rockfall occurence, and keep safe by staying present and wearing a climbing helmet.
  • Pick the right time: Prevent getting caught in dangerous weather by choosing to hike on the right day and time of year. Websites like Mountain Forecast provide important temperature, storm, and wind speed information on all of Colorado’s fourteeners.
  • Have the courage to turn around: A popular saying in the Rocky Mountains is if you don’t like the weather, just wait 20 minutes. Know the signs of storm formation (e.g., dark clouds) and turn around if you have not reached the summit by noon. Lightning remains a significant hazard when hiking fourteeners, and it is always better to be safe than sorry.
  • Do not take shortcuts: Maybe a friend of a friend overheard an REI employee talk about a shortcut on a popular fourteener. Although they may save you some time, shortcuts contribute to erosion and increase the likelihood of getting lost. They are not worth it, so don’t be tempted.
  • Wear the right clothing: Choosing the proper clothing will keep you warm, dry, and safe from health complications like hypothermia. If you are on a budget or living a more sustainable lifestyle, check out REI’s used gear or Patagonia’s Worn Wear for cheaper, high quality outdoor clothing.
  • Bring the right gear: Double check your gear list and don’t be stingy! The right equipment can save your life in case of rockfall or an avalanche. Check out eBay or a military surplus store for more affordable deals.
  • Protect yourself from strong UV rays: Ultraviolet rays are stronger and more intense at higher elevations. Regardless of the cloud cover, everyone should wear sunscreen, long layers, and a hat. Keep your eyes protected with UV-protected sunglasses and/or goggles.
  • Know the signs of altitude sickness: Mild symptoms of altitude sickness can feel like a hangover – dizziness, nausea, and headaches. While these can be solved with rest and hydration, more severe symptoms like vomiting, confusion, and difficulty walking should be addressed immediately. Hydrate and return to lower elevation as safely as you can. If symptoms persist, seek medical attention.
  • Know what to do in case you encounter a wild animal: Click here for our wildlife safety tips.
  • Do not bother wildlife: Fourteeners are blessed with great wildlife. Just as a wild animal can threaten a hiker’s safety, a hiker can threaten a wild animal. Never feed or approach wildlife, doing so can desensitize them to humans and put them in danger. In Colorado, feeding big game animals like elk and mountain goats is illegal. Learn more about the Colorado Law here.
  • Enjoy the view and stay present: Taking pictures is a great way to preserve your memories and share them with friends, but may distract you from present hazards.

Leave No Trace

Leave No Trace created 7 principles to follow to minimize your impact when exploring the wilderness.

  1. Plan Ahead & Prepare to improve safety and prevent resource waste.
  2. Travel & Camp on Durable Surfaces to minimize erosion and ecosystem damage.
  3. Dispose of Waste Properly and take your trash with you!
  4. Leave What You Find (including that really pretty rock).
  5. Minimize Campfire Impacts and help prevent forest fires.
  6. Respect Wildlife and keep your distance.
  7. Be Considerate of Others and do not be a creep!

The Rating System

Fourteeners are assigned difficulty ratings based on the Yosemite Decimal System (YDS). The system organizes difficulty by “classes,” which range from 1 to 5.

Class 1: Easy hiking on a typically well-maintained trail that leads all the way to the summit.
Class 2: Most of Colorado’s fourteeners are class 2 and involve scrambling over rocks, boulders, and/or scree. These are normally of limited exposure where falls are likely not serious or deadly. However, they will take longer than a class 1 hike.
Class 3: There is a significant increase in risk between class 2 and class 3 fourteeners (e.g., steeper terrain and greater fall potential). Class 3 fourteeners require advanced scrambling, where you use your hands for most of the hike.
Class 4: These involve climbing where handholds and footholds are required for upward or downward progress. Falls can be fatal, so a rope is sometimes used on Class 4 routes. The terrain is often steep and dangerous.
