The Altitude of Longs Peak 

Summit of Longs Peak

Longs Peak, standing at an impressive 14,259 feet, is one of Colorado’s iconic “fourteeners” and a true challenge for hikers and climbers alike. Longs Peak towers above the landscape, making it highly visible and historically significant in Rocky Mountain National Park. Its elevation places it among the highest peaks in the state, towering above most of Colorado’s already high-altitude terrain. While Colorado is home to 58 peaks exceeding 14,000 feet, Longs Peak is renowned for its prominence and technical difficulty, making it a bucket-list destination for adventurers.

For those ready to take on the challenge, Longs Peak’s lofty altitude reminds everyone that it’s a force of nature requiring careful planning and acclimatization.

Altitude Sickness at Longs Peak & Symptoms 

Are you curious about your chances of getting altitude sickness at Longs Peak? The risk is significant—at these elevations, even in the Rocky Mountains, 40% to 50% of individuals may experience symptoms.

At the altitude of Longs Peak, the air contains significantly less oxygen than at sea level—about 40% less. This reduction can have serious physical effects on the body, especially for those who are unacclimated. 

Longs Peak is categorized as a "very high altitude" environment, meaning it poses a higher risk for altitude sickness. Symptoms of altitude sickness can include headaches, nausea, and fatigue. In severe cases, unprepared climbers can face life-threatening conditions like HAPE or HACE, though these are rare.

  • AMS (Acute Mountain Sickness) - This is the most common form of altitude sickness, and while it's usually mild, it can progress to more severe conditions. Risk altitude: Typically occurs at altitudes above 6,000 feet (1829 meters). Symptoms: Headaches, nausea, dizziness, fatigue, sleeping issues, shortness of breath, and loss of appetite.
  • HAPE (High-Altitude Pulmonary Edema) - This is a severe condition in which fluid builds up in the lungs, making breathing difficult. HAPE is life-threatening and requires immediate descent. Risk altitude: Common at altitudes above 10,000 feet (3,000 meters). Symptoms: Extreme shortness of breath, persistent cough (producing frothy sputum), chest tightness, and extreme fatigue.
  • HACE (High-Altitude Cerebral Edema) - The most dangerous form of altitude sickness, HACE occurs when fluid collects in the brain. It requires emergency treatment.  Risk altitude: Generally occurs at altitudes above 12,000 feet (3,600 meters). Symptoms: Severe headache, confusion, loss of balance, hallucinations, and loss of consciousness.

7 Ways to Combat Longs Peak Altitude Sickness 

Getting ready the right way is the best way to combat altitude sickness and enjoy your hike. Preparation is essential, especially when tackling something as challenging as Longs Peak. Follow these simple tips to make the most of your adventure:

1. Take it Slow and Enjoy the Journey

Conquering Longs Peak is no sprint—it’s a marathon. The changing altitude can be tough, so pacing yourself is key. Going slow not only helps your body adjust and catch your breath but also keeps you safe by reducing the risk of falls or injuries on the uneven terrain.

Take regular breaks along the trail to let your body acclimate and soak in the breathtaking views. The Chasm Lake Trail Junction is a notable landmark where hikers can pause to enjoy scenic views and take a snack break. Plan rest stops at key points like the Boulder Field or the Keyhole to stay safe while enjoying the unique beauty of the route. Remember, it’s about the journey, not just the summit!

2. Hydration is Everything

At Longs Peak’s high elevation, your body can lose water faster due to drier air and increased breathing noted by Wildness Medical Society. Staying hydrated is critical to keep your energy up and may help avoid altitude issues.

Start hydrating the day before your hike and bring plenty of water or a hydration pack for the trail. Sip frequently, even if you’re not thirsty.

Quick tip: Want an extra boost? Add an electrolyte mix to your water or take chewable tablets for improved hydration and energy levels.

3. Adjust to the Altitude

Longs Peak’s altitude can hit hard if you're coming from lower elevations. Spend a day or two acclimating in nearby areas like Estes Park (7,522 feet) or even at Longs Peak Campground (9,500 feet).

This extra time allows your body to adjust to the thinner air and reduces the risk of altitude sickness. Trust us, a little patience before the hike will make a big difference when you’re climbing above 14,000 feet.

4. Skip the Alcohol

As tempting as that local craft beer might be, save it for after your climb. Alcohol dehydrates you and can worsen altitude sickness symptoms like headaches or nausea.

Instead, focus on your hydration and giving your body time to adjust to the elevation. That celebratory drink will taste even better once you’re safely back in Estes Park!

5. Fuel Your Body Wisely

Longs Peak is no ordinary climb—it’s a high-altitude full body workout. Make sure you’re fueling your body with the right nutrients.

Eat a hearty breakfast with carbs and protein before hitting the trail, and pack snacks like protein bars, or even some fresh fruit to keep your energy steady.

The high-altitude environment also induces oxidative stress, a condition in which harmful free radicals outnumber the antioxidants in the body. This can even impair physical performance and recovery. For an extra advantage, consider adding an antioxidant-rich supplement to boost and support your body.

6. Prioritize Quality Sleep

A good night’s sleep is your secret weapon for tackling Longs Peak. It helps your body cope with the altitude, boosts your energy, and sharpens your focus for the challenging terrain.

Bring warm gear if you’re camping nearby—temperatures can drop significantly at night. Keep your sleep schedule consistent and try to relax the evening before your hike to set yourself up for success. Also, a moderate dose of natural sunlight during the day can improve the quality of your sleep the night before you climb.

7. Know Your Limits

Climbing Longs Peak is a formidable challenge, so staying attuned to your body's limits and signals is essential. It might be time to turn back if you start experiencing symptoms like dizziness, nausea, or severe headaches. Altitude sickness can escalate quickly, and it’s better to play it safe than to push through. There’s no shame in calling it a day—Longs Peak will always be there for another attempt. Safety always comes first.

Follow these tips, and you’ll be ready to take on the iconic Longs Peak with confidence! With preparation, caution, and a sense of adventure, you’ll create lasting memories on one of Colorado’s most stunning mountains.
