Planning an epic RV adventure in the Colorado Rockies? The stunning mountain vistas and crisp alpine air await, but there’s one challenge many RVers don’t anticipate: altitude sickness. Whether you’re heading to Rocky Mountain National Park or exploring the high country around Breckenridge, understanding how elevation affects your body can make or break your mountain camping experience.
What is Altitude Sickness and Why RV Campers Need to Know
Altitude sickness, medically known as acute mountain sickness (AMS), occurs when your body struggles to adapt to reduced oxygen levels at high elevations. In Colorado, this becomes a real concern once you climb above 8,000 feet – and many popular RV camping destinations sit well above this threshold.
Key Colorado RV destinations and their elevations:
- Rocky Mountain National Park: 7,500-12,183 feet
- Breckenridge: 9,600 feet
- Leadville: 10,152 feet
- Alma: 10,361 feet
Unlike traditional campers who might hike gradually to elevation, RV travelers often drive directly from sea level to high-altitude campgrounds in a matter of hours. This rapid ascent gives your body zero time to acclimatize, making altitude sickness more likely and potentially more severe.
The symptoms can range from mild headaches and fatigue to severe nausea, dizziness, and sleep disruption – none of which sound fun when you’re trying to enjoy your mountain getaway. For RV campers planning extended stays at elevation camping spots throughout Colorado, understanding prevention strategies becomes crucial.
Early Warning Signs Every RV Camper Should Recognize
Mild Altitude Sickness Symptoms:
- Persistent headache (often described as a “hangover” feeling)
- Unusual fatigue or weakness
- Nausea or loss of appetite
- Dizziness or lightheadedness
- Difficulty sleeping or restless nights
These symptoms typically appear 6-24 hours after arriving at altitude and can persist for several days if not properly managed.
More Serious Warning Signs:
- Severe, debilitating headaches
- Vomiting that prevents keeping fluids down
- Extreme fatigue where simple tasks become exhausting
- Confusion or difficulty thinking clearly
- Loss of coordination
If you experience severe symptoms, it’s time to consider descending to a lower elevation immediately. The good news? Most RV campers experience only mild symptoms that resolve within 2-3 days with proper care.
Pre-Trip Preparation: Setting Yourself Up for Success
Start Hydrating Days Before Your Trip
Begin increasing your water intake 3-4 days before departing for high-altitude camping. Dehydration compounds altitude sickness symptoms significantly. Aim for at least 3-4 liters of water daily, and avoid alcohol during this preparation period.
Consider Gradual Ascent When Possible
If your schedule allows, plan overnight stops at intermediate elevations. For example, when traveling from Denver (5,280 feet) to Rocky Mountain National Park, consider spending a night in Boulder (5,430 feet) or even Estes Park (7,522 feet) before heading to higher campgrounds.
Pack Smart Prevention Supplies
Stock your RV with:
- Extra water bottles and electrolyte supplements
- Ibuprofen or acetaminophen for headache relief
- Ginger supplements or tea for nausea
- A pulse oximeter to monitor oxygen saturation levels
- Comfortable pillows for elevated sleeping
Consult Your Doctor for Medication Options
Acetazolamide (Diamox) can be prescribed to help prevent altitude sickness. This medication helps your body acclimatize faster by increasing breathing rate and improving oxygen uptake. Discuss this option with your healthcare provider, especially if you have a history of altitude sensitivity or plan to camp above 9,000 feet.
Day-by-Day Acclimatization Strategy for RV Campers
Day 1: Arrival and Assessment
Your first day at altitude should be intentionally low-key. Set up your RV, get familiar with the campground, but avoid strenuous activities. Take note of how you’re feeling and establish a baseline. Light walks around the campground are fine, but save the serious hiking for later.
Monitor your symptoms hourly. Keep a simple log in your phone noting energy levels, headaches, and appetite. This helps you track whether you’re improving or if symptoms are worsening.
Days 2-3: Gradual Activity Increase
If you’re feeling stable, gradually increase activity levels. Start with short, easy hikes or longer walks. Pay attention to your breathing and take frequent breaks. Your body is working harder to extract oxygen from thinner air, so activities that feel easy at sea level will be more challenging.
Continue prioritizing hydration and rest. Many RVers make the mistake of trying to pack too much into their first few days at altitude.
Day 4 and Beyond: Normal Activity Levels
Most people fully acclimatize within 3-5 days. You should notice improved energy levels, better sleep, and the ability to engage in normal hiking or outdoor activities without excessive fatigue.
Remember that acclimatization can vary significantly between individuals. Some people feel great after 24 hours, while others need a full week to feel completely normal.
Essential Hydration and Nutrition Strategies
The Colorado RV Hydration Formula
At high altitude, your body loses fluids faster through increased breathing and higher urine production. The general rule: drink enough so your urine remains light yellow throughout the day.
Smart RV Hydration Tips:
- Keep water bottles throughout your RV for easy access
- Add electrolyte tablets to prevent overhydration
- Drink small amounts frequently rather than chugging large quantities
- Monitor intake with a water bottle that has measurement markings
High-Altitude Nutrition Guidelines
Your body burns more calories at elevation, so don’t be surprised if your appetite increases after the first day or two. Focus on:
- Complex carbohydrates: Pasta, rice, and whole grains provide sustained energy
- Iron-rich foods: Spinach, lean meats, and beans support oxygen transport
- Potassium sources: Bananas, potatoes, and avocados help with fluid balance
Limit alcohol consumption, especially during your first 48 hours at altitude. Alcohol can worsen dehydration and mask altitude sickness symptoms, making it harder to assess how you’re truly feeling.
Sleep Solutions for High-Altitude RV Camping
Sleep disruption is one of the most common complaints among high-altitude RV campers. The thinner air can cause periodic breathing patterns that wake you frequently throughout the night.
RV-Specific Sleep Optimization:
Elevate your head using extra pillows or by adjusting your RV’s leveling jacks to create a slight incline. This helps improve breathing during sleep and reduces morning headaches.
Temperature Management
Mountain nights can be surprisingly cold, even in summer. Your body works harder to stay warm at altitude, which can further disrupt sleep. Ensure your RV heating system is functioning properly and consider bringing extra blankets.
Creating the Ideal Sleep Environment
- Use blackout curtains to block early mountain sunrise
- Consider a white noise machine to mask campground sounds
- Keep the RV temperature slightly cooler than you might at sea level
- Avoid large meals 3 hours before bedtime
Some RVers find that a small fan helps circulate air and provides psychological comfort, even though it doesn’t actually increase oxygen levels.
When to Seek Medical Attention or Descend
While most altitude sickness cases resolve with time and proper care, certain symptoms require immediate action.
Immediate Descent Indicators:
- High-altitude cerebral edema (HACE) symptoms: severe confusion, lack of coordination, or altered mental state
- High-altitude pulmonary edema (HAPE) symptoms: shortness of breath at rest, wet cough, or chest tightness
- Inability to keep fluids down for more than 12 hours
- Symptoms that worsen after 24-48 hours instead of improving
Finding Medical Care in Colorado Mountain Communities
Most popular RV camping areas have medical facilities within reasonable driving distance:
- Estes Park Medical Center (near Rocky Mountain National Park)
- Summit Medical Center in Frisco (Breckenridge area)
- St. Joseph Hospital in Denver (for serious cases)
Keep emergency contact numbers programmed in your phone and know the route to the nearest medical facility from your campground location.
RV-Specific Altitude Considerations
Generator and Appliance Performance
Your RV’s equipment will also struggle with high altitude. Generators lose roughly 3% of their power output for every 1,000 feet of elevation gain. A generator rated for 3,000 watts at sea level might only produce 2,400 watts at 8,000 feet.
Propane System Adjustments
Propane appliances may require adjustment at high altitude for optimal performance. Your water heater, furnace, and stove might burn less efficiently, producing more carbon monoxide. Ensure your CO detector is working properly and consider having propane appliances serviced before high-altitude trips.
Water System Management
Water boils at a lower temperature at high altitude, which affects cooking times and may impact your RV’s hot water system efficiency. Additionally, plastic water containers can expand or contract with pressure changes, so monitor your fresh water tank for any issues.
