Trekking Tips for Kilimanjaro & Meru

Essential information for high-altitude trekking and altitude sickness prevention

Important Notice

Climbing Mount Kilimanjaro or Mount Meru is an exhilarating adventure offering breathtaking views and a sense of achievement. However, high-altitude trekking carries inherent risks. The following information is intended to help you plan and prepare, but it is not a substitute for professional medical advice or high-altitude training. Always communicate any health concerns or symptoms of altitude sickness with your guide and group.

Understanding Altitude

Altitude affects everyone differently; susceptibility is not determined by age, sex, or fitness level

What is Altitude Sickness?

Altitude sickness (Acute Mountain Sickness, AMS) occurs when your body cannot adjust to lower oxygen levels at high altitudes. Understanding how your body responds to altitude is crucial for a safe trek.

How Your Body Adapts:

  • At sea level, oxygen concentration is ~21%, with barometric pressure of 760 mmHg
  • At 3,658 m / 12,000 ft, barometric pressure drops to 483 mmHg → ~40% fewer oxygen molecules per breath
  • Your body compensates by breathing faster and deeper
  • Pulmonary artery pressure increases
  • Production of red blood cells increases
  • Enzymes that improve oxygen transfer are produced
  • Above 5,500 meters (18,000 ft), acclimatization is not possible, and serious health risks increase

Acclimatization Strategies

How to help your body adjust to high altitude

Ascend Gradually

The main cause of AMS is ascending too quickly. Take your time and follow your guide's pace.

  • Your body typically requires 1–3 days to adjust at a new altitude
  • Avoid rapid elevation gains
  • Take rest days as suggested by your guide
  • Follow the "climb high, sleep low" principle when possible

Monitor Symptoms

Pay close attention to how you feel and communicate with your guide regularly.

  • Common AMS symptoms: headache, nausea, dizziness, shortness of breath
  • Notify your guide immediately if symptoms appear
  • Stop ascending if severe symptoms develop
  • Descent is the best remedy for severe AMS

Stay Healthy

Maintain good health practices to support your body's acclimatization process.

  • Stay well hydrated (3-4 liters per day)
  • Eat regularly to maintain energy levels
  • Avoid alcohol and sedatives during the trek
  • Get adequate rest each night

Communicate regularly with your Dream Team Adventure guide about how you feel. Guides are trained to assist with acclimatization and to recognize signs of severe AMS.

Cheyne-Stokes Breathing

  • Above 3,000 m / 9,842 ft, you may experience periodic breathing during sleep, called Cheyne-Stokes respiration
  • Pattern: shallow breaths → deep sighs → pause → shallow breaths again
  • May cause restlessness or sudden feelings of suffocation
  • This is normal at high altitude
  • Diamox (acetazolamide) can help alleviate these breathing patterns (consult your doctor before use)

Final Tips for a Safe Trek

Essential practices for your mountain adventure

Stay Hydrated & Nourished

Drink 3-4 liters of water daily and eat regularly to maintain energy levels, even if you don't feel hungry.

Avoid Alcohol & Sedatives

These substances can worsen altitude sickness symptoms and impair your body's ability to acclimatize.

Dress in Layers

Temperature fluctuations are common. Layer clothing to easily adjust to changing conditions.

Use Trekking Poles

Poles provide stability, reduce strain on knees, and help conserve energy on steep terrain.

Follow Your Guide

Your guide's advice is based on experience and training. Your safety is their top priority.

Communicate Openly

Never hide symptoms or concerns. Early communication allows for timely intervention.
