How bad will I feel the first day?

Most people experience headaches, fatigue, and mild nausea. It's like a hangover plus exhaustion. This is normal at 12,000+ feet. Severe symptoms like vomiting, confusion, or trouble breathing require immediate medical attention.

Can I skip the acclimatization and just power through?

Absolutely not. Rushing at altitude can lead to serious altitude sickness that requires evacuation to lower elevations. Many travelers who 'power through' end up bedridden for days or cutting their trip short.

When can I drink alcohol safely?

Wait at least 5 days, preferably a full week. Alcohol hits much harder at altitude and severely dehydrates you. Your first drink will feel like you had three at sea level.

Should I take altitude medication?

If you've had altitude sickness before or are particularly concerned, acetazolamide (Diamox) can help. Start taking it 1-2 days before arrival. Consult your doctor first — it's prescription-only in most countries.

What if I feel worse on day 3 than day 1?

This can happen as cumulative effects build up. If symptoms are getting significantly worse rather than gradually better, descend to a lower altitude immediately and seek medical attention.

How to Plan Your First Week in La Paz for Proper Acclimatization

Spend your first week in La Paz taking it extremely slow — sleep, hydrate constantly, and avoid alcohol. Plan only 1-2 gentle activities per day for the first 3 days, then gradually increase activity as your body adjusts to 12,000+ feet of elevation.

Arrive and go straight to your accommodation. Take a taxi from El Alto Airport (don't walk with luggage at this altitude). Check in and rest for 2-3 hours minimum. Your body is now working 40% harder than at sea level.
Drink water obsessively for 48 hours. Aim for 4-5 liters per day. Buy bottled water or use purification tablets. Dehydration hits faster and harder at altitude. Keep a water bottle with you at all times.
Eat light, frequent meals. Your digestion slows at altitude. Stick to simple carbs, fruits, and vegetables. Avoid heavy proteins and dairy for the first 2-3 days. Coca tea helps with nausea and headaches.
Plan maximum 2 gentle activities for days 1-3. Walk around San Pedro neighborhood, visit nearby markets, or take the Mi Teleférico cable car (sitting down transport). Avoid hiking, intense walking, or anything strenuous.
Sleep 9-10 hours per night. Your body needs extra rest to produce more red blood cells. Don't fight fatigue — embrace it. Nap during the day if needed.
Test your limits gradually on days 4-7. Try longer walks around the city center. Visit museums or markets that require more walking. If you feel good, take a day trip to nearby Lake Titicaca (same altitude).
Skip alcohol completely for 5 days. Alcohol dehydrates you faster and amplifies altitude sickness symptoms. Your first beer will hit you like a truck anyway. Wait until day 6 minimum.
