Carry-On Packing List for La Paz: World's Highest

La Paz does not ease you in gently. El Alto International Airport (LPB), which serves the city, sits at 4,061 metres (13,323 ft) above sea level — the highest commercial airport in the world. Many travellers feel breathless simply walking through arrivals. La Paz city centre is marginally lower at around 3,640 metres, but even that altitude surpasses every other major city in the Americas.

Bolivia rewards visitors who plan ahead. The country contains some of the most surreal and beautiful landscapes on earth — the Uyuni Salt Flats, Lake Titicaca, the Altiplano's vast open horizons — and La Paz itself is a city of extraordinary energy, perched dramatically on canyon walls with the snow-capped peak of Mount Illimani (6,438 m) watching over it.

Airline Carry-On Quick Reference

Airline	Cabin Bag Size	Weight	Notes
Boliviana de Aviación (BoA)	55 × 40 × 20 cm	8 kg	Bolivia's national carrier; main domestic network
LATAM	55 × 35 × 25 cm	8 kg	Regional connections via Lima or Santiago
Amaszonas	45 × 35 × 25 cm	5 kg	Small regional carrier; strict limits
American Airlines	56 × 36 × 23 cm	No weight limit	Via Miami connections

Amaszonas operates smaller regional aircraft on domestic and cross-border routes and enforces a strict 5 kg limit. If using Amaszonas for any leg of your trip (including connecting to Uyuni), check your cabin bag on a scale before you go.

Altitude: La Paz Is in a Category of Its Own

Arriving in La Paz from sea level is physically shocking for many travellers. At 4,061 metres, the airport has roughly 40% less oxygen than at sea level. The human body is designed to operate at low altitudes, and the adjustment takes time.

Altitude sickness symptoms at La Paz levels:

• Severe headache
• Nausea and vomiting
• Pronounced breathlessness even at rest
• Insomnia
• Extreme fatigue
• Loss of appetite

These are normal responses to sudden altitude exposure. They are not signs that something is seriously wrong — but they do mean your first day must be gentle.

The hierarchy of altitude acclimatisation:

If you are flying directly from a low-altitude city (sea level to La Paz), the adjustment will be harder. If at all possible:

1. Spend 2–3 days in Quito (2,850 m) or Cusco (3,400 m) first
2. Arrive in La Paz and rest completely for the first day
3. Do not exercise, climb stairs quickly, or drink alcohol on arrival

This graduated approach significantly reduces the severity of altitude sickness. Flying directly from sea level to La Paz in a single day is the hardest option and not recommended if it can be avoided.

Remedies and medications:

• Diamox (acetazolamide): The standard prescription altitude prevention medication. Should be started 24–48 hours before arriving at altitude. Consult your doctor — it is not suitable for everyone (particularly those allergic to sulfonamides).
• Coca tea (mate de coca): Traditional Andean remedy available everywhere in Bolivia. Mild stimulant effect, mildly reduces breathlessness. Completely legal in Bolivia (coca leaf is not the same as cocaine).
• Ibuprofen or paracetamol: For altitude headaches, which are the most common symptom.
• Electrolytes: Dehydration worsens altitude symptoms; drink more water than usual.

Do not take sleeping pills on arrival at altitude — they suppress breathing and can worsen altitude sickness overnight.

La Paz's Climate: Cold and Sunny

The Altiplano climate is deceptive. Days can feel surprisingly warm in direct sunlight (18–20°C), but the moment you step into shade or wind, the cold becomes noticeable. Nights are genuinely cold (5–10°C year-round). The altitude makes temperatures feel colder than the number suggests — wind chill at 3,640 metres is significant.

There are two distinct seasons:

Season	Months	Conditions
Dry season	May–September	Clear blue skies, cold nights, little rain — best for travel
Wet season	November–March	Afternoon thunderstorms, some fog, but still functional

The dry season is optimal. The wet season still allows travel but the Uyuni Salt Flats transform into a mirror lake (spectacular but requires a boat rather than driving across) and some mountain roads can become difficult.

What to Pack for La Paz

Clothing — warmth without bulk:

La Paz requires real warm layers, but not extreme mountaineering gear. The goal is versatile warmth:

• 4–5 base layer tops (wool or synthetic moisture-wicking — cotton holds moisture poorly at altitude)
• 1 mid-layer fleece or light down jacket (essential — evenings are cold)
• 1 outer shell or waterproof jacket (for afternoon showers in wet season; wind protection in dry season)
• 1–2 pairs of warm trousers (wool-mix or thick travel trousers)
• Warm socks (wool recommended)
• Hat and gloves (the airport alone requires these at 4,061 m)
• Comfortable walking shoes with ankle support — La Paz's terrain is dramatic and steep

What not to bring: Heavy ski-style jackets take up carry-on space you cannot afford. A quality lightweight down jacket compresses well and provides equivalent warmth.

Sun and altitude health kit:

• SPF 50+ sunscreen — UV at 3,640+ m is intense, particularly at the airport
• UV sunglasses
• Altitude medication (prescription)
• Electrolyte sachets
• Lip balm with SPF — altitude and dryness cause severe lip cracking

La Paz Highlights

Teleférico (cable car): La Paz has one of the most extensive urban cable car systems in the world — 10 lines crossing the city and linking La Paz with El Alto above. This is both a transport system and a remarkable experience. Take the red or yellow line for the best views. No special packing needed.

El Alto Market (Feria 16 de Julio): One of the world's largest outdoor markets operates every Thursday and Sunday. An extraordinary spectacle of Aymara commerce. Use a small cross-body bag and keep valuables minimal in market settings.

Witches' Market (Mercado de las Brujas): A compact but atmospheric market in the historic centre selling traditional Bolivian medicines, herbs, and ritual items. Worth a browse.

Death Road (Yungas Road): The famous downhill mountain bike route from La Cumbre (4,700 m) down to Coroico (1,200 m). Operators provide all equipment. No special packing needed beyond clothes you are willing to get muddy.

The Uyuni Salt Flats

The Salar de Uyuni is the world's largest salt flat (10,582 sq km) and Bolivia's most famous attraction. Getting there:

• By air: 1-hour domestic flight from La Paz (LPB) to Uyuni (UYU) on BoA or Amaszonas. Book in advance; seats sell out. Note Amaszonas' strict 5 kg carry-on limit.
• By bus: 10–12 hour overnight bus. Cheaper but demanding.

Pack for Uyuni specifically:

• Very warm layers — nights on the Altiplano are well below freezing, especially at altitude
• Sunglasses rated for very high UV (the white salt reflects UV intensely — you will burn from above and below)
• SPF 50+ sunscreen
• Gaiters or waterproof boots if visiting during wet season (January–March) when the flats flood

Most Uyuni tours are 3-day overland circuits covering the flats, coloured lagoons (Laguna Colorada, Laguna Verde), and geysers near the Chilean border. Accommodation is in basic salt hotels — bring a sleeping bag liner if you run cold.

Lake Titicaca

Lake Titicaca (3,812 m) is 3.5 hours by road from La Paz. The town of Copacabana on the Bolivian shore is the main base. A border crossing into Peru (to Puno) is straightforward — bring your passport and check current entry requirements for Peru. Pack warm — the lake is vast and exposed, and the altitude makes wind feel sharp.

Bottom Line

La Paz is the most demanding altitude destination in this guide series. Plan the acclimatisation, start Diamox if your doctor approves, pack proper warm layers that compress, and give yourself a full rest day on arrival. The city and the landscapes around it — Uyuni, Titicaca, the Yungas jungle — are extraordinary. BoA enforces 8 kg in economy; Amaszonas enforces 5 kg. Weigh everything before you go.
