First Time in South America? A Complete Travel Guide to Prepare Before You Go

Many people say South America is their dream trip… but nobody warns you just how much it will test you along the way.

This continent has the driest desert on earth, mountains high enough to make breathing difficult, and trekking trails so beautiful you forget how tired you are — each destination demands a different kind of preparation.

We’ve been there, from Atacama to Santiago, and learned things the hard way so you don’t have to — here’s everything you need to know before you book that flight.

What to Prepare Before Traveling to South America

1. Visa — Check Early Because Every Country Is Different

Thai passport holders don’t need a visa for Peru, Chile or Argentina but some countries require documents prepared in advance. Before booking anything, check that your passport has more than 6 months validity remaining, confirm visa requirements for each country on your itinerary, and always carry proof of onward travel — some border officers do ask.

• Passport valid for more than 6 months
• Visa requirements per country
• Proof of onward travel — some borders check this

Visa rules change frequently. Always verify with the relevant embassy before travel.

2. Flights — Plan Early Because It’s Far and Expensive

Flying from Bangkok to South America takes 20-30 hours or more with 1-2 stopovers in cities like Doha, Dubai or Europe. The earlier you book, the better the price.

Key things to check:

• Book at least 3-4 months in advance
• Compare prices on Google Flights or Skyscanner
• Check baggage limits on domestic South American airlines — many allow only 7-10kg carry-on

3. Travel Insurance for South America — Non-Negotiable

Travel insurance for South America is essential. Many areas are extremely remote, and emergency evacuation costs can be shocking if something goes wrong far from a city.

Good coverage for this trip should include:

• Medical expenses and emergency evacuation
• Trip cancellation
• Adventure activities if trekking or hiking is in your plans

4. South America Packing List — Pack for the Terrain

What you pack for South America depends entirely on where you’re going. You can experience both heat and cold in a single day, especially at altitude or in the desert. Layering is far more practical than one heavy jacket.

Layered clothing — moisture-wicking base, insulating mid-layer, windproof outer layer. Works for every situation.

Hiking boots — if trekking is in your plans, regular sneakers won’t cut it. We tried it and ended up with a sore ankle in Patagonia. The difference is significant.

Sunscreen SPF50+ — UV intensity at altitude and in the desert is much stronger than normal. Apply and reapply.

Universal Travel Adapter — Covers every country in one trip, no need to buy multiple adapters.

Power Bank 20,000mAh — On full-day hikes with no charging points, a high-capacity power bank is essential. Pack a spare charging cable too — replacements are expensive to buy locally.

Phone Lanyard — In some South American cities, keeping your phone visible on a table or taking it out of your bag frequently is not ideal. A lanyard keeps it on you at all times without thinking about it.

5. Health Before Traveling to South America — The Most Overlooked Part

Altitude sickness is what most South America travelers underestimate. If Peru, Bolivia or anywhere above 3,000 metres is on your itinerary, your body needs time to adjust.

What helps:

• Rest for 1-2 days after arriving before any physical activity
• Drink plenty of water
• Coca tea is widely available and genuinely helps
• Consult a doctor about medication before you go

Yellow fever vaccination is another thing people often forget. Some countries like Brazil and Bolivia require proof of yellow fever vaccination before entry. Get vaccinated at least 10 days before departure and keep your certificate with your passport throughout the trip.

Always consult a doctor or travel health clinic before departure.

6. Money and Payments in South America

Carry both card and cash. Visa and Mastercard work fine in major cities but remote areas are cash only. US dollars are useful as some countries accept them more readily than local currency. Always notify your bank before traveling.

Where to Stay in Santiago — The City Most People Just Pass Through

Santiago is often the first or last stop on a first South America trip. If you’re looking for a well-located place with good atmosphere, Ventana Sur Hostel is one we recommend from personal experience.
