3-Month South America Packing List: What to Bring

Introduction: 3-month South America packing list

When we planned our 3-month trip through South America, it was from January to March, meaning summer in the Southern Hemisphere. The plan was ambitious: start in São Paulo, follow Brazil’s coastline down to Uruguay, take the ferry to Buenos Aires, explore Argentina all the way to Patagonia, cross into Chile, and eventually reach Ecuador and Colombia before looping back to Brazil through the Amazon.

That was the idea, at least — but as we usually travel without a fixed plan, we knew things could change along the way.

This journey meant packing for everything: humid tropical weather in Brazil, windy beaches in Uruguay, and the cold mountain air of Patagonia. Finding the right balance between comfort, versatility, and weight was key.

Here’s our complete 3-month South America packing list — what to bring, what to skip, and how to pack light across all climates. — and what we learned after 3 months of traveling across South America.

South America Packing List in detail

Backpacks Packing List

Your backpack is your travel home — and when you’re moving every few days, comfort, size, and organization matter more than anything. You’ll be walking with it, lifting it into buses, or carrying it up hostel stairs.

What we packed:

• 50L backpack (main pack)
• 1 rain cover
• 1 foldable daypack (replaced by a sturdier 20–22L hiking pack later)

Tips:

• 50L is the sweet spot for a 3-month trip — enough space without being overwhelming (and it should fit inside planes’ overhead compartments)
• Invest in a comfortable harness and waist belt. It makes long transfers way easier.
• If you plan to hike, get a real daypack (not a foldable one). It’s worth it for comfort, support, and ventilation.
• Don’t forget a rain cover — sudden storms are common, especially in Patagonia and the Amazon.

Top and chest Packing List

Packing clothes for 3 months in South America means dealing with hot, humid jungles and cold, windy mountains — sometimes in the same week. The key is layering and choosing multi-purpose, quick-dry materials.

Jackets

• 1 rain jacket
• 1 warm mid-layer hoodie or down jacket
• 1 lightweight foldable jacket

Tips:

• Patagonia and the Andes can be cold even in summer, so always bring one warm layer.
• A rain jacket is a must — it also doubles as a windbreaker.
• The foldable jacket is great for city days or chilly evenings when you don’t want to look too “hiker-style.”

Tops

• 3 tank tops
• 3 regular t-shirts
• 3 merino wool t-shirts

Tips:

• Merino wool is your best friend: breathable, odor-resistant, and dries super fast. You can wear it multiple days in a row without smelling (true story).
• Skip cotton — it takes forever to dry in tropical weather.
• Tank tops are great for hot days, especially in Brazil or northern Argentina.

Bottoms & Legs

You’ll walk a lot, climb a lot, and sit on countless buses. Choose pants that are light, flexible, and easy to wash.

What we packed:

• 9 + 1 underwear
• 2 merino socks
• 2 long socks
• 5 short socks
• 1 base layer
• 2 + 1 × hiking pants
• 1 comfy pant (for sleep or long rides)
• 2 shorts
• 2 swim shorts

Tips:

• Don’t bring too many hiking pants — 2 is plenty.
• Convertible pants (that turn into shorts) are great space savers.
• Patagonia is windy — keep one pair of long, windproof pants for hikes.
• Quick-dry underwear and socks are gold when you’re doing laundry every few days.

Tip: We never needed the base layer — even Patagonia wasn’t that cold in February.

Footwear Packing List

Shoes take up the most space and weight, so pick wisely. Think versatility: one pair for hiking, one for everyday use, one for relaxing.

What we packed:

• 1 flip-flops
• 1 Adidas sneakers
• 1 hiking boots

Tips:

• Flip-flops are great for showers, beach days, and letting your feet breathe.
• Sneakers are perfect for city walks and casual days.
• If you’re planning multi-day hikes (like Torres del Paine or El Chaltén), invest in good hiking boots — your feet will thank you.
• For lighter trips, trail running shoes can replace hiking boots.

Head & Hands

Don’t underestimate the sun or the wind — both can be strong in South America.

What we packed:

• 1 Peruvian hat (souvenir + warmth)
• 1 merino hat or under-hat
• 1 thin gloves

Tips:

• Bring a cap or hat for sun protection — UV levels can be extreme in the Andes.
• Thin gloves are enough for summer in Patagonia; if you go in winter, you’ll need warmer ones.

Health & Care

Pharmacies are easy to find in South America, but it’s best to bring your essentials to avoid the stress of explaining your symptoms in another language.

Medicine

• 3 malaria medications
• 2 stomach remedies
• 1 Imodium pills
• 1 Imodium chewable
• 1 Doliprane (pain relief)
• 2 UPSA (cold medicine)

Tips:

• Always carry Imodium or similar — food changes can be tough on the stomach.
• In the jungle or Amazon areas, malaria prevention is worth considering.
• Don’t forget a small first aid kit (plasters, antiseptic wipes, etc.).

Toiletries

• 1 toothbrush
• 10 Condoms
• 1 dry deodorant
• 1 dry soap bar
• 1 nail cutter
• 1 sewing kit
• 1 electric shaver + charger
• 4 big wet wipes + 1 small pack
• 2 tissue packs

Tips:

• Use solid toiletries (soap, shampoo, deodorant) to save space and avoid spills.
• Wet wipes are lifesavers on long bus rides.
• Condoms can be surprisingly expensive or low-quality in some countries — bring your own.

Towels

• 1 small beach towel
• 1 microfiber towel

Tips:

• A microfiber towel dries 5x faster than cotton and takes up no space.
• A small beach towel doubles as a picnic mat or bus-seat cover.

Electronics & Miscellaneous

South America is pretty well-connected, but power outages happen, and outlets differ slightly by country. A small, reliable tech setup is ideal.

Electronics

• 1 solar battery charger
• 1 phone charger
• 1 earphone charger
• 1 Bluetooth earphones
• 1 wired earphones (backup)
• 1 headtorch

Tips:

• A solar power bank is perfect for long hikes or camping.
• Bring both Bluetooth and wired earphones — wired ones are handy for buses and planes.
• A headlamp is essential for power cuts or early morning hikes.

Other Essentials

• 1 mosquito spray (for skin)
• 1 mosquito spray (for clothes)
• 3 medium compression bags
• 2 small compression bags
• 1 small extra bag

Tips:

• Mosquito repellent is a must in Brazil, the Amazon, and northern Argentina.
• Compression bags help keep dirty clothes separate and organized.
• A small foldable bag is handy for groceries or beach days.

After 3 Months on the Road

Looking back, we were really happy with what we packed. Nothing major was missing, and we didn’t feel overloaded.

If we could change anything, we’d:

• Start directly with a real hiking daypack instead of a foldable one.
• Skip one hoodie and one hiking pants to save space.
• Leave the underpants at home — it never got cold enough.

Traveling light made our days easier, especially when hopping between buses, hostels, and airports. Our South America packing list turned out to be the perfect balance between comfort, flexibility, and minimalism — ideal for a 3-month backpacking adventure across the continent.
