How Many Days in South America? (From a Travel Planner)

How Many Days Do You Need In South America?

South America is roughly twice the size of Europe. The distances between countries are vast, and journeys that look short on a map can still take half a day once you factor in airports, transfers and check-in times.

That’s the thing most people don’t account for when they start planning.

A four-country trip in three weeks sounds achievable until you realise 5 full days are spent moving rather than enjoying the places.

The sweet spot for most first-time visitors is four weeks.

This is enough time to do two or three countries properly, hit the highlights that matter most, and actually feel like you’ve been somewhere rather than just passed through.

Here’s a quick summary of what’s achievable: 

South America Trip Length	No. of Countries	Avg. Cost Exc. International Flights ($)	Best For
1-2 Weeks	1	£800 – £1,600	One country done properly
3-4 Weeks	2-3	£2,400 – £3,200	First-time visitors wanting to see the highlights of a region i.e Patagonia
5-6 Weeks	3-4	£4,000 – £6,000	A full region, the Central Andes or Brazil, Argentina and Chile. Or a fasted paced highlights tour.
2-3 Months	4-7	£6,500 – £10,000	North to south, covering most of the continent
4 Months +	8+	£12,000+	Digital nomads or sabbaticals

Once you’ve worked out how long you need, the next decision is when to go, my best time to visit South America guide covers the seasonal windows by country and trip length.

Is One Week In South America Worth It?

Honestly, with the cost and distance of international flights to get here, one week is hard to justify. By the time you factor in the journey itself, you’re losing a day or two at each end just to travel.

That said, if one week is all you have and you’re set on going, it can work, but only if you stick to a single country and resist the temptation to cram more in.

Buenos Aires, Rio de Janeiro, or Colombia’s Caribbean coast are all strong standalone options that give you enough to fill a week without feeling rushed.

Just don’t try to fit in multiple countries.

You’ll spend more time in airports and on buses than you will actually experiencing the places you’ve come to see.

Is Two Weeks In South America Enough?

Two weeks is the minimum I’d recommend for a proper visit to South America.

It’s enough to see one country or two at a reasonable pace, as long as you choose ones that sit close together geographically and take internal flights rather than long bus journeys between them.

What two weeks won’t give you is a north-to-south trip covering multiple regions. If that’s what you’re picturing, you need more time.

One thing worth knowing: with two weeks, transit days matter more than on a longer trip. Every day spent travelling is a higher proportion of your total time. Keep the route tight, prioritise flights over buses for longer stretches, and don’t try to squeeze in more than two countries.

For example, Quito, the Galápagos Islands and Machu Picchu can be done in two weeks and you’ve ticked off two of South America’s biggest highlights in one trip.

Take a look:

Day	Where?	Highlights
1-2	Quito	Walking Tour, Teleferico Cable Car
3-7	Galapagos Islands	Snorkelling, Giant Tortoise Sanctuary,
8-11	Cusco	Rainbow Mountain, Sacred Valley
12-13	Aguas Calientes	Machu Picchu
14	Lima	Miraflores, Barranco

Want more detail on two-week itinerary options? For more options, here are five two-week South America itineraries worth considering.

How Much Does Two Weeks In South America Cost?

As a rough rule, budget a minimum of £700 per week for a South America trip. That covers mid-range hotels, local transport, meals and basic activities.

On top of that, factor in internal flights and major activities separately.

That figure can vary significantly depending on where you go. Patagonia and the Galápagos Islands will push costs up, while Colombia and Peru tend to come in under that figure.

Overall, I would say a budget of £2000 – £2500, excluding international flights will cover most two week trips.

Is Three Weeks In South America Enough?

Three weeks is a good amount of time, but it still has limitations that are worth being honest about.

My recommendation for three weeks is stick with two countries rather than three.

It might feel counterintuitive with 21 days to play with, but once you factor in transit days, internal flights and the time it takes to actually settle into a place, three countries in three weeks means spending too much time moving and not enough time being somewhere.

Three weeks also opens up the possibility of slowing down. Rather than adding a third country, use the extra time to spend longer in the places that earn it.

Here’s a successful client route that focused on a single country:

How Much Will Three Weeks In South America Cost?

As a rough rule, budget a minimum of £700 per week for hotels, food, local transport and basic activities. For three weeks that’s a baseline of £2,100.

On top of that, factor in internal flights and major activities separately. A Machu Picchu entry, the Belmond train from Cusco to Puno, and a Uyuni Salt Flats tour, can each add £300-£500 to your budget.

A realistic total for three weeks in South America, excluding international flights, is £2,500 to £3,500 depending on your route and what you want to do.

Is One Month In South America Enough?

One month is the sweet spot. It’s the most common trip length I plan, and for good reason – four weeks gives you enough time to do one full region properly without feeling like you’re constantly on the move.

With a month, you’re looking at two to three countries done at a pace that actually lets you experience them.

What one month gives you that shorter trips don’t is breathing room.

Here’s a client case study showing how to plan 3 countries across 4 weeks:

How Much Will One Month In South America Cost?

Using the £700 per week baseline, one month comes to roughly £2,800 before internal flights and major activities.

Add those in and a realistic total budget for one month, excluding international flights, is £3,500 to £5,000 depending on your route.

A four week route that focuses on Peru, Bolivia and north Chile will be closer to £3,500.

A four week route that goes from Brazil down to Patagonia will be closer to £5,000.

Is Five To Six Weeks Enough For South America?

Five to six weeks is where the trip really opens up. It’s the minimum I’d recommend if you want to combine the Andes and Patagonia on the same trip, and it’s the sweet spot for a proper South America highlights tour.

With six weeks you can realistically cover Peru, Bolivia, Northern Chile and Patagonia in one route, hitting Machu Picchu, the Uyuni Salt Flats, the Atacama Desert and Torres del Paine without feeling like you’re rushing any of them.

Five weeks is tighter but still workable.

The key is being selective – pick the highlights that matter most to you rather than trying to tick everything off.

Here is an example of a 6-week route that covered the major highlights of the continent:

• How To Spend Six Weeks In South America

How Much Does Five To Six Weeks In South America Cost?

At £700 per week baseline, five to six weeks puts you at £3,500 to £4,200 before internal flights and major activities.

A realistic total for a highlights tour of this length, excluding international flights, is £4,500 to £6,000.

A route that includes Patagonia, Machu Picchu and the Uyuni Salt Flats will sit toward the higher end given the internal flights and activity costs involved.

Is Two Months Or More Enough In South America?

Two months is where you stop ticking off highlights and start actually travelling. The pace changes, the experience changes, and you begin to understand the continent rather than just see it.

With two months, a north to south route covering most of the continent’s highlights becomes genuinely achievable.

That’s seven countries, most of the major highlights, done at a pace that doesn’t feel like a conveyor belt.

The honest caveat: two months is a long time on the road.

Most of my clients who do two months or more are either taking a career break, planning a sabbatical, or have been to South America before and want to go deeper. If that’s you, it’s one of the best things you can do.

Three months and beyond is really the territory of slow travel, spending two to three weeks in a single country rather than passing through in five days.

The continent rewards that approach if you have the time.

Here’s Kathy and John’s trip that saw most of the continent:

How Much Does Two Months Or More In South America Cost?

At £700 per week baseline, two months puts you at roughly £6,000 before internal flights and major activities.

So a realistic total for two months, excluding international flights, is £7,000 to £10,000 depending on pace, route and travel style.

Slower travel often costs less per week since you’re not constantly paying for new accommodation, internal flights and onward transport.

Travellers who slow down in cheaper countries like Colombia, Peru or Bolivia can come in close to the baseline figure of £7,000.

But spending longer in Chile, Argentina and Brazil or adding more unique experiences will push you closer to £10,000.

How Many Countries Can You Visit In South America?

This is one of the most common questions I get, and most people approach it the wrong way.

They start with a list of countries they want to visit and then try to fit them into whatever time they have. It rarely works.

A better way to think about it is this simple formula:

take the number of weeks you have, subtract one, and that’s the number of countries I’d recommend.

Weeks – 1 = Number of countries

• 2 weeks = 1 country
• 3 weeks = 2 countries
• 4 weeks = 3 countries
• 5 weeks = 4 countries
• 6 weeks = 5 countries

The reason for subtracting one is simple.

South America’s distances are vast, and every country transition costs you time – internal flights, border crossings, getting your bearings in a new city. That lost time has to come from somewhere, and it usually comes from the places you actually wanted to see.

Removing a country from the route will always make your budget go further as well.

If you want to slow the trip down ever more and do a deep dive into less countries, then N – 2 is a better rule to stick to.

How To Complicate Your South America Trip

One combination I get requested a lot is Peru and Brazil. I understand the appeal – people want Machu Picchu and Iguazu Falls on the same trip, and on a map it doesn’t look that far apart.

The reality is different.

Getting between Machu Picchu and Iguazu Falls requires three to four flights and the best part of two days in transit.

Most people don’t realise that until they start booking, by which point they’ve already committed to the route.

It can be done, and I’ve helped clients plan it, but I always push back first. If you have four weeks or less, you’ll almost always get more out of choosing one or the other and doing it properly than trying to squeeze both in.

What’s The Best Length For A First South America Trip?

If you’re visiting South America for the first time and you’re asking me directly, my answer is four weeks.

Four weeks gives you enough time to do one region properly without feeling rushed. It’s long enough to get over the jet lag, settle into the pace of travel, and actually enjoy the places you’ve come to see rather than just passing through them.

The two routes I recommend most for a first four-week trip:

• Peru, Bolivia and Northern Chile – Machu Picchu, the Uyuni Salt Flats and the Atacama Desert in one connected overland route
• Brazil, Argentina and Chile – Rio, Buenos Aires, Iguazu Falls and Patagonia, best done October to April

It’s also the length where the planning starts to make sense. With four weeks you can build a logical, connected route, keep the internal flights to a minimum, and still hit two or three of the continent’s biggest highlights.

If you can stretch beyond four weeks, even by a few days, do it.

The difference between four weeks and five weeks in South America is significant – that extra days spread out across the trip slows it down to a great pace, or its another chance for a final highlight.
