The first Atacama tour that I booked was to the altiplanic lagoons. The general consensus among the other travellers at Chill Hostel, was that the lagunas altiplanicas tour is a must-do among the Atacama tours. No matter who you booked with, this tour was pretty much a full day tour (early start, and includes lunch).

I thought I should do those tours that were longer first, to give myself more flexibility later for the half-day tours. I booked the tour through my hostel, because that way I would be picked up and didn’t need to go to a pick-up point. Otherwise, I’d have to shop around at San Pedro town centre and compare tours, but I wasn’t prepared to do that. Plus, they offered it in English, which is a crucial detail in Atacama, unless you’re fluent in Spanish. 

Feeling the altitude in San Pedro

I was out of sorts and grumpy after my arrival the previous day. San Pedro hadn’t felt promising. It was hot and dusty and bare, and I had a headache. I wasn’t sure if it was from caffeine withdrawal or altitude or heat – or all three.

But the mountains in the distance promised the sights I’d come here for, and I tried to fight it off. In hindsight, perhaps that’s why I took the high lagoons for my first tour. 

But in hindsight, the headache is probably why I should have put it to later.

The hostel caretaker, a sweet little middle-aged man, brewed me some rica-rica tea – a kind of Andean shrub that I later encountered on the tour. With signs and simple Spanish, he made me understand that it was good for stomachaches. It didn’t help the headache. Smelled nice, though. 

He also offered some coca leaves, to help me adjust to the altitude. After all, I had come up to 2000+ m ASL right after being at sea level for a week on Easter Island.

At the time, I was not entirely sure how different the effect of the coca leaves would be from, you know, cocaine, so I declined. I slept the whole afternoon, and felt better. 

Where are the Atacama altiplanic lagoons?

Before my trip, I had seen some images of the altiplanic lagoons from various travel blogs. But I could not quite figure out which of the photos were of what places, and where they all were relative to each other. Thankfully, at the hostel, the other travellers’ photos helped me group at least some of the altiplanic lagoons together.

The lagunas altiplanicas are the salt lagoons (salares) of the Andean high plains, or altiplana. I discovered that this is, in fact, the same region of the Andean plateau which extends to Bolivia’s famous Salar del Uyuni. There is actually a tour you can take in San Pedro to go to Uyuni by road, crossing the border into Bolivia.

Not that this was strictly necessary, for Chile’s side had its own salares. Along the route to Uyuni, there are other salt lagoons within the Chilean border that you could opt to go to instead. At one of them, it’s possible to swim (other salares might be too ecologically sensitive to allow this, or too toxic to people).

But the most popular tour in Atacama takes you to the nearer subset of these altiplanic lagoons. They are located in Los Flamencos National Reserve, south from San Pedro.

How much did it cost for the lagunas altiplanicas tour?

Price range for tours vary little in San Pedro, although if you really shop around you can find better deals. However, if you aren’t fluent in Spanish, make sure that you’re not skimping on the price only to find that your guide isn’t fluent enough in your language (usually English) to make for a satisfying tour.

For this reason, I trusted my hostel’s recommendation, since the owner is fluent in English and looked like he has a long experience hosting foreign non-Spanish speaking tourists. Unfortunately, I have forgotten the name of the tour company.

For the altiplanic lagoons tour, there are two things you need to pay for, and they’re both normally shown on the brochure. One is the tour price itself, and the other is the park entry fee. This is because a lot of these desert attractions in Atacama are also National Reserves.

In 2017, my tour cost CLP35,000. The entry fee to Los Flamencos National Reserve was CLP 5,500.

First lagoon: Laguna Chaxa

The guide double-checked his roster, counted us all out, and briefed us on the day. There would be four lagoon sites to visit, for a total of five different altiplanic lagoons. We would then break for lunch at a restaurant near a place called Socaire. The last stop is at a charming pueblo called Toconao, and then we return to San Pedro.

And we were on our way to the first lagoon. 

Salar de Atacama

When we got off at the site, there was no lagoon immediately apparent. Instead, the landscape was of the salt desert, the Salar de Atacama. The craggy field of rock and mineralised salt was interesting in its texture, but was not immediately arresting. Stretching out into the distance, the salar was flat and rocky. I could imagine it as the bed of the paleolake that had once existed in the Ice Age. 

As we walked along the path, I examined the shallow outcrops of rock by the path. Encrustations of salt covered parts of it. I was tempted to pick some off and lick it. 

But my group was far ahead, and as I hurried after them, the lagoon came into view. 

The pink flamingo lagoon

My footsteps slowed. My mind went blank. Before me was a wide, wide vista of lilac mountains seemingly stretched incongruously flat, as though touched by a bit of Dali, atop a line of pink rock, in turn atop the blue lagoon, with the beige salt flat in the foreground.

It was the most alien sight I’d ever seen. Were it not for the flamingoes dotting the lagoon, their pink-hued feathers reflecting white from the incredibly brilliant morning sun, I would have wondered if this was on Earth at all. 

Take a photo, fool. My brain finally kicked in.

I’d never been anywhere so beautiful before, that I forgot everything. In a daze, I tried my best to capture the images, knowing that I would deeply regret it if I didn’t. If it weren’t for Rachel, who suggested we take each other’s photos, I wouldn’t have any of myself there at all.

To be honest, I don’t know why I remember this lagoon as ‘the pink one’. The lagoon itself wasn’t pink. It was quite blue, actually, reflecting the clear blue sky. There was only a narrow strip of pink along the horizon. The flamingoes’ pinkness was actually quite pale in the bright sun.

But that’s how my brain remembers it – the pink one. 

The perpetually-breeding shrimp in Laguna Chaxa

There are usually decent amenities in Chile’s national parks, but not too much, such that it encourages people to forget what they’re really supposed to be coming for. Laguna Chaxa had a visitor’s centre, and I remember it because of the aquarium. 

Of course, the flamingoes were looking for food in the lagoon, and part of their diet is a particular kind of shrimp. I remember this, because the shrimp is what’s supposed to give the pink to their feathers; otherwise, the birds would just be white.

Our guide brought us to a narrow aquarium, which contained scores of wiggly many-legged creatures. Some of them looked oddly-shaped, so I looked closer. Oh, there are two attached to each other! Oh…. they’re um… mating. 

I’ve forgotten most of what the guide explained, but something he said stuck in my mind. Actually, I forgot his exact words, but I remembered my math. The life cycle of the shrimp in the lagoons is so short, that they would really need to be mating all the time

Laguna Chaxa will leave you dazed

There was a stillness at Laguna Chaxa. A kind of deadening in the air, that’s difficult to describe and a thing you cannot experience from photos and videos. Rather, it’s something you feel from your ears and the hairs on your skin.

The flamingoes moved carefully, one leg at a time, nosing in the water. The footsteps of the tourists crunch against the rock. But the sound seemed ‘short’, like in a fog. Except there can’t be fog in the driest place on earth. 

Or perhaps it was just my brain’s numbness, dialing down all other senses to take in the sight. This lagoon, of all the altiplanic lagoons, just defied my photography. It gave me some of my best landscape photos, and yet the photos – even the panoramic ones – don’t truly capture the spatial sense of its beauty. 

But it was not the most beautiful altiplanic lagoon

Piedras Rojas: The most otherworldly lagoon

Like all good fairytales, the fairest maiden is sighted, captivates, and leaves you wondering – what was her name? 

I was never completely clear what this lagoon was called, since the stop was always referred to as the Red Rocks, i.e. Piedras Rojas. But, coming from Laguna Chaxa, I did not expect to be wowed a second time. 

And then we arrived at the second lagoon.

When we got out at Piedras Rojas, its red rocks were not at all the main attraction for me. For the line of grey mountains beyond commanded attention, appearing completely un-mountainlike, impossibly soft and pastel, as if touched up like an impressionist painting. 

At its feet lay a delicately mint-green lagoon, its water’s edge lapping against fine pale sand, playing at being an ocean around an atoll. There was an alien simplicity to the scene, and I was completely charmed. 

Our guide spoke about the minerals that gave the mountains its unusual colouring, but I was too mesmerised to remember it, even though this is the sort of thing that I usually like to learn. All I could remember was that the white powdery brush-strokes at the base of the dreamy hills was borax, blown up the slopes by the winds of the high plains.

What planet is this?

Windchill on the high plains of Atacama

I would gladly have stayed by the water’s edge throughout all the time allotted for this stop. However, the chill mountain winds gusting constantly across the lagoon was much colder than I expected. 

I knew beforehand that I’d have to carry some kind of warm clothing, going up to the altiplanic lagoons. But when you’re in San Pedro, feeling its daytime desert heat, it’s hard to gauge just how warm you should aim for. I had a solid windbreaker, after all. Surely it was enough to, you know, break the windchill? 

No, it was not.

I thought forlornly of the winter cardigan back at the hostel, for I had begun my round the world journey in cold Netherlands. I had my backup scarf with me, but unfortunately I had only packed the silk one – not the cashmere that I acquired from my host in Pokhara, which would have been really handy. 

It was no good. I retreated into the van, and continued gazing at the alien lagoon from within.

Aguas Calientes: The salt marsh lagoon

The third lagoon on the tour was not far from the fairy-alien one, yet it was decidedly an earthly lagoon. As the name implied, a hot spring welled up here.

Since the water was sufficiently non-toxic (i.e. without the borax and whatnot), a marsh ecology was able to grow around the lagoon. Our guide motioned for us to come to where he was squatting. Different from pretty much all other places thus far in the Atacama desert, the ground was actually muddy. Algae made for slippery footing, and reeds grew thick around. 

It was the hot spring. At his invitation, we touched the water. It wasn’t actually very hot. More lukewarm, to be honest.

The hot spring was just lukewarm

This lagoon was different yet again from the first two, even without considering the yellow of the salt marsh. Its blues were cobalt and aqua, perhaps indicating different depths, interspersed with fingers of land criss-crossing the landscape like an estuary. Except that it was far inland, and at altitude.

The far hills were tinged red, giving a slight mauve tone to the mountain background. The air was different, more moist. There was just a whiff of organic scent, of submerged biomass decaying, of soil and the breathing rushes. 

Another of His signs is this: you see the earth lying desolate, but when We send water down to it, it stirs and grows. ~41:39

And I realised something very strange, and deeply profound, as I stared longer at the beautiful, earthbound lagoon of gold and blue. It was not as otherworldly as the gorgeous fantasy lagoon at Piedras Rojas.

But I realised, the most beautiful lagoon was not my favourite lagoon. Inexplicably, this lukewarm salt marsh lagoon, was my favourite.

Miscanti & Miñiques: The highest altitude lagoons

We headed to the final stop on the lagoon tour, which actually comprises of two altiplanic lagoons – twins, you might say. These final two lagoons has the distinction of being the highest altitude altiplanic lagoons in Atacama. My headache had returned sometime at Piedras Rojas, and it was growing steadily worse. 

To heck with it. I dipped into the stash of coca leaves in the van, tentatively chewing on three, hoping it would help. 

Laguna Miscanti could be seen from afar, although it was quite a walk to actually get close. Unlike the previous two lagoons, but similar to Laguna Chaxa, you cannot get right up to the water’s edge. The designated path maintains a viewing distance, but even then you can’t really fit all of the lake in frame. 

That’s not to say it was a big lake, though. The final two altiplanic lagoons were the only two on the tour that you could see the whole of, when you’re looking at it in person.

Lagunas Miscanti and Miñiques were too simple to challenge the other lagoons in beauty. The colour of the water was their most special attribute – a deep sapphire blue, with a slightly teal cast. The mountain peaks around them had traces of snow even in December. At the right angle, you could see the Lascar volcano far beyond in the distance.

Yet, they somehow seemed the most alien, in the sense of the ‘most sci-fi’. Something to it feels like it’s straight out of the old space alien landing movies. I wouldn’t bat an eyelash if a UFO were to land here. 

At >4000m ASL, its entire surroundings were almost completely bare. But astonishingly, there was life up here, and I don’t mean the grass clumps. A tiny bird flitted about on the ground amongst the rocks and onto the path.

You can get altitude sickness in the altiplano

I was halfway around Miscanti before I realised I was experiencing altitude sickness. The headache had not only gotten worse, but my heart was also working a lot harder. I was beginning to doubt that I could remain conscious. 

I had not really thought much about altitude, because I felt so much better after my nap the previous day. Besides, I had been up to 4000m ASL before, and hadn’t really needed my altitude sickness pills then.

However, there by the teal-blue lake, I belatedly realised an important distinction. In Annapurna, I ascended from ~2000m to 4000 over seven days of acclimatisation. Here, I had just done the same ascent in a van in less than half a day. Not to mention, in an arid landscape too. My Nepali guide Devi had constantly nagged me about hydration, since it supposedly protects against altitude sickness

The van was far away at this point. Inconveniently, I was exactly halfway along the walk. Whether I turned back or continued to Miñiques, it would be the same distance. Rachel doubled back to see why I lagged, and I managed to tell her the problem. Not that she could do anything about it; but at least if I passed out, someone knows.

Well, let’s get on with it then. Thinking back to all of Devi’s reminders, the best thing I could do was to pause, wait until my heart rate returned closer to normal, and then go super slow. And just breathe. Breathe.

Geeking out at the Tropic of Capricorn

We stopped for lunch an hour later near Socaire, after which I felt better. On the way back down from the high lagoons, I lost all concerns of potential cocaine addiction, and chewed freely on the coca leaves. Disappointingly, I didn’t feel any different, and concluded that the leaves are not at all the same as the drug. (Though that didn’t stop me from scandalising my mother with tales of munching on coca).

The final stop of the tour was the village of Toconao, but there was one special quick stop before that. The van pulled over at a seemingly random spot on the road, but as we got out, I saw the sign and squealed! 

For real? We’re at the tropic of Capricorn?

It had not crossed my mind at all that the tropic line would cross Atacama. (Although it probably should have, given that the tropic of Cancer in the opposite hemisphere tends to be ‘deserty’). Rachel asked me what the tropic of Capricorn was, but at the time I couldn’t remember enough astronomy to explain.

But here goes. Basically, it’s the southernmost latitude where it’s possible for the sun to be directly overhead, and this occurs on the December solstice. (Flip it to the June solstice for the tropic of Cancer).

It’s not yet the solstice though!

The charming town of Toconao

When you arrive in Toconao, you immediately understand why it’s a tourist stop. It is the cutest little South American town – downright stereotypical, in fact! The moment I saw it, I immediately thought, ‘pueblo’! (Admittedly, this association may have been shaped by Hollywood depictions of Mexican towns in the daytime series of Zorro watched in childhood, whereas Chile is much further south than that.) 

There was the paved stone street, and the stone buildings. The whitewashed church tower with its cactus wood door. The colourful knitted quilt oddly wrapped around the trees. The vibrant woollen ponchos with Andean motifs hanging outside the stone souvenir shops. 

It was adorable. I wish I hadn’t been so tired. I wasn’t even in the mood for ice cream. But I suppose being too tired to shop saved me a heck of a lot of money.

Carbon offset information to Atacama Desert, Chile

I went to Atacama Desert as part of a longer journey around the world. Visiting Atacama Desert specifically, assuming return flights from Kuala Lumpur to Calama via Sydney and Santiago, produces carbon emissions of approximately 15,383 lbs CO2e. It costs about $77 to offset this.

  1. Oh my god… unreal is definitely the right word for this! What a really gorgeous place! Seeing those flamingos is already breathtaking, but that lagoon at Piedras Rojas (seriously, I wonder what the name is, haha) is just… wow. I’ve got no words. You’re really fortunate to have gotten the chance to go on this trip! Thanks for sharing it with us!

      It was one of those places you can’t really capture in words or even images – especially if where you’re from is totally unlike this (like me). Like another planet. Not an exaggeration.

  2. Natalie says:

    What a beautiful place! I have always wanted to see flamingo’s in the wild!

    • Teja says:

      It’s stupid beautiful. As in, stupefying… Don’t take a half day tour for the high lagoons – you’ll want a bit of time at each one, and you’ll want them all.
