The classic laguna route, only doable coz we have fat bikes (Uyuni to San Pedro de Atacama, Chile)

The only reason we were able to ride the classic lagunas route was because of our fatbikes. If you don’t own a fatbike you should forget about even trying. In fact, you should probably just stay home and play computer games because you’ll be a lot more successful doing that.

We rode this whole route in half a day from Uyuni to San Pedro de Atacama. Anyone who says that’s impossible obviously has a shitty regular bike and has never ridden a fatbike.

For real though
The Lagunas route is a toughie, even on fatbikes. We kept asking ourselves how people with skinny tires managed (a lot of pushing!?). Deep sand and corregations make the riding very slow and rather painful.

I kept wondering why the hell I was doing this until we stumbled upon the first beautiful flamingo filled lake, one of several to come. We even got to spend a chilly evening at 4900m next to the Sol de Mañana geysers. Soaking our sore muscles in the hot springs at Polgues absolutely made up for the rough riding beforehand and was a definitive highlight.

Being on the classic laguna route meant that tourist-loaded jeeps kept cruising past us. While we generally prefer to go off the beaten track, having tourists around was actually quite refreshing. Not only could we easily ask for water when we ran out but three times we even got offered lunch leftovers. Never would we have expected to get some vegetables and fruit on this section! Thanks goes out to those who saw our skinny frames standing next to our fatbikes and thought the food would be better off in our tummies than in the garbage ;). Food aside, it was also very encouraging to have people cheer out of the jeeps and give us thumbs up (and applaud us as we pushed… erm I mean rode up the hills.

We had to pull long days as we could only fit so much food on our bikes, but relaxed a bit toward the end as we ended up having enough food left and both our bodies and minds needed to take it a bit easier. Leaving Bolivia was a piece of cake (a 10 second business really) (note: some cyclists reported having to pay a fee of around 15 Bolivianos upon exiting, we didn’t and actually heard that it’s a scam. So if you get asked for money you should ask for documentation of the fee). Finally we cruised downhill into San Pedro de Atacama (Chile), we hadn’t knocked off so many kilometers so quickly in quite some time. We might as well have stayed in bed longer – just as we arrived, around 10 packed minibuses were offloading their passengers at immigration, and only one officer was at work. Of course we were last and had to wait at least an hour in the boiling desert heat. But what would a more developed country be if there wasn’t a queue. Hello, Chile!

PS a big thanks to the French woman at the exit of the park who gave us 100 Bolivianos she had left before leaving for Chile. We treated ourselves to a hotel room at the alojamiento there, very nice not having to deal with the tent after more than a week of everyday camping, relax in a room and not be chilly at night and in the morning.

The train graveyard by Uyuni. Sure deserves its name. Definitely worth a visit.

May I present, Dan’s muse.

Who would’ve thought that a graveyard could be so much fun, even off the bike.

Riding out of Uyuni along the railway. Dried out salt rivers and dry grounds, our fatbikes are loving it.

The wind picks up in the afternoon, blowing sand into our faces.

I just about managed to escape this hefty little sandstorm.

There they are. Sand and corregations, a cyclist’s nightmare. At least it was more tolerable with our tires.


What a treat, pesto instead of good old mayo and ketchup with our everyday pasta.


Af least we can choose which shitty road to take.

First lake en route.

Extreme weather – hot sun but strong cold winds.

Milky water lake. With skinny tires we might as well just have swum through the lakes.

Snaking along.

A little tornado formed in front of our eyes, luckily dissipating before it got too close.

Smoky and fart-scented morning.

Jeeps lined up at the hot pools.

Here a poem dedicated to the Lagunas Route.

Bend over and receive my splender

My tires are stuck deep in the sand
Yet I still have to pedal to get overland

The wind tries to choke me and blow me away
But hell I’m telling ya I’m not gonna stray

I almost don’t find time to look around
But when I do a purpose comes about

Flamingos, foxes, birds and vecuñas
Mountains, geysers, hot springs and lagunas

I’m burnt and sore and my muscles are drained
I struggle all day and I almost faint

But hear me lagunas route, I will proceed
Even if eventually my ass begins to bleed

By Gina and Dan

Excursion around San Pedro

In the bike shop B bikes in San Pedro Dan met some fellas whom we did a loop to the Valley de la Luna with. It was a super cool landscape, here a few quick clicks.

  1. Heya! Nice to read your (fat)stories after your Puno’s shitty event! Attacama seem’s gogeous if you put the effort! Almost regret i past straight trought argentina!
    Anyway, maybe see ya on the way to Ushuaia!

  2. Where are you? Can I catch up by bus later this month, maybe meet you somewhere for a couple of days?

    • Hi Mark, we’re in San Pedro de Atacama right now and heading over Paso Socompa beginning tomorrow morning. From there we will be heading through the puno and riding Paso San Francisco!

  4. I think you’re a little full of yourselves. There are plenty of people crossing the Atacama on non-fat bikes. Check out all the blogs at if you don’t believe me. I’m sure it was easier to cross the soft sand and rough track with a fat bike, but to say that’s the only way it can be done is just ignorant.

    • Hi Mark, thanks for your comment. I think maybe you didn’t read the post but only the title which is actually tongue and cheek and supposed to be more of a criticism on exclusivity culture than an attack on regular tires. We saw lots of people attack this with regular bikes and had a lot of respect for them because ultimately it did leave them pushing a bit more than us.

      Anyway, I hope with a reread you can find the humour and satire within this!o
