The O-Circuit in Torres del Paine: Complete Budget Backpackers Guide
If you are traveling South America on a tight budget and looking for one of the most spectacular treks on Earth, the O-Circuit in Torres del Paine National Park should be high on your list.
For 8 days I hiked through brutal Patagonian winds, along massive glaciers, past turquoise lagoons, and over mountain passes surrounded by jagged granite towers. The trail pushed me physically, but it also delivered some of the most incredible landscapes I have ever seen!
This guide covers everything a budget backpacker need to know about hiking the O-Circuit: cost, logistics, itinerary, food planning, gear, and my personal experience completing the loop.
What is the O-Circuit in Torres del Paine?
The Torres del Paine O-Circuit is a 80 mile (130 km) loop the circles the entire national park in southern Chilean Patagonia. Unlike the famous W Trek, the O-Circuit includes the remote backside of the park where crowds disappear and the wilderness feels truly remote.
O-Circuit Quick Facts
Distance: 80 miles, 130 km
Difficulty: Moderate to challenging (I saw 70 year olds completing the loop)
Highlights: John Gardner Pass (best view of Grey Glacier)
The first half of the O-Circuit is quiet and remote, only about 30ish people did the circuit on the same day as me. The second half joins the famous W Trek resulting is crowded campgrounds and more people at the lookouts like Mirador Base Torres.

My 8-Day O-Circuit Itinerary
Here is the itinerary I followed while completing the loop.
Day 1: Base – Serón
I took the 7 am bus from Puerto Natales to Torres del Paine and arrived at 9am. At the entrance I went inside and booked my park entrance ticket which was $30 for the duration of the O-Circuit.. After booking my ticket I walked to the shuttles and had to pay $4,500 arg pesos for the 20 minute ride to the beginning of the trail. It is mandatory to take this shuttle as they do not allow people to walk to the start.
I started walking at 10am after shifting through the gift shop for a few minutes. The walk was 9.3 miles (15 km) and the map suggested it would take 5 hours to complete. I mopped around and stopped for a few snack/lunch spots and arrived after 3 1/2 hours. The walk on the way was beautiful but the trail was on an old road for the majority of the time making it feel like I was still somewhat connected to the world.
The check in for the campsite was not until 2:30 and I arrived to camp at 1:30 which is alright because they have a big kitchen area where everybody was hanging out out until check in. The campsite was huge, they had fancy tepee tents and also lots of space to setup tents which is what I did. There is even a small hill that you can use to protect your tent from the wind. I recommend getting to this campsite early if you are camping because the spots by the small hill are limited and will likely be gone by 3:30.
Day 2: Serón – Dickson
As I was packing up camp this morning and about to leave, I saw a puma about 75 yards in the distance on the trail I was about to walk across. This was a stark reminder that although I am following a trail and there are many people around, the wildlife is still something to be cautious of. The puma was massive and roamed around the campsite for the next half hour before wandering off into the distance.
The walk was 11.8 miles (19 km) and the park recommends 7:30 hours of walking until camp Dickson. I met a few people that skipped camp Seron and went from the entrance all the way to Dickson in one day which is a really long walk but doable if you don’t want to pay for an extra night of camping.
I left camp Seron at X in the morning and was one of the last people on trail for the day.
Day 3: Dickson – Los Perros
One of the quieter sections of the circuit leading toward glaciers and rugged terrain.
Day 4: Los Perros – Grey (John Gardner Pass)
This is the hardest day of the trek.
You climb to John Gardner Pass, where the trail suddenly opens to a jaw-dropping view of the massive Grey Glacierstretching across the horizon.
It was easily the most dramatic moment of the entire hike.
Day 5: Grey – Paine Grande
The trail follows the glacier and crosses long suspension bridges over deep valleys.
Day 6: Paine Grande – Frances
A spectacular side hike into the heart of the Paine Massif.
Day 7: Frances – Chileno
Rolling terrain with stunning lake views.
Day 8: Chileno – Base Torres – Exit
A sunrise hike to Mirador Base Torres, one of the most iconic views in Patagonia.

My Personal Experience Hiking the O-Circuit
The backside of the O-Circuit felt incredibly remote. Some days I would hike for hours and see only a few other people.
But the most memorable part wasn’t just the scenery—it was the people I met along the trail. Backpackers from all over the world sharing food, stories, and exhaustion after long days of hiking.
Crossing John Gardner Pass in the wind and suddenly seeing the enormous Grey Glacier below was one of those travel moments that stops you in your tracks.
For a few minutes nobody spoke. Everyone just stared.

Absolutely.
While the W Trek is famous, the O-Circuit offers something better: solitude.
The remote northern section feels wild and untouched, and completing the full loop gives you a much deeper experience of Patagonia.
For backpackers willing to carry their own gear and deal with unpredictable weather, the reward is one of the most unforgettable hikes on the planet.
Tips for Future Backpackers
- Book campsites months in advance
- Start John Gardner Pass early in the morning
- Bring strong rain gear

Final Thoughts
Hiking the O-Circuit in Torres del Paine National Park was easily one of the highlights of my travels through South America.
For eight days I walked through glaciers, mountains, forests, and valleys that felt almost unreal.
It’s challenging, sometimes uncomfortable, and occasionally exhausting—but it’s also one of the most rewarding adventures a backpacker can experience.
If you’re traveling Patagonia and wondering whether to attempt the O-Circuit, my advice is simple:
Do it.
It’s the kind of place that reminds you how small you are compared to the scale of nature.
