Reasons to hike the Full Circuit

Also known as the Full Circuit, the O Circuit runs right around the Paine range. Experienced hikers will enjoy the challenge of some of the tougher passes, and for beginners, this is definitely a hike to aspire to.

  • Complete a full circuit of the Paine range, visiting all the highlights as well as some hidden gems
  • Escape the crowds on the W Trek by continuing into the quieter northern areas of the park
  • Take on the challenging John Gardner pass to be rewarded by breathtaking views of the icecap stretching into the distance
  • Camp with a view at some of the national park's secluded campsites that hug the mountain range

O Circuit: the route

Starting at Refugio Torre or Paine Grande, you'll hike the full trek anticlockwise, visiting the three valleys of the W Trek as well as the quieter trails across the north. Stunning views and a sense of achievement await all who embark on this trail, and there is no shortage of highlights. The main areas to visit are:

  • Dickson Lake, a beautiful tranquil campsite with views of the Dickson Glacier
  • The hanging Perros Glacier which sits above the remote Perros campsite, one of your rest stops
  • The John Gardner Pass, during the most challenging day of hiking, where you will climb to 1200m for spectacular views of the icecap
  • Descend to Glacier Grey and follow the glacier as it meets Lake Grey
  • Hike through French Valley, with the vast hanging Glacier Frances dominates the landscape on your left as you climb
  • You will visit the magnificent mile-high granite towers that give Torres del Paine its name, either at the start or end of your trek. Climbing to this viewpoint is one of the more challenging days of the trek, with an 800m climb and 7-9 hours of hiking

O Circuit: FAQs

  • Do I have to camp?

    Yes, some nights of camping are needed as there are no 'refugios' at certain points along the route. Almost all the group trips have camping throughout, with an option to upgrade on certain nights.

    Remember that if you join a guided tour then you'll be very well looked after at each of the campsites; tents will be set up for you and good hearty meals prepared for you.

  • Will I have to carry all my kit?

    Generally speaking, the guide and their assistant will carry all the group equipment (tents, food, fuel, radio, first aid kit, safety equipment) and you will only be expected to carry your personal clothing, sleeping bag and sleeping mat. Sometimes people choose to hire a porter to help with this (often between two people), but in Chile this is expensive.

  • Do I need a guide?

    Many young Chileans hike this route independently, but it is very remote and not without its risks. The weather conditions change, and heavy snow is known to come down on the higher passes, so navigation can become very difficult; sadly this route claims one or two lives each year. With this in mind, we strongly advise joining a guided group, but for very experienced hikers we have occasionally arranged self-guided treks.

  • How wild and remote is the O Circuit?

    This route used to offer hikers a true sense of Patagonia at its most wild and remote, however it has become world famous and there are more and more people on the route. If you're looking to really get off-the-beaten-track, then let us know and we can advise on alternative routes within Torres del Paine and in other parts of Patagonia.
