Best time for trekking

Patagonian summer from December to February is the warmest time with day temperatures between 12°C and 15°C when night temperature is between 9°C and 12°C. November – January and March get quite a lot of wind –  the biggest problem for hiking and camping in Patagonia. February is the least windy summer month. It’s the same with rain out of all summer months February gets the least rainfalls. Out of weather point of view February is definitely the best month for trekking in Torres del Paine. The main drawback of hiking in February is crowds, it’s the busiest month for the park with the most visitors coming here. It means you must book campsites long in advance to make sure you get a spot on planned dates. For more details read our post Torres del Paine complete guide

Guided or independent trek

Independent trek


  • It’s much cheaper.
  • It’s more adventurous.
  • The route is well-marked and easy to follow; distances, names, altitude profile etc. you don’t need a guide to show you the way. 
  • In season there are many hikers on the trail even if you walk alone you won’t be lonely.


  • You have to plan the hike, book campsites, buy food etc.
  • You’ll be carrying a heavy backpack for a week.
  • Setting a campsite by yourself; pitching tent, cooking, packing/unpacking after a long walking day. We love doing it but for some people it’s more pain than fun.

Guided tour


  • Easy – no arrangements, bookings, gear rental etc. your tour company will do everything for you.
  • Walking with a day-pack, your luggage will be transferred from campsite to campsite.
  • No cooking, pitching tent, packing etc.


  • Quite a bit more expensive.
  • Takes away the adventurous part of the hike.
