The Torres del Paine W Trek is considered a difficult hike and is best suited for fit and experienced hikers. Intermediate hikes will see a little more change in elevation and hikes will start to increase in length. Advanced hikes are longer treks with steep descents and challenging switchbacks. Keep in mind, the weather in summer can change and you’ll also be packing a 35-50L backpack filled with water and other things you’ll need throughout the day.
