Do I need a guide to hike in Torres del Paine?

You can hike the W Trek without a guide during the summer season, which typically lasts from October to April. This could vary depending on the weather. However, in order to hike the W Trek during the winter months, you must arrange for a certified guide.

Pay special attention to guide requirements if you have a reservation for September or April. You can usually find this information at https://www.pasesparques.cl/. The O Trek is closed for the winter and normally reopens around November. The hiking season for the O Trek runs until March, depending on the weather. As long as the O Trek is open, you do not have to hire a guide.
