Can you trek without a guide in Torres del Paine?

The W and the Circuit as well as the shorter walks in Torres del Paine National Park are well-known and well-used, the routes are well marked, and you’ll find plenty of other hikers on the trail – so yes, hiking independently is fine. I’ve hiked independently on the treks listed above. Whether you go solo or with one or more hikers is up to you and depends on your level of confidence – the northern part of the Circuit is quite remote, for example. If you’re camping, hiking with one or more other people allows you to share the weight of a tent, food and other camping equipment.
