Can I do the trek without reservations?

No. Park rangers check reservations at every campsite. You will be turned away if you do not have a confirmed booking for the specific night.

For the W or O circuits, you do not need a professional guide, as the trails are very well-marked and heavily trafficked during peak season.

Planning the Torres del Paine W or O Circuit

Planning a trek in Torres del Paine requires booking campsites or refugios 6–9 months in advance through two different private companies (Las Torres and Vertice). You must secure your permits before you even book your flights, as space is strictly limited and sells out instantly.

Choose your circuit. Select the W Trek (4-5 days, 80km) if you want the highlights, or the O Circuit (7-9 days, 130km) if you want the full loop including the challenging John Gardner Pass. The O Circuit requires a counter-clockwise direction.
Secure your accommodation. Check availability on the official websites of Las Torres and Vertice simultaneously. Build your itinerary based strictly on where you can confirm a bed or campsite for every single night of your trek.
Book your transport to the park. Fly into Puerto Natales (PNT) if possible; otherwise, fly to Punta Arenas and book the 3-hour bus to Puerto Natales. From there, take a morning bus (7:00 AM or 11:00 AM) to the Laguna Amarga park entrance.
Pay your park entrance fee. Purchase your CONAF park entrance ticket online through the official pasesparques.cl website before arrival. Print the PDF or save the QR code offline, as there is zero cell service in the park.
