Self-Guided O Circuit: Torres del Paine Full Loop in 7 Days

Your self-guided O Circuit trek starts at the Puerto Natales bus terminal at 6:45 AM for the 7 AM public bus to Torres del Paine. The road crosses estancias and open Patagonian plains. Upon reaching Laguna Amarga (the park’s main entrance), present your park-entry QR pass before boarding a 20-minute shuttle ride bound for the Welcome Center.

From there you walk to Refugio Central, leave your bag, and set off up the Ascencio Valley. The trail climbs to the Windy Pass—an exposed section with strong gusts—then passes Refugio Chileno, the last stop with toilets, food for sale, and internet. Bring cash if you want to buy anything.

After a stretch of lenga forest and small streams, the last hour climbs a steep terminal moraine to the view of the Towers above their glacial lake. Come back down the same trail to sleep at Central.

Meals included: Box lunch / Dinner

Weather permitting, the day starts with dawn light on the Towers. Leave the busy side of the park behind and walk through an old beech forest, where you may hear woodpeckers or spot fresh puma tracks on the trail.

This is one of the easiest stages of the circuit: a well-marked path with a gentle incline and distant views of Cerro Paine Chico. Your pre-booked tent waits at Serón, in the north-eastern corner of the park.

Meals included: Breakfast / Box lunch / Dinner

The independent O Circuit follows the shore of Lake Paine, with Cerro Escudo, Cerro Cabeza del Indio (look for the face carved by nature in the rock), and the curved summit of Cerro Cubo around you. In spring and early summer, the slopes are full of wildflowers.

The stage ends at Lake Dickson, fed by Dickson Glacier on the border between Chile and Argentina. The campsite sits on the edge of the lake, with mountain views. The whole route is loaded in your offline navigation app.

Meals included: Breakfast / Box lunch / Dinner

Trek through ancient beech woodlands along the gentle course of the Los Perros River, surrounded by cascading waterfalls and towering peaks. A suspension bridge crosses the river to the foot of a terminal moraine that feeds a clear glacial lagoon.

A final 30 minutes brings you to Los Perros, the most rustic of the Torres del Paine campsites on this route, with only a cold-water shower and no flush toilets.

Meals included: Breakfast / Box lunch / Dinner

The hardest day of the O Circuit. Climb to John Gardner Pass at 1,200 m, where the Patagonian wind hits at full force. From the top, the view opens over Grey Glacier and the peaks of the Southern Patagonian Ice Field, a part of the park few visitors ever see.

The descent follows the edge of the glacier, up and down through a forest of fallen trees beneath the granite walls of the Olguín Range. Near Grey you may hear or see the ice calving into the lake.

Meals included: Breakfast / Box lunch / Dinner

The morning is yours at the foot of Grey Glacier. Walk to the glacier lookout, or, if you booked it in advance, join an ice hike with crampons or paddle a kayak among the icebergs on Lake Grey.

Later, the trail heads south through forest and over streams, with wide views of the Southern Patagonian Ice Field, and down past Laguna de los Patos, where you may see flightless steamer ducks. The campsite is Paine Grande, on the shore of Lake Pehoé.

Meals included: Breakfast / Box lunch / Dinner

The last day of your self-guided Torres del Paine trek goes into the heart of the Paine Massif. A winding trail leads to the French River—at the entrance of the French Valley, a gradual one-hour climb brings the first view of the hanging glacier at the top of the valley, then on to the French Valley viewpoint.

Return on the same trail to Paine Grande and board the catamaran across Lake Pehoé. On the other side, the pre-arranged transfer drives you back to Puerto Natales, where the trip ends.
