End: Day 8 at 9:30 in Puerto Natales Bus Station.
Day 1: Departure from Puerto Natales and Serón Trek (9 km, 5.6 miles, 4 hours).
The program starts in the Puerto Natales Bus Station to take the bus to the Portería Laguna Amarga, where you will enter the Torres del Paine National Park. After that, you will be able to take another ground transport to the Welcome Center, where you will have to register. After one of the best views of the Torres del Paine you can have from the starting point, if weather is good enough, you will enter the Patagonian landscape through a slope, the first test of the hike. You will have views of the surrounding valleys and the Cerro Paine, while you continue on the side of the Paine River until reaching Serón Campsite, where you will stay this first night.
Day 2: Dickson Trek (18.5 km, 11.5 miles, 6 hours).
After breakfast, you will take the route parallel to the Paine River, to get closer to the Cerro Paine side. You will go up by a steep track to the higher part that you will have to tour during the day, and in which you will have a privileged view of the surrounding mountains, besides the Paine Lake. Then, you will walk by the sides of the mount, parallel to the river. You will have time to stop in the Guardería Coirón for lunch and recover energy, before keep walking through the fields with views of granite walls. After that, you will see the Dickson Glacier in the distance, which means that that's the end of the hike for today. You will reach Dickson Campsite, near the lake with the same name and from the Paine River begins.
Day 3: Perros Trek (9 km, 5.6 miles, 4 to 5 hours).
You will start early to take the route marked by Los Perros River. You will go a couple of hours through a nothofagus forest to a small bridge to cross the river. There you will start going up the moraine until identifying the Los Perros Glacier, which is on the side of the lake with the same name. From that point, you will be a couple of minutes from the Perros Campsite, in which you will stay to face the challenge of the next day.
Day 4: Grey Glacier Lookout Point Trek (22 km, 13.7 miles, 10 to 12 hours).
The recommendation is getting up very early to begin the adventure. This morning will be necessary the use of a headlamp, because you will start walking before dawn. You will begin a demanding walk up in the middle of the woods and, while you go forward, you will be able to see the first lights of the sun over the park. You will continue the road to the John Garner Pass, the higher point of the trek at 1,200 meters (3,937 feet) of altitude that will test your strength and that, needless to say, you must do very carefully. Once in the pass, you will have the first view of the Grey Glacier and the beginning of the Southern Patagonian Ice Field, one of the characteristic images of the Torres del Paine National Park, which you will see for a while before descending through another forest. You will pass by the Guardería El Paso, where you can have lunch before keep walking to the suspension bridges, the road that borders the Grey Glacier. You will be able to take pictures and visiting some privileged points to admire the lake and the glacier, before reaching the Grey Campsite where, rightfully, you will get some rest.
*Depending on the weather conditions, the CONAF park ranger might forbid going up through the John Garner Pass and you would have to go back to Perros Campsite.
Day 5: Optional activity in the glacier and Paine Grande Trek (11 km, 6.8 miles, 4 to 5 hours).
You will start the trekking, walking that is much less demanding that the one the day before. You will border the Grey Lake, path in which you will have the last views of the glacier and the small icebergs, passing by the Los Patos Lagoon, before entering a small valley from where you can see the Pehoé Lake. You will get to the Paine Grande area, from where you will catamaran through the Pehoé Lake to Pudeto, where the bus will be waiting to take you back to Puerto Natales, where the activity ends.
