Carry plenty of water on this section as water sources might dry out in early summer after all snow has molten.
Puente Alto is not particular safe area of Santiago, so residents recommend not walking very early in the morning or at night through this outskirt of Santiago.
Old entrance of regular route is closed by gate (S33° 37.320' W70° 32.182'). Better start from the public minor road and you won't have any problem (S33° 36.768' W70° 30.033'). The GPT Track File 2019 incorporates this change so follow the Regular Route if you use the current update.
Carry as much water as possible just before ascending to the pass (S33° 38.394' W70° 27.191'). There won't be water until 14 km further, and it's not of good quality (S33° 41.000' W70° 23.100').
Instead of deviating to El Melocotón, you can spend the night in Reserva Coyanco (camping, food, services), from where GPT02 starts. Just turn right at S33° 40.813' W70° 20.812'.

Regular route southbound. It took us 3 days as we started late in Santiago and arrived early in Melocoton. As it's still low season everything is shut down in Melocoton so we took the bus (which runs every 30 minutes) to San Alfonso, where we found nice cabañas and three small resupply tiendas.

The regular route and most options have been hiked and recorded by various hikers in recent years and feedbacks are incorporated in the track files. (2019)

Regular Route: The relative northern latitude and the maximum elevation of 2200 m should make remaining snow less of an issue in spring. Also no major river crossings are required on the regular route. Therefore this section should be traversable from early spring till late autumn. In spring parts of the route might be muddy due to snow melt. During winter heavy snow fall may occur in the elevated areas. (2019)

Option 1 Rio Clarillo: This option links GPT01 directly with GPT02 and is expected to open up later than the regular route due to its higher elevation. See the Recommended Travel Period of GPT02 for further information to this option. (2019)

This section does not incorporate any packrafting. This would make packrafting gear an annoying burden on the very steep ascents and descents of this section. (2019)

Regular Route: The regular route can be hiked in either direction. (2019)

Option 1 Río Clarillo: This options traverses the Reserva Nacional Rio Clarillo. When hiking southbound CONAF park rangers at the entrance near Pirque might not permit a traverse and insist that all hikers return on the same route. But when hiking northbound the Reserva Nacional Rio Clarillo is entered in a sector not monitored by CONAF. Leaving the Reserva Nacional at the entrance near Pirque will not be an issue therefore GPT01 Option 1 is currently recommended in northbound direction only. Combined with GPT02 this option is probably the more attractive finish for northbound hikers. (2019)

Hikers that took this option and have a good command of Spanish might talk to the CONAF park rangers and outline hike. This might facilitate acceptance by CONAF park rangers for southbound traverses of this attractive option. (2019)

Regular Route: The 40 km short regular route can be hiked in two demanding days or three more relaxed days. (2019)

Option 1 Rio Clarillo: This sections links directly with GPT02. See Section Length and Travel Duration of GPT02 for information to this subject. (2019)

Northbound hikers should avoid walking into Santiago in the late evening and either take a bus to the metro station Puente Alto or spend the last night in the mountains before walking into the populated areas of Santiago. (2019)

Regular Route: The regular route leads quickly out of the bustling capital Santiago and follows mostly a barely used minor road that was build for the construction and maintenance of an underground gas pipeline. This section is certainly not a highlight of the GPT but a worthwhile start. Especially hikers that advocate connecting footsteps will appreciate that you can walk in two or three hours straight from a busy subway station into the quite Precordillera. (2019)

Option 1 Rio Clarillo: For northbound hikers this option is probably the more attractive choice to finish their endeavour on the GPT. (2019)

Regular Route: The regular route requires a long, very steep ascent and descent that are physically demanding. But apart from this no mayor difficulties, technical challenges and dangers are known. (2019)

Option 1 Rio Clarillo: This sections links directly with GPT02. See Section Difficulty of GPT02 for information to this subject. (2019)

Resupply Town: Santiago

What you can't source in Santiago you probably don't get anywhere else in Chile. (2019)

Shopping: Food

If you want to prepare resupply packages with dehydrated food items you may find a reasonable good collection of imported products at the Jumbo Costanera Center that is conveniently located at the metro station Los Leones. But such resupply food packages are not really required as there are plenty of resupply towns along the GPT.

Shopping: Fuel

Gas canisters are widely available in large supermarkets, in "fereterias" and department stores.

Shopping: Equipment

See the Wikiexplora page Tiendas_de_equipo_outdoor_de_Chile.

Services: Restaurants

Services: Laundry

Services: ATM and Money Exchange

Accommodation: Hostals and Hotels

Accommodation: Apartments and Cabañas

Accommodation: Camping

Transport: Buses, Taxis and Fletes

Transport: Ferries

Not applicable.

Transport: Shipping Services

You find many offices of Starken and Chile Express all over Santiago.
