El Cajón del Maipo


A Brief History of El Cajón del Maipo

It's hard to imagine that millions of years ago the imposing mountains of Cajón del Maipo were submerged in the sea. They were a part of an old marine channel and today it is still possible to find traces of its aquatic past in the form of fossils that can be found high up in the mountains.

The first inhabitants of these highlands were the Chiquillanes Indians who lived around where San Gabriel is today.

Evidence of the Inca's presence can be found in this area too. A Mummy of an Incan boy of about eight years of age was found on Cerro El Plomo (Peak) in 1954. For nearly 500 years he had been there at about 20 meters below the summit (5424m). The mummy can currently be found on display at the National Museum of Natural History in very good condition. Notice how his hair is plaited in more than 200 braids.

In the beginning, San José de Maipo, arose out of the need of having a central establishment for the diverse mining communities that were settling down in the area. Most of them were working in one the first silver mines in Chile, "San Pedro de Nolasco", which earned a lot of money for the region at the time.

Around then, the Governor of the Kingdom of Chile, Mr. Ambrosio O'Higgins, aware of this need, established the Villa San José de Maipo on 16 of Julio 1792 by means of a royal decree of the King of Spain. Later the area was called Villa Alta, but nowadays it is known as San José de Maipo.

How to Get to the Cajón del Maipo

Travelling by car:

The main route to Cajón del Maipo from Santiago is by going along Avda. La Florida. This avenue intersects with another main avenue called Avda. Vespucio Sur (the intersection is known as the Rotunda (roundabout) Departamental). Avda. La Florida, which later changes its name to Avda. Camilo Henriquez, will take you directly to the Las Vizcachas area which is the beginning of the Cajón del Maipo.

Another way is by going along Avda. Vicuña Mackenna until you arrive to Puente Alto. From there you can take Eyzaguirre which will connect to the main route G-25 just before Las Vizcachas.

Another option from Puente Alto is to drive towards Pirque and then take route G-421. This road later connects to route G-25 at two different places; by crossing the bridge to Las Vertientes or continuing until it joins at the Puente El Toyo (Bridge).

If you plan to go deeper into the Cajón by car, San José de Maipo is the last place to fill up the petrol tank.

Route G-25 is paved up to San Gabriel but from there on up into mountains, the roads are made of gravel.

Travelling by bus:

Buses frequently leave from the terminal at Plaza Vespucio which is at the end of Metro line 5, the Bellavista de La Florida Station.

Buses usually go through Puente Alto before they head off into El Cajón del Maipo, so it can take a while before you see any decent scenery.


(while we cannot recommend Hitchhiking as a safe way to travel, we understand that many people do it anyway)

It's best to take a local bus up to Las Vizcachas and try your luck from there. It will be too difficult to get a ride from Av. La Florida. Remember that the further you go up into the mountains, the less traffic there is, especially during week days.

Some traffic that you may find in El Cajón del Maipo.

Some other routes that can take you deeper into the mountains are:

G-345 Cajón Río Colorado - Just after puente Colorado (Bridge)

G-355 Lagunillas - Just after San José de Maipo

G-455 Embalse El Yeso - At Romeral where the paved part of the route G-25 ends

Las Melosas - After Puente Negro which is after Romeral

G-421 El Toyo Pirque - The back road between Pirque and El Toyo


Don't go into the mountains alone and/or in bad weather. Remember that the weather can change dramatically and rapidly, especially in Autumn, Winter and Spring. Rain, fog or the feared "White Wind" (a strong storm of wind, ice and snow), can put your life in serious danger so check out the weather forecast for the time you intend to stay.

If you plan to go mountaineering or trekking deep into the mountains, you should let the local police officers (at San Gabriel) know what route you are planning to take and the day you expect to be back.

If you are fishing or hunting, you should respect the local regulations and permitted seasons.

Take care of the Natural Environment: don't throw away garbage, don't damage the flora and fauna. Take all the necessary precautions to avoid forest fires.
