All year. Ideal at the end of May and beginning of June, when the oaks are bright red.
From Santiago, you must take the Pan-American highway (route 5) in the north direction. The detour to Rungue is at kilometer 54. You must take that exit and enter the town. Where the street ends, we must turn left and, a few meters further on, turn right (the street ends anyway) to cross an estuary. Immediately after crossing the estuary, you should turn left, and begin to skirt the estuary along a gravel road in good condition. The Rungue reservoir will then be bordered. After 3.9 kilometers from the Pan-American highway, there is a detour to the right ("A Caleu") which must be taken. This road, also gravel in good condition, goes through the valley and ascends progressively. Approximately on the 11th kilometer from the turnoff (14.9 from the Pan-American Highway) Caleu has been reached and a fork arises: you must take the left, which continues up the hill. 970 meters above, just before the passage to the valley of Olmué, the path to the oak tree appears on the right.
In public transport and hitchhiking
From the La Paz bus terminal, located on Avenida La Paz and Dávila Baeza street, daily buses depart for Til Til, from 6 AM and every 15 minutes. At 16.00, a bus leaves for Caleu. Passage value $ 1,600. It is quite a busy road, so the possibilities of hitchhiking are rather high.
Description of the route
The route starts at the access gate to El Roble, at 1242 masl (although it is possible to continue driving 4.1 kilometers more, up to 1680 masl). The route is very clear until the fork to Ocoa, because it is a vehicular road built for the construction and maintenance of the antennas of the summit. A normal weekend (especially after snowfall), there should be some cars on the road. It should start to walk towards the west. The road climbs without stopping until the fork. The first section is by the edge of this southern foothill of the hill. Then it reaches the edge that divides the valleys of Caleu and Olmué. To the west, there are beautiful views of the palmar of Ocoa and La Campana. Shortly after this first view of the Olmué valley, a pedestrian fork appears for the path that leads to Ocoa (1680 masl and highest point of the route). Turn left, heading west. For the summit of the Oak tree, you must continue along the main vehicular road, along the route described in Cerro el Roble (vehicular route). The route is wide and pleasant, in the shadow of the northernmost oaks of the Southern Hemisphere, and it enters with a gentle slope along the southern slope of the edge that separates the two valleys. After 2.3 kilometers, the footprint is passed to the northern slope of this edge, with more sun exposure, and the vegetation will flatten suddenly, disappearing oaks, but getting in return a beautiful view of the palmar of Ocoa at our feet. One more kilometer should be traveled along this wide route until it empties into an old quartz mine (on the southern slope).
At this point, a brief abrupt stretch begins for the cyclists (no problem for the walkers) marked as "Steep section" on the map (if you continue advancing on the edge, you will cross the route Caleu - Olmué) . You must go down a few meters to the step that separates the two valleys, where there are records of camps. On the left you can see a path that leads to the valley of Olmué, but you must take the little marked path on the right. This zigzags down the slope, between the bushes and thorns, descending sharply from 1404 to 1135, point where it joins the path "La Mina" of the Palmas de Ocoa National Park and where the route becomes "civilized" for cyclists. A few meters further on, you must cross a wooden bridge in very bad condition, and then continue a nice descent. A little later, the first palms appear. After a long stretch along the same slope, you will reach a sign that says "Waterfall: 0.5 km" on the right, marked as "cascade bifurcation 2" because this path is more common to travel in the opposite direction. It is possible to visit the waterfall and return (it's worth it). Then the trail crosses a stream with water all year and continues down to another fork to the same waterfall, marked as "cascade bifurcation 1". Then you come to the Casino sector, with many palms, and then to the upper parking lot ("El Peral") to finally reach the entrance to the National Park, where there are park rangers.
- If the route is made in the direction described (Caleu - Ocoa) it is perfectly possible (especially on a bicycle but also on foot) to climb to the summit of El Roble (see Cerro el Roble (vehicular route), then go down and take the fork to Olmué.
- When the steep section ends and the "La Mina" trail is reached, you can turn right and, only 200 meters further on, you reach the quartz mine and a mysterious bus abandoned in the middle of the ravine (? ).
- From "cascade bifurcation 2", you can take the detour to the waterfall and then, instead of going back to the route you came from, continue on that path until you join at "bifurcation waterfall 1".
- Trekking: At a normal pace, this trekking should take about 4 to 5 hours between the access gate to Oak and CONAF de Ocoa.
- Mountain Bike: About two and a half hours to three hours.
It is possible to shorten both times in about 40 minutes if you drive up to the fork to Ocoa.
- Checklist: Aunque sepas perfectamente lo que debes llevar, es preferible chequearlo al empacar. Esta ruta ha sido clasificada como Type 1 equipment checklist: low altitude route, without camping, snow or cold.
- It is recommended to bring a headlight to go through the first meters of the quartz mine that gives its name to the "La Mina" trail (the one in the Ocoa valley, not the one on the edge)
- The section from the "waterfall bifurcation 2" is described in more detail in P.N. La Campana, Ocoa
- It is not recommended to make a round trip by bicycle: there is a quite heavy section of 200m of unevenness where you have to carry the bike on your shoulder.
