My previous attempt to see the Cajón del Maipo had been a bit half-arsed, relying on public transport and ending up in the nondescript hamlet of San Gabriel, instead of actually out in the mountains hiking.
So I tried again this weekend, with a couple of other ESO people. We hired a car, and left reasonably early. Having your own wheels definitely makes a big difference, and instead of spending hours on the bus chugging through all the distant Santiago suburbs, we were in the valley in less than an hour.
But we didn't get everything right. We stopped in Baños Morales for a lengthy and tasty lunch, planning to hike to a glacier afterwards. But by the time we rolled up to the national park entrance, sated and sleepy but none the less keen to hike, we were told the trail had closed 20 minutes earlier.
So we had to find something else to do. We randomly ended up spotting a large red rocky outcrop, high up in the hills above Lo Valdes, and decided to go there. It was a good hike, scrambling up some steep and precarious scree slopes. The skies threatened but only delivered a few spots of rain. We made it to the outcrop without getting wet, and from it we got awesome views over the valley.
After we headed back down, the heavens finally did open, but we were safe in our car by then, and we drove down the valley as the sun broke through the rain clouds again.
