Both companies have Facebook pages (, in Spanish), where they publish their bus timetables

If you miss your bus, to the national park and are short of time, you can hitchhike from Valdesina, which is a small settlement that is situated located on the road between Molina and Radal. You can take one of the minibuses or ("Aquelarremicros" minibuses ) to Valdesina, which leave RELATIVELY frequently from Curicó, and pass through Molina's bus terminal on the way. It's just a case of riding the minibus as far as it will take you, and then getting off before it turns around and goes back the other way. If you can't find a minibus with a "Valdesina" destination sign on its front, then just hop on one that has a "Tres Esquinas" sign on the windscreen. Provided you ride it all the way to the end, a Tres Esquinas minibus will take you almost as far up the Molina-Radal road as the Valdesina ones do.  Bear in mind that, if you are visiting the national park outside of the peak tourist season-- even in the BEST case scenario, you will at least have to hitchhike into it from Radal village because, as just mentioned previously, at the buses don't go beyond there outside of the busiest tourist periodsvery least.
