A wonderful drop! But in the same way, a tremendous climb to give you the desire, especially if you come from Cuernavaca. This is the road parallel to Huitzilac but longer and with less inclination, although it is not to be trusted since it has sections with "slopes" of almost 9% in its route full of vegetation that changes from humid heat to mountain cold, hopefully you will find mist on the way so be prepared for the experience; In cold weather you will feel moisture entering your body and in hot weather it will be a refreshing journey. There is no shoulder but enough space for the cars to reset the passage.
If you enjoy well-marked curves on a descent at a good speed, this section is great to enjoy, just be careful of the exit and entry of vehicles in some populated areas, although this federal highway is widely used, you can go without complications to your destination whether you continue to Morelos or beyond, the Zempoala Lagoons or connect with the Huitzilac climb to train tasty. By the way, also be careful at the Huitzilac-Cuernavaca junction since vehicles pass in all 3 directions. It is very well signposted. May you enjoy your way in each pedal stroke.
