The entry point to the fabulous and magnificent Huesteca Potisina, in the Sierra Madre Oriental.
My suggestion:
If you don't have much time to spend in the region then choose Xilitla as your base. The village is worthy of the name Pueblo Magico!
My review
If you are going to Ciudad Valles, get ready for sweltering heat. But you will also be visiting one of the least well known and most spectacular areas of Mexico: Huasteca Potosina, the birthplace of adventure vacations in the country...
