Go for a drive in to the Carretera Nacional towards Santiago. Recently assigned the title of "Pueblo Magico", this small town keeps a beautiful colonial architecture. The main square has a stunning church and a variety of restaurants for lunch or dinner. From traditional Mexican food to Italian this little square has for all tastes and budgets. The feel of the place is so peaceful that it makes it a great place to forget about the everyday stress and have a breath of fresh air.
There is a little market that is there every Sunday which sells crafts and also local cheese and honey. You can also take a 2 minute walk towards the church and you will find a set of stairs where you will get a stunning view of the mountains and the Boca Lake. The drive takes about 30 minutes from Monterrey off rush hour of course. If you want to go there on a Sunday try going around 11:00 am to avoid traffic, since this is a popular place for the locals.
On your way to Santiago you will also find "Los Cavazos" Local market on both sides of the motorway which sells a lot of crafts. Worth the visit if you have the time.
