Nuevo Leon

The Nuevo Leon area has some of the best canyons in Mexico, with Matacanes being one of the top canyons in the world.
How to get there
Fly into Monterrey airport (MTY) and rent a car. Or it is about an hour south of the border at Laredo, Texas. From SoCal it is often much cheaper to fly out of Tijuana Airport (TIJ), about 1/2 the price, and the new bridge "Cross Border Xpress" planned to open in 2015 will make this process a breeze.
Car Rental
Most car rentals in Mexico will offer much cheaper deals online, so better book in advance. However, most car rentals will often NOT include or even mention about the "mandatory insurance" that will then force you to accept once you are picking up the car. If the car rental if quoted for US $5 a day, the hidden "mandatrory insurance" will add US $30 to that rate. Hertz and Avis proudly advertise they do NOT charge such hidden fees to customers, and both offer discounted rates through Costco. When renting a car, better pay with American Express as it provides additional insurance to cover for loss of use, property damage and any other claims not covered by other insurances. VISA claims to offer the same level of insurance with some of their cards, but Amex offers a "no questions asked, customer is always right" procedure, while VISA does NOT.
Money Exchange
Bank of America offers customer the option to order Pesos online and receive them at their home withing 2 business days or even overnight for an extra fee. The exchange will be better than Travelex or any other "official exchange service" you can find. Another option is to get money from ATM in Mexico, and Bank of America customers will get great exchange rates and no ATM fees when using Santander ATMs.
