Let’s jump in.

Why the Rio Grande Valley Is One of the Best Wildlife Destinations in America

The Valley sits at a kind of magical crossroads — where the desert meets tropical forests, where Gulf Coast wetlands mix with grasslands, where migratory birds pass through by the tens of thousands, and where subtropical species from Mexico slip across the border.

This area doesn’t just “have” wildlife. It overflows with it.

You’ll find:

• Birds found nowhere else in the U.S.

• Butterflies by the hundreds

• Rare mammals

• Wild cats (yes, actual wild cats like ocelots)

• Reptiles, amphibians, and more

People travel from all over the world to see species that locals casually spot from their back porch.
