Sierra Gorda is a 95 square mile biosphere reserve spreading into four Mexican states. The terrain here is rugged. There are many waterfalls. And there are caves from which thousands of birds leave in the mornings, and return at night.
We planned to visit waterfalls and caves, but the weather turned gloomy. It’s no fun seeing waterfalls in the rain. And birds don’t leave the caves. But here are some pictures of what we did see.
