Monarch butterfly tour

We did this trip with Carlos a few years ago and it was an incredible experience. http://www.zihuatanejo.net/tablero/index.php?id=112894

I, too, am a senior and was one at the time. I can't overstate how difficult the climb on foot would be. The ending elevation is about 10,000 ASL and the air is very thin. We took the horse up, thank God, and walked down and that was bad enough. My leg muscles were quivering by the time we got to the bottom.

The ride up was pretty smooth, actually.
