Our guide/driver spoke English. I can't overemphasize how important this is. He was also friendly, helpful, and extremely well-informed. The stop at the demonstration of native textile handcrafting was annoyingly long, but the rest of the trip was fine. On another trip, we will try to go with a larger group, and maybe also bring a folding stool for a place to sit and read while waiting for things to get interesting. If this seems harsh or unfair, it's probably because I'm not a natural tourist; I was dragged along by my wife, who says she had a great time.
