Zapo trekkin

I agree with seeing Monte Alban, bring a hat and water and good walking shoes. There is a lot of stair climbing, some steps being irregular but all worth it. I went this past January and took a combi that gathered people from hotels and dropped us off and returned later maybe in 3 hrs. Your hotel can set you up. There are guided trips as well or you can pick up a guide at the entrance. The site is pretty well signed in english and I did not feel a guide was necessary, though I did have to ask a few nationals questions where there was no signage in English. If you have a Inapam card the actual entrance fee is waived.

Eating lunch at the mercado where they serve foot long tortillas with lots of meat and spice is a treat. The vendors compete to get every customer they can snag.
