Taxi from Barro de Potosi to zihua

The taxi rate page says 380? meaning it is an educated guess. I would think a little higher ,but not a lot higher. You see taxis regularly going by. I've always left by about 4PM, so I don't know about nighttime availability. Many taxi drivers will come pick you up.

You can now take a bus also. Catch an aeropurto bus and get off just before entering the airport. Then go around the corner to the right and catch the Barre bus. Don't know the hours it runs,
