We took a scheduled company bus to Petalan from Zihuatanejo for 19 peso pp. The casa nova left from the central bus station in Zihuatanejo and let us off at the Petatlan bus station, which was about 10 minutes walking from the church and gold market. When we returned we took a different bus for 12 peso pp. That bus picks up anyone on the road and drops you off in the center of Zihuatanejo. A lot of work is spent on some of these buses, decorating the inside, funky little buses!!
