We spent a day driving from Puerto Penasco to Golfo de Santa Clara (and back) - a very small fishing village on the coast of the Sea of Cortez. The town is much smaller than Puerto Penasco with a lot less American influence. We drove over on Highway 3 on a Monday and some of the vendors were still taking down their displays on the beach. Apparently, there is some sort of vendor mall on the weekends. Had we known this - we probably would have gone on a weekend, instead. We talked about going again another weekend, but it was about 130 km each way. We will go again another year.
